Many people are cheered by a bright, sunny day, but the effect of all that sunlight on the eyes is a less sunny proposition. UV and glare can create a variety of issues, from dangerous “snowblindness” to irreversible disorders that threaten your eyesight. Here are some frequently asked questions about the role of sunglasses in protecting the eyes from harm. If you want to know more about choosing the right sunglasses, call Dr. Ostrom at (860) 669-2020 today.

What are UV rays? UV stands for ultraviolet, a band of spectrum invisible to the eye. Ultraviolet light consists of UVA, UVB, and UVC rays. UVC rays are stopped in Earth’s atmosphere before they reach the eye, but UVA and UVB can both reach the eye and potentially damage it.

How does UV affect unprotected eyes? UV rays can cause proteins inside the lens to become opaque or cloudy, a condition known as cataracts. Cataracts can make interfere with night vision, reduce your ability to see colors, and make reading difficult; they cannot be reversed, only removed. UV exposure can also cause retinal damage, changes in the eye tissues, and a temporary but irritating “sunburn” of the cornea called photokeratitis.

How do I know my glasses will protect my eyes? Choose glasses that claim to block at least 99 percent of UV rays — UVA as well as UVB. Look for label reading “UV 400,” since this designation means that the glasses block UV rays as small as 400 nanometers, providing 100 percent eye protection. Of course you need to protect your eyes from the glare caused by the visible spectrum as well. To accomplish this, select products that block 75 to 90 percent of visible light.

What are polarized lenses? Polarized lenses are specially designed to filter out certain types of glare that tend to radiate upward from horizontal surfaces when sunlight bounces off of these surfaces. They are recommended for tasks such as boating, fishing, skiing, golfing, jogging, and driving. Most polarized lenses will bear a label identifying them as such.

What types of glasses can I choose from? We are able to provide you with a wide range of sunglass options. If you normally wear glasses to correct your eyesight, you may be happy with a non-prescription pair of clip-ons or wraparound glasses that simply fit over your lenses. If you’d rather not wear that much equipment on your head all at once, you can order a pair of prescription “shades,” or you can order glasses that darken when exposed to bright light.

What additional types of protection should I consider? If you worry about light, including harmful UV, leaking in through sides or top of your sunglasses, wear a broad-brimmed hat to reduce some of this exposure. If you use prescription eyewear to correct your eyesight, you may also want to think about getting a pair of UV-blocking contact lenses in your prescription. These lenses may be worn alongside a non-prescription pair of sunglasses for optimum eye protection.

Why are sunglasses important for eye health?

Sunglasses are essential for protecting your eyes from harmful ultraviolet (UV) radiation, which can cause various eye conditions, including cataracts, macular degeneration, and photokeratitis (sunburn of the cornea). Additionally, sunglasses help reduce glare and improve visibility in bright sunlight, enhancing comfort and safety outdoors.

What are UV rays, and how do they affect the eyes?

UV rays are a form of electromagnetic radiation emitted by the sun. Prolonged exposure to UV radiation can damage the eyes’ delicate structures, leading to conditions such as cataracts, pterygium (growth on the eye’s surface), and certain types of eye cancer. Sunglasses with UV protection block these harmful rays, reducing the risk of eye damage.

What should I look for when choosing sunglasses for UV protection?

When selecting sunglasses for UV protection, look for labels indicating they block 100% of both UVA and UVB rays. Additionally, choose sunglasses that provide adequate coverage, including the eyes, eyelids, and surrounding skin. Polarized lenses can also help reduce glare and improve visual clarity, particularly for outdoor activities like driving or water sports.

Can wearing sunglasses prevent cataracts and other eye conditions?

While wearing sunglasses cannot guarantee the prevention of cataracts or other eye conditions, they can significantly reduce the risk of UV-related damage to the eyes. By blocking harmful UV rays, sunglasses help protect the eyes’ delicate structures, potentially slowing the progression of conditions like cataracts and macular degeneration.

Are expensive sunglasses better than cheaper ones?

The price of sunglasses does not necessarily indicate their level of UV protection or overall quality. While some designer sunglasses may offer superior craftsmanship and style, many affordable options provide adequate UV protection. Focus on selecting sunglasses that offer 100% UV protection and fit comfortably for optimal eye health and comfort.

Can I wear sunglasses with prescription lenses?

Yes, prescription sunglasses are available for individuals who require vision correction. These sunglasses feature prescription lenses tailored to your specific vision needs while providing UV protection and glare reduction. At Clinton Eye Associates, we offer a variety of options for prescription sunglasses to suit your style and preferences.

How often should I wear sunglasses?

It’s recommended to wear sunglasses whenever you are outdoors, particularly during peak sunlight hours (10 a.m. to 4 p.m.) or when participating in activities with high UV exposure, such as skiing, hiking, or spending time at the beach. Even on cloudy days, UV rays can penetrate clouds and cause eye damage, so wearing sunglasses year-round is essential.

Can children benefit from wearing sunglasses?

Yes, children can benefit from wearing sunglasses to protect their developing eyes from UV radiation. UV exposure during childhood increases the risk of eye conditions later in life, so it’s important to instill good sun protection habits early. Look for sunglasses specifically designed for children, with durable frames and 100% UV protection.

How do I ensure proper fit and coverage with sunglasses?

Proper fit and coverage are essential for maximizing eye protection with sunglasses. Choose sunglasses that wrap around the sides of your face to block UV rays from entering the eyes from the sides. Ensure the lenses are large enough to cover the entire eye area, including the eyelids, and sit comfortably on your face without slipping or pinching.
