Why You Regularly Need to Replace Your Sunglasses

Did you know that sunglasses, or at least sunglass lenses, regularly need to be replaced? 

According to a study conducted at the University of São Paulo, the UV protection that sunglasses provide deteriorates over time. You may adore your current ones, but if you’ve been rocking those shades for two or more years, it might be time to get a new pair. 

In addition to the UV-blocking properties, anti-reflective and anti-scratch coatings wear down, and the frame material may become brittle over the years, too. Even if you have the most durable sunglasses available, regular lens-replacement is the best way to ensure that your vision is maximally protected from the harmful effects of ultraviolet light. 

UV Light and Sunglasses

The protective efficacy of your sunglasses comes in large part from the lens coating of dyes and pigments that reflect and absorb ultraviolet radiation. They create a barrier that prevents UV radiation from penetrating your eyes.

However, this protective coating can, and often does, break down over time. Wear and tear can cause an invisible web of tiny abrasions, compromising its UV-blocking power. Furthermore, the protective dyes and pigments aren’t able to absorb UV rays indefinitely; the more sunlight they’re exposed to, the more rapidly they’ll become ineffective. 

A pair of shades worn on occasion and in mild conditions is likely to remain effective longer than a pair that is heavily used in a more intensely sunny environment. For example, if you spend long days on the water paddling, kayaking, or canoeing, the protective coating on your lenses will deteriorate more quickly than it would if you only wear your shades to go grocery shopping or sit in a cafe. 

Why It’s Important to Protect Your Eyes From UV

Protecting your eyes from the sun is critical no matter where in the world you are, as UV exposure places you at risk for developing eye diseases like eye cancer, pterygium, and pinguecula — which can result in disfigurement and discomfort — as well as cataracts and macular degeneration — which cause vision loss and, in severe cases, blindness.

Even short-term overexposure can result in photokeratitis, a corneal sunburn. Symptoms include eye pain, swelling, light sensitivity, and temporary vision loss. Some people experience it when spending too much time boating or skiing without wearing eye protection. Snow and water can increase solar exposure because they reflect sunlight toward your face.  

What to Look for When Getting New Sunglasses

When choosing new sunglasses, make sure they’re labeled 100% UV protection or UV400. Although most pairs sold in the United States and Canada offer this degree of protection, it’s still worth confirming before making the purchase. Keep in mind that factors like cost, polarization, lens color, or darkness don’t have much to do with the level of UV protection. Even clear prescription lenses can be UV protective. 

It’s important to note that there is a lot of counterfeit sunwear in the marketplace. This is dangerous since counterfeit eyewear may not provide much-needed ultraviolet protection. So if the price of a renowned brand is too good to be true, it’s probably a fake. 

The size and fit of the sunglasses is important. Bigger is definitely better if you spend a lot of time outdoors. Larger wrap-around eyewear is best if you regularly ski or spend many hours in the water, as this style blocks light from all directions. 

To find out whether it’s still safe to wear your favorite shades, visit a Providence eye doctor to determine whether your lenses still offer the right level of UV protection. It’s also a good opportunity to discuss prescription sunwear.

Does Obesity Impact Eye Health?

Nation-wide awareness about the vast dangers of obesity is at an all-time high, with TV shows like “The Biggest Loser” and health initiatives such as Michelle Obama’s “Let’s Move!” campaign shining a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.

Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer — but researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Professor Michael Belkin and Dr. Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Center, found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness: 

  • Age-related macular degeneration (AMD)
  • Cataracts
  • Glaucoma
  • Diabetic retinopathy

The researchers said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the optometric risks of obesity which can help motivate people to shed those extra pounds.

How Obesity Contributes to Eye Disease

A Body Mass Index (BMI) of 25 is considered overweight and above 30 is regarded as obese. A high BMI is tied to several chronic systemic health conditions such as diabetes, cardiovascular disease, and stroke, among others. Recent research indicates that a handful of ocular diseases can now be added to that list. 

Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss. 

The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.

Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair! 

Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.

A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease

Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.

An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases. 

We Can Help Keep Your Eyes Healthy in Providence

While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams with Dr. John E. Ormando can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.

If you have any questions or concerns regarding your vision or eye health, don’t hesitate to call Westminster Eyecare Associates — we’re here for you. 

How Smoking Impacts Vision

Smoking harms nearly every system in your body — including your eyes. 

Though we are all aware of the health effects associated with smoking, such as lung cancer, heart disease, and bad teeth, few know about the negative impact it can have on our vision. 

Smoking and Eye Disease 

Smoking, especially 20 cigarettes or more daily over a long period of time, can adversely impact your vision. Cigarette smoke is made up of compounds that can damage health and have been shown to cause cerebral lesions which affect the area of the brain that processes vision.

More specifically, tobacco addiction increases the risk of developing vision-robbing diseases such as macular degeneration (AMD), cataracts, glaucoma, diabetic retinopathy. Moreover, smoke is an irritant that can cause or exacerbate dry eye syndrome. Below we’ll delve a little further into each of these conditions. 

Age-Related Macular Degeneration 

Smokers run a high risk of developing AMD, a condition that severely impairs central vision, making it difficult or impossible to read, drive, recognize faces and colors, and leads to permanent vision loss in those aged 65 or older. Fortunately, the risk can be dramatically diminished by putting an end to tobacco smoking — even if later in life. 

Cataracts

Heavy smokers double their risk of developing cataracts, the leading cause of blindness. Cataracts are characterized by clouded, blurred or double vision, photophobia, and reduced night vision. However, cataract surgery is common and replaces the clouded lens with an artificial intraocular lens. 

Uveitis

Uveitis, the inflammation of the eye’s central layer, is an ocular disease that can lead to blindness. This condition damages important structures of the eye, notably the iris and retina, and can lead to cataracts, glaucoma and retinal detachment. Smokers have a 2.2 times higher risk of developing uveitis than non-smokers. 

Diabetic Retinopathy

Smoking raises one’s risk of developing diabetes by up to 40 percent thereby increasing the risk of retinopathy as well. Diabetes damages the blood vessels in the retina, causing them to leak blood into the eye, which — in severe cases — can deprive the retina of oxygen and result in blindness.

Dry Eyes

Dry eye syndrome is a common eye condition characterized by insufficient tears to keep your eye lubricated, or the tears are not composed of the correct balance of water, lipids, and mucous to maintain proper lubrication. Common symptoms include red, itchy, and gritty eyes.

Heavy smokers, and those exposed to secondhand smoke, not only double their risk of developing dry eye but also exacerbate an existing condition, especially among the contact lens wearers.

Secondhand Smoke and Eye Disease 

Secondhand smoke— which includes the smoke that emanates from the end of a cigarette as well as the smoke exhaled— is nearly as harmful to health and vision. Second-hand smoke places others’ eyesight in danger, particularly in young children and infants. Furthermore, studies indicate that women who smoke during pregnancy put the newborn baby at risk of being born with eye disease or visual impairment that could affect his or her ability to learn.

Stop Smoking to Save Your Vision

The good news is that giving up smoking can have an immediate effect on your health — and it’s never too late to quit! Once the habit is broken, your body will begin to repair itself to prevent vision loss. It can be challenging to quit, as it requires dedication, support, and advanced planning. Dr. John E. Ormando and the rest of the staff at Westminster Eyecare Associates in Providence care about your health and will be happy to provide any assistance or resources to help you quit smoking and improve your eye health. Keep in mind that if you smoke, quitting smoking is the most important step you can take to protect your health and vision.
