Prescription Sunglasses or Transition Lenses?
People who wear prescription eyeglasses have greater flexibility and more choices than ever before. Consider the subject of sunglasses. In the past, opting for a second pair of prescription sunglasses was really the only way you could simultaneously maintain clear vision and shield your eyes from the effects of the sun. This option is still available and may, for a variety of reasons, be the best choice for you. But since the advent of Transition lenses, buying a second pair is no longer the only choice open to you.
So which one would work best in your particular case? Let’s weigh the pros and cons of both prescription sunglasses and Transition lenses.
The Best Choice: Prescription Sunglasses vs. Transitions Lenses
Transition, or photochromic, lenses feature some obvious advantages. They’re clear lenses that automatically darken when exposed to ultraviolet (UV) light, such as that cast off by the sun. This means your regular eyeglasses will essentially transform into sunglasses in the presence of sunlight, and revert back to clear lenses when sunlight is absent.
With photochromic lenses you’ll only have to purchase one pair of prescription eyeglasses to get both standard eyewear and sunglasses. This keeps your cost down and offers the convenience of a single pair of glasses – no searching around for lost sunglasses, no eyewear left at home or in the car when you need it. Your sunglasses will always be with you…ready to automatically appear when you need them.
With this kind of technology readily available, you may wonder why photochromic lenses haven’t rendered a second set of prescription sunglasses obsolete. The reasons involve personal preference as well as some limitations innate to Transition eyewear.
To begin with, some people prefer a separate set of sunglasses for reasons of fashion. Their sunglasses can be radically different from their regular eyewear frames in terms of style or color, allowing for a change of pace. Also, photochromic lenses will only darken to a certain degree, blocking out about 75% light at their maximum; prescription sunglasses can block as much as 85% of incoming light. Transition lenses may simply not be dark enough for some.
Additionally, Transition lenses will not fully darken without the presence of UV light, a factor that often comes into play while driving. Most automobile windshields are designed to block UV rays, so the full potential of photochromic eyewear is not triggered when used inside a vehicle. If you prefer to drive with a fairly dark set of sunglasses, you may lean towards the option of prescription sunglasses.
