Many times in life, One-size-fits-all can be really great! It takes the stress out of finding the right fit and is often quick, easy and convenient. But when it comes to contact lenses, one-size-fits-all is not only an uncomfortable, but also a potentially damaging, concept that can result in serious vision and eye issues. Contact lenses generally sit directly on the cornea, making it very important that the measurements of your contact lenses are 100% accurate to ensure a comfortable, healthy fit. This will prevent eye infections and other eye conditions such as corneal abrasion, a painful scratch on the surface of the eye that can make even blinking uncomfortable!

Switching from glasses to contacts or changing your contact lens prescription are processes best overseen by an eye care professional that will measure your eyes properly and find the best fit for you. Below, Dr. Charlie Alfano of Freelton Eye Care in Freelton, On walks us through some of the most important parts and points of proper contact lens measurements and fitting.

Taking Measurements

Each person’s eyes are just a little bit different. Some corneas are steep, while others are shallow. Some people have mild astigmatism, while others’ astigmatism is more severe, and yet others don’t have at all. All these considerations and more make proper corneal measurements a very important starting point. Your eye’s curvature will first be measured using a measuring device known as a keratometer. This is a very simple procedure, in which you simply rest your chin on a support while the instrument takes photographs of your eye. These photographs are used to analyze reflections of light from your cornea to help the doctor determine the exact curvature of your eye and the size of contact lens that you will need.

In a case in which a patient has a hard-to-fit cornea, based on an unusual curvature of the eye, further computerized measurements are often taken using corneal topography, allowing a more precise picture of the shape of the corneal surface.

With astigmatism the surface of the eye is irregular and causes poor focusing. In this case toric contact lenses, which are made specifically to correct the distortions of the eye caused by astigmatism and requires more detailed measurements than a standard lens.

It is also important to get an accurate measurement of the pupil, the opening at the front of the eye where light enters, as well as the colored part of the eye, the iris. This is measured either with a ruler or with an automated device.

Your eye doctor may also perform a tear film evaluation in order to assess if you are prone to dry eyes. If you are, your eye doctor may be able to prescribe you specialty lenses that help keep the eye properly hydrated and prevent dry eye symptoms such as red, itchy, uncomfortable eyes.

The Fitting

After completion of all the required measurements, your eye doctor will know what type and shape of contact lens you require. Many doctors give their patients a trial pair of lenses to try on at this point. An instrument called a biomicroscope may be used for a magnified view of the cornea with the contacts in, to assess the fit. This same instrument can also be used to detect and assess any change in the health of your eyes after beginning contact lens wear. You are likely to also have a number of follow-up visits after the initial fitting. These visits are meant to ensure that your eyes are remaining healthy with contact lens use. Your doctor should be able to order your permanent prescription after the second or third visit, assuming that he or she has not seen any damage to your eyes from the trial pair and has confirmed that the fit is proper.

It is important that your lenses be properly fitted to your eyes for maximum comfort and health at all times. For more information, contact your eye doctor today.

Contact lens overuse is an increasingly common eye condition that has significant potential to do serious damage to your eyes, and lead to major eye and vision issues in the future. Dr. Charlie Alfano of Freelton Eye Care in Freelton, Onatrio comments “Contact lenses represent a great way to enhance how you look and feel while allowing you to maintain your best vision. But, they pose a very real risk of damaging your vision if you don’t know how to care for and use them properly. It is important to know what to do to allow safe wear of your contacts and avoid this increasingly prevalent and dangerous eye condition.”

The 18 Hour/Week Rule

Your eyes require oxygen just like a person, and denying them the opportunity to breathe properly by overwearing your contact lenses can cause severe damage to your eyes. But, how much is too much when it comes to contact lens wear? To answer this question, eye care professionals have come up with a standard benchmark: If you come in anywhere less than 18 hours a week with your contact lenses out, you are overwearing your contact lenses. When denied oxygen in this way, the eye may attempt to supply oxygen through neovascularization. This process involves the growth of new blood vessels into parts of the eye that should remain clear and unblocked for your best vision. This can seriously hinder your ability to see, and do serious long-term damage as well.

Spare Glasses: Your First, Best Tool To Protect Your Vision

In working on reducing your contact lens wear, a spare pair of glasses can be your best friend. Studies have shown that wearing your glasses instead of your contacts as little as once or twice every week can significantly reduce your chances of developing symptoms of contact lens overuse by allowing your eyes to rest from the strain put on them by consistent contact lens wear.

Even on days when you choose to wear your contacts, it is possible to take steps to reduce your chances of over wearing your contacts. One easy way to do this is to wait to put your contacts in when you wake up in the morning. Wear your glasses during your morning prep, and put your contacts in as the very last step before leaving for the day. Taking your contacts out as the pirst part of your bedtime prep is another great way to help yourself. These two methods combined can significantly reduce your chances of contact lens overuse without having to make much conscious effort to do so.

Never Sleep With Your Contacts In

Sleeping with your contact lenses in is among the leading causes of contact lens overuse. This practice is among the most dangerous and damaging of the many poor lens wearing choices a person can make. Overnight contact lens wear, or even wearing them for a short nap during the day, may deny the eyes essential oxygen and hydration, possibly leading to vision threatening infections and a painful scratch on the surface of the eye called a corneal abrasion, which can cause eye pain, light sensitivity and excessive tearing. Removing your contact lenses, even for a short nap, is an essential step toward guarding your long term eye health.

Follow Instructions, Save Your Eyes

Possibly the most important part of preventing contact lens overuse is paying close attention to the replacement schedule prescribed by your doctor. Time lines for contact lens replacement are established to protect your eyes from the potentially harmful consequences of contact lens deterioration and calcium deposits that build up on your contact lenses over time. Many people believe that as long as their contacts are comfortable to wear, there is nothing wrong and no need to replace them. Optometrists have fought against this harmful myth for years. By the time contact lenses are uncomfortable, they may have already begun to damage your eyes in ways that may affect your sight long term. Whether in an attempt to save money or through simple inattentiveness, wearing your contact lenses beyond their prescribed replacement date is an incredibly harmful practice that could have serious long term consequences.

Eye Doctors Weigh In: How Smoking Can Harm Your Vision & Eye Health

We all know that smoking is bad for you, especially the risks that it poses to your heart and lungs. What many people do not know is that cigarette smoke negatively affects your eyes and vision too. As our eye doctor can explain during your next eye exam, smoking has been directly linked to an increase in the risks of both cataracts and macular degeneration, two leading causes of vision loss, and it is believed to be a factor in a number of other eye and vision issues.

Smoking and Cataracts

Studies show that smoking doubles the risk of cataracts and with heavy smoking, the risk triples. In fact, there seems to be a direct correlation between the amount of smoking and the likelihood of cataracts. Cataracts are characterised by the clouding of the lens of the eye and it is believed that smoking affects the cells of the lens, accelerating this process.

Cataracts are a leading cause of vision loss worldwide, however they can be treated surgically by removing the clouded lens and replacing it with an artificial one. Symptoms include:

• • Blurred, cloudy or dim vision
  • Sensitivity to light and glare
  • Presence of halos around lights
  • Increasingly poor night vision
  • Fading color vision
  • Double vision
  • and frequent prescription changes with minimal improvement in vision

Smoking and Age-Related Macular Degeneration

According to medical research, smoking increases the likelihood of developing age-related macular degeneration between two and four times the normal risk – the more you smoke, the greater the risk. Unfortunately, there is also an increased risk for those exposed to cigarette smoke for extended periods of time.

Age-related macular degeneration or AMD is a condition in which the macula, which is the center of the retina, begins to to deteriorate, reducing central vision and the eye’s ability to see fine details. The disease is characterized by blurred and distorted eyesight and blind spots in the central vision. With time, the disease can progress to leave the person with low vision, which is significant vision loss that cannot be corrected by eyeglasses, contact lenses or refractive surgery.

Other Eye and Vision Risks of Smoking

Smoking has also been linked to dry eyes, optic nerve damage and diabetic retinopathy (for those with diabetes).

“Eye Vitamins” are often used without doctor’s recommendations. Smokers are cautioned not to take beta-carotene supplements, specifically, (or multi-vitamins containing this ingredient) as studies indicate there is increased risk of cancer even in people who quit smoking.

What to Do?

Even if you have been smoking for years, quitting will reduce the risks of developing these conditions, for yourself and those around you. If you do smoke, make sure to schedule a comprehensive eye exam every year to catch any developing disease early. Early diagnosis and treatment can be the key to saving your vision and preventing permanent vision loss.

In an effort to spread the word to increase awareness about Sjogren’s Disease, eye care providers are speaking out about this hard-to-diagnose condition.

As our eye doctor can explain during your next eye exam, Sjogren’s is a systemic autoimmune disorder that can affect the whole body. One of the primary symptoms is excessive dryness particularly in the eyes and mouth. Other serious symptoms include chronic fatigue and pain, specifically in the joints, as well as major organ dysfunction. The syndrome also increases chances of neuropathies and lymphomas.

The severity of the disease varies greatly, ranging from mild discomfort to debilitating symptoms that can seriously impair normal functioning in everyday life. Early diagnosis and treatment can prevent serious complications and improve quality of life. There is currently no cure for Sjogren’s, yet there are treatments for many of the individual symptoms. On average patients are prescribed upwards of 8 medications to treat the wide range of symptoms.

Women are nine times more likely to develop Sjogren’s than men and diagnosis usually occurs around the age of 40. Unfortunately, because the symptoms vary from person to person, and the disease often occurs in the presence of or mimics other diseases (such as lupus, rheumatoid arthritis, menopause, allergies or multiple sclerosis) the disease is often misdiagnosed or overlooked. Further, because the symptoms can affect different parts of the body system such as the teeth, eyes or musculoskeletal system, various health professionals are sought to diagnose or treat specific symptoms (such as rheumatologists, dentists or eye doctors) while the big picture is often missed. On average it takes almost three years to obtain a Sjogren’s diagnosis once symptoms are noticed.

Since dry eye is one of the most common early symptoms of the disease, there has been an effort to educate eye care providers to recognize and to be aware to look for symptoms of the disease. Patients also need to be aware and proactive about speaking to their health care providers about potential diagnosis and treatment. Knowing the risk factors and symptoms can be imperative to a faster diagnosis.

Your eye doctor may be able to detect and diagnose Sjogren’s syndrome from dry eye symptoms as well as other diagnostic tests and review of symptoms. With this diagnosis the treatment will be different from typical dry eye disease. Since it is an autoimmune disease, lubricating eye drops may provide temporary relief but will not address the source of the problem. Your doctor may prescribe newer cyclosporine drops as well to treat the inflammatory response. If you have dry eyes and typical treatments aren’t working, it may be worthwhile to ask about Sjogren’s.

Sjogren’s patients often feel misunderstood because most of the debilitating symptoms are not visible to others and the disease is often not recognized largely due to a lack of awareness. By increasing both public and professional awareness, the goal is to reduce diagnosis time and to advance research on the cure for this disorder.

Hey women! Did you know that women are more likely to suffer from vision problems and are at higher risk of permanent vision loss than men? Well 91% of the women surveyed recently didn’t know that, which means that many of them aren’t taking the necessary precautions to prevent eye damage and vision loss.

According to a recent study, the statistics for many of the major vision problems show that women have a higher percentage of incidence than men. These include:

• Age-related Macular Degeneration 65%
• Cataracts 61%
• Glaucoma 61%
• Refractive Error 56%
• Vision Impairment 63%

As our eye doctor can explain during your next eye exam, women are also more susceptible to develop chronic dry eye, partially because it is often associated with other health issues that are more common in women such as ocular rosacea which is three times more prevalent in women. Hormonal changes during pregnancy and menopause can also contribute to dry eye.

It’s important for women to know the risks for eye-related diseases and vision impairment and the steps they can take to prevent eventual vision loss. Here are some ways that you can help to protect your eyes and save your eyesight:

• Find out about family history of eye diseases and conditions.
• Protect your eyes from the sun by wearing 100% UV blocking sunglasses when outdoors.
• Don’t smoke.
• Consume a healthy diet with proper nutrition and special eye health supplements as prescribed by an eye doctor.
• Adhere to contact lens hygiene and safety.
• Adhere to cosmetic hygiene and safety precautions.
• Protect your eyes against extended exposure to blue light from computers, smartphones and LED lamps.
• If you are pregnant or planning to become pregnant and have diabetes, see an eye doctor for a comprehensive eye exam. In women who have diabetes, diabetic retinopathy can accelerate quickly during pregnancy and can present a risk for the baby as well.

Mothers are often charged with caring for the eye health of the entire family, but too often their own eye health needs fall to the wayside. It is critical that mothers take care of their eyes and overall health so that they can be in the best condition to care for their families.

Speak to your eye care professional about your personal eye health and vision risks and the precautions and measures you should take to protect your eyes. Encourage the other women in your life to do so as well. Once vision is lost, it often can’t be regained and there are many steps you can take to prevent it with proper knowledge and awareness.

The most important way to prevent vision loss is to ensure you schedule regular eye exams. Don’t wait for symptoms to appear as many eye issues are painless and symptomless, and sometimes by the time you notice symptoms, vision loss is untreatable.

There is nothing worse than a dirty spot on your glasses – well except perhaps many dirty spots or smudges. When that happens, most of us are tempted to grab the corner of our shirt and wipe it off, but resist the temptation – this is actually not a good idea.

As our eye doctor can explain during your next eye exam, there is a right way and a wrong way to clean your glasses. Cleaning your glasses properly will not only remove irritating dirt and smudges, but will also prevent your lenses from getting scratched allowing you to see your best.

You want to make sure that the materials you use to clean your lenses are clean and soft. The reason your shirt corner is not the best option is because it likely contains dust or particles that can scratch your lens. However, you don’t need fancy, lens cleaners either. In truth the best cleaner for your glasses may be more simple than you expect –

Gentle Dish Soap

That’s right, a gentle dish soap, warm water and a clean, dry soft cotton towel are the best tools you can have for cleaning your lenses.

Simply rinse your glasses in warm water and apply a small drop of soap (make sure to use a brand of soap that is lotion and moisturizer free). Rub the soap into the lens with your fingers and rinse thoroughly until all of the soap has been removed. Gently shake the glasses to remove excess water and then dry with a clean, dry, lint-free towel.

You may be wondering about the microfiber lens cloths and spray cleaner you get from your optician. These lens cleaning packs are great for when you are on the go and don’t have access to a sink and dish soap. The microfiber cloths are also great for polishing dry lenses after any dust or particles are blown away- just make sure they are cleaned regularly. For a real, thorough clean however, we advise that you use the technique above.

Cleaning Don’ts

Don’t use vinegar, glass or window cleaner, bleach, ammonia or spit/saliva for cleaning your lenses. The chemicals could strip off the coatings on your lenses, and saliva – well, it just doesn’t work. In particular, many lenses these days have anti-glare treatments that are especially prone to damage if not cleaned properly and are particularly vulnerable to window cleaners and alcohol.

Remember once your glasses are scratched, there is little to do to repair them. If you see something on your lens try to blow or brush it away carefully before you use a cloth to clean your lenses.

Keeping Your Lenses Clean

To avoid dirt and smudges, always take your glasses off with two hands using the arms of the frame and avoid touching the lenses. Further, the best way to preserve your glasses and keep them clean is to keep them in a case when they are not in use. It’s worthwhile to get an extra case or two to have on hand in the car or in your purse for times that you need to take your glasses off. If you notice swirled or circular scratches on your lenses, those are almost always from improper cleaning so make sure to take the time to clean them properly the next time.

Blue light. Do you know what it is? Do you know where it comes from, or how it can be harmful to your eyes? If you don’t know the answers to these questions, you are not alone, yet it is important that you become aware to protect your eyes for now and the years to come.

As our eye doctor can explain during your next eye exam, the reason blue light is suddenly becoming a big issue is because other than the sun, which is the biggest source of blue light, a significant source of blue light emission comes from digital devices and artificial lighting. As our world becomes increasingly digital – think: HD televisions, LED lights, computers, smartphones, tablets – we are all exposing our eyes to more and more amounts of blue light than ever before. And we are only beginning to understand the long term effects this has on our bodies and our eyes.

One of the biggest issues with blue light is that whether it is through work or leisure, people are exposed to screens at a close range for a large portion of the day. A survey from the Vision Council entitled, “Blue Light Exposure and Digital Eye Strain” recently showed that 87% of respondents used digital devices for more than two hours a day and over 52% regularly used two digital devices as the same time. This shift has drastically increased exposure and the number of symptoms that are reported. To date, research has shown that there are a number of ways blue light can impact your eyes including digital eye strain, sleep disturbances and retina damage that can lead to long term problems including serious eye diseases.

Digital eye strain is a condition that is characterized by dry, sore, tired or burning eyes, eye fatigue and sensitivity to light. It can also cause blurred or double vision, headaches, back, neck and shoulder aches and difficulty focusing or concentrating. These symptoms are most common in individuals that sit in front of the computer for two or more hours a day.

Studies show that exposure to blue light right before bedtime can cause disruptions in sleep and wakefulness because it causes a shift in the levels of melatonin, a hormone which affects your circadian rhythm and therefore your sleep patterns. So if you are using your smartphone to wind down in bed, put it down and dust off an old hardcover book!

Retina damage has been found to be a possible result of long term blue light exposure causing damage to the retinal cells in the eye which are responsible for clear vision. There has been evidence that this type of damage can lead to age-related macular degeneration (AMD) and cataracts later in life. In certain cases, your doctor might recommend Lutein and Zeaxanthin nutritional supplements to protect the macula from blue light damage.

Despite these risks, few people are taking action to protect their eyes from blue light. A recent study from Transitions Optical, The 2017 Employee Perceptions of Vision Benefits Survey, showed that there is also a significant generational difference in knowledge, habits, and attitude regarding blue light with millennials being more aware and concerned about the health effects it has on their eyes. Millennials are more likely to request prescription eyewear that has blue light protection and to know whether their current pair has that extra coverage. However, even the millennial generation is significantly lacking in awareness and prevention.

The best way to gain awareness of and protection against blue light is to speak to your eye doctor. There are a number of ways you can protect your eyes which include computer glasses, blue light lens filters, or even blue light filter screen protectors or apps that reverse screen colours for those that don’t use prescription eyewear. Each individual can find the best solution based on lifestyle, work environment and personal comfort. The most important takeaway is that you understand that blue light is an issue, take responsibility for your eye health and speak to your eye doctor about the best blue light solutions for you and your family.
