Sunglasses are not just the finishing touch to your stylish outfit; they serve a much more important function: protecting your eyes from the harmful effects of the sun. While glare can make it hard to see, the UV rays reflected by the sun pose a serious risk to both your eyes and your vision. The right pair of sunglasses should offer superior protection, a comfortable fit, and enhance your vision. Here are some key factors to consider when choosing your next pair of shades.

UV Protection

UV radiation comes in two forms: UVA and UVB. While UVA rays are less intense, they are more widespread, accounting for 95% of the UV radiation reaching the Earth’s surface. These rays are linked to skin cancer, premature aging, and cataracts. On the other hand, UVB rays are even more dangerous to the eyes and are the primary cause of sunburns and skin cancer. These rays are especially potent in the summer months, particularly between 10 AM and 4 PM, and can even reflect off surfaces like snow, water, and concrete.

The harmful effects of UV rays are cumulative, meaning the damage builds up over time and is irreversible. This makes it crucial to start wearing sunglasses at an early age, especially since younger eyes are more sensitive. When shopping for sunglasses, make sure they block out 100% of both UVA and UVB rays, as this is the most important consideration for eye protection.

In extreme cases of UV exposure, a condition called keratitis can occur, essentially causing a sunburn on your eye. This can result in temporary vision loss and intense discomfort hours after sun exposure.

Sunglass Lens Options

Once you’ve secured a pair with proper UV protection, you can explore additional lens options that may suit your needs.

Polarized Lenses:

These lenses are excellent for reducing glare caused by reflections from water, snow, sand, or glass. If you enjoy water sports like boating or fishing, or snow activities like skiing, polarized lenses can be a game-changer. They’re also great for driving, as they minimize glare, offering a more comfortable driving experience and clearer road vision.

Tinted Lenses:

Certain lens tints can improve comfort and visibility in specific environments, but it’s important to choose wisely. While some tints enhance contrast, others may reduce vision clarity or even worsen it by causing pupil dilation, which increases UV exposure. Opt for lenses with a moderate tint that doesn’t distort your vision. Your optometrist can recommend tints based on your lifestyle or specific activities, like golfing or fishing.

Photochromic Lenses:

Photochromic lenses automatically darken when exposed to UV light, providing convenience for those who wear prescription glasses. These lenses adjust as you move between indoor and outdoor environments, ensuring optimal comfort and protection.

Lens Materials

There are several lens material options, including polycarbonate, acetate, Trivex, and glass. The choice of material affects durability, clarity, and cost. Be sure to test a few materials to find the one that offers the best combination of features for your needs.

Sunglass Frames

Frame Size:

A well-fitting frame is crucial for both comfort and adequate protection. Ensure the frames fit your face comfortably and provide sufficient coverage for your eyes. When trying them on, check that they feel secure around your temples and bridge and don’t slip off when you look down.

Frame Materials:

Sunglass frames come in a variety of materials, each with different strengths, weights, and comfort levels. Choosing a frame material that aligns with both your lifestyle and fashion preferences is essential for a functional and comfortable pair of sunglasses.

Making the Purchase

When buying sunglasses, it’s worth checking if your vision insurance covers the cost when purchased through an optometrist’s office, as opposed to a retail or sports store. An optician can also help you find the perfect pair, taking into account your vision needs and style preferences.

The wide range of brands, styles, and materials available means you don’t have to compromise on protection, comfort, or style when selecting your next pair of sunglasses. Your eyes deserve the best, so make sure you choose sunglasses that provide top-notch protection, fit, and comfort.
