Enjoying a beautiful day outdoors while wearing prescription glasses can be tough. While you need your glasses to be able to see, you also need to wear sunglasses to protect your eyes from the sun. With a simple visit to the eye doctor, you can turn your favorite shades into prescription sunglasses that will protect your eyes from the sun and also correct your vision. Before you call the Optometrist, there are a few things to keep in mind.
When selecting prescription sunglasses lens, be mindful of the lifestyle questions asked by the optician. These questions are important because certain lens colors are beneficial for different activities. For example, golfers tend to prefer brown lenses because they brighten up the golf course.
You may be presented with the option of polarized or non-polarized lenses. While polarized lenses have been popular among fishermen and boaters because they reduce glare from the sun’s rays on the water, polarized lenses are also important for any outdoor enthusiast since they offer glare reduction and better vision clarity. Some lenses, like Xperio UV polarized lenses, are measured by E-SPF®, the Eye-Sun Protection Factor, a simple index that ranges from zero to 50 in polarized sunglass lenses (and zero to 25 for every day, clear lenses). The E-SPF rating is similar to the SPF number commonly included in suntan lotion. Xperio UV lenses offer protection of E-SPF 50.
When purchasing a new pair of prescription sunglasses, it’s important to consider the frames you choose and how your prescription strength can affect them. Certain factors like thick lenses or progressive lenses can change the way frames fit your face. Consider these facts when selecting frames:
- Wraparound – If you need progressive lenses and/or corrective lenses with a high minus power to correct myopia, you should stay away from wrap frames as they can cause distortion in these types of lenses.
- Aviator – A strong prescription requires thicker lenses. When lenses get too thick, they can keep the temples of an aviator frame from folding.
- Metal – Sometimes a thicker lens can start to pull away from the metal edging of sunglasses frames, especially if there isn’t any metal on the backside of the frame.
- Oversized – If you need a strong prescription, it’s best to stay away from oversized sunglass frames. Oversized sunglasses require lenses with greater surface area. This can cause thick lenses to become too heavy and weigh down the sunglasses.
- High Bridge – The weight of a thick lens in sunglass frames that feature a high bridge or nosepiece will cause the frame to not sit properly on the nose and leave indention marks on the sides of the nose.
