non-prescription sunglasses

Everybody loves wearing sunglasses — and most people wear non-prescription sunglasses. Aso called “plano” sunglasses they are sunglasses that contain no lens powers to correct vision problems. As their name suggests, you do not need a prescription from an eye doctor to purchase non-prescription sunglasses. And plano sunglasses are sold everywhere — from doctors’ offices to high-end boutiques to gas stations. Prices can range from extremely affordable to extravagantly expensive, depending on features, materials, and whether they are generic sunglasses or designer sunglasses. Choices of non-prescription sunglass frames and lenses are nearly limitless.

Non-prescription Sunglasses When You Need Vision Correction

Many people who have nearsightedness, farsightedness, or astigmatism choose to correct their vision with contact lenses and wear plano sunglasses with their contacts. The alternative is to wear prescription sunglasses rather than contact lenses and plano sunglasses. If you need vision correction and you find a pair of non-prescription sunglasses you really like, there’s a good chance we can replace the “plano” lenses with prescription lenses of the same color.

Essential Features

No matter where you choose to buy plano sunglasses, it’s important to purchase only sunglasses that block 100 percent of the sun’s harmful ultraviolet (UV) rays. Overexposure to UV rays can lead to serious eye problems over time, including permanent sun damage to the front surface of the eye (cornea), cataracts, and even certain cancers.

The amount of UV protection non-prescription sunglasses provides has nothing to do with the color or density (darkness) of the lenses. UV radiation is invisible and is not significantly impacted by lens tints. It’s the lens material and coatings on sunglass lenses that block UV rays. Most good-quality plano sunglasses will have a label or tag attached to the lenses that indicates the level of UV protection the sunglasses provide. If you’re not sure how much UV protection your plano lenses provide, bring them to us  to be analyzed. If your sunglasses don’t provide sufficient protection, we often can order new lenses that will provide 100 percent UV protection.

Enhancements

For even greater comfort when wearing non-prescription sunglasses, look for styles that feature anti-reflective coating on the back surface of the lenses. This will eliminate glare from light reflecting off the back of the lenses when the sun is behind you. Another option is to purchase plano sunglasses with photochromic lenses that are clear indoors and automatically darken outdoors in sunlight. These lenses are available at our office. Just ask us to show you a demo of these sun-activated tinted lenses.

And if you want the best protection from glare caused by light reflections, purchase plano sunglasses with polarized lenses. These lenses have a special filter in the lens material that eliminates extremely bright reflections of light from water and smooth, shiny surfaces (like automobile windshields). Polarized lenses reduce eye strain outdoors and are especially beneficial for seeing beneath the surface of bodies of water when boating or fishing.

Have an eye exam first

Before purchasing non-prescription sunglasses, schedule an eye exam with us. Even though you may see well enough to pass a driver’s vision screening without glasses, you might be able to see significantly better with prescription sunglasses. Only your eye doctor knows for sure.
