For many, the transition from sunny outdoors to dark indoors is a very annoying process, especially if they are wearing glasses. Many people are forced to wear two pairs of glasses, one being their regular prescription eyeglasses for indoors, as well as prescription sunglasses for outdoors. Most usually only pick one option of the two, making it a burden sometimes to transition oftenly from regular glasses to sunglasses. For those who do not want to continuance of this annoyance, they may choose a different option, one that has been praised, as well as criticized, on many occasions. This option is dealt with by using Photochromic lenses, lenses that darken or lighten depending on the exposure of UV light to the person. While this type of lense has appealed to many customers, one must ask themselves, is this Photochromic lense worth purchasing?
Photochromic Lenses are lenses that are placed on a single pair of glasses, which will lighten or darken dependent on your surroundings. They will darken when exposed to sunlight, and will continue to darken unless you are indoors or away from UV light.
Pros Of Using Photochromic Lenses
1. Photochromic lenses are also known as transition lenses due to the transition of clear glasses to sunglasses, due to the amount of UV present to the wearer. Their are several pros that one may find are good enough to purchase the prescription lense. For one, transition lenses generally make it more convenient, as well as affordable, for the customer.
2. You no longer have to worry about keeping two pairs of eyeglasses, which is a huge advantage since it is easy to lose eyeglasses, and it is even harder to find glasses with limited vision. By only worrying of one pair, instead of two, you can find it a little more convenient owning a single pair of glasses that holds dual purpose, instead of two glasses that hold single purposes.
3. Not only are they convenient, by owning one pair of prescription eyeglasses you are cutting down cost of the glasses, as you are only paying for one pair of prescription eyeglasses. Transition lenses are great in providing constant protection from the UV light of the sun, as direct exposure of the UV light to the eye can lead to serious eye damage, sometimes even blindness.
4. By having a tint option with your eyeglasses, you are able to know you are consistently protected by these harmful UV rays, as long as you are wearing the photochromic lenses. Photochromic lenses work with all prescription types, and eyeglasses with these lenses are still able to be modified in order to be comfortable to the wearer of the glasses.
What Are The Cons Of Using Photochromic Lenses?
1. So far, Photochromic lenses may sound perfect for those who are constantly losing one of their two pairs of glasses, or for those who want the ability to own a uniform pair of glasses. While these facts may convince some to buy right away, their are some downfalls you should know about with these types of lenses.
2. For one, while the transition from clear to tinted on the lenses is usually pretty quick (happens around 30 seconds or so, depending on the brand), the transition from tinted to clear is often not. After you go indoors, after being out in the bright sun, you may notice the time of transition from dark lenses to clear lenses is often longer than the original transformation. This could be rather dangerous if you are entering dark or narrow indoors, as this lack of quick transformation could cloud or even blur your vision.
3. Not only is the transformation slower on the latter, but it is often difficult for wearers to enjoy the full benefit of sunglasses when using whilst operating a motor vehicle. Since most cars offer UV protection through windshields, since the eyeglasses are not receiving this UV as a way to trigger the transition, this means the eyeglasses usually fail to transition, or the transition takes very long.
4. Finally, those seeking complete light protection that likens to their extreme sensitivity to bright lights may want to look for stronger lenses, as Photochromic lenses are usually inadequate in blocking complete light from these sensitive eyes. Photochromic lenses, are thus, not recommended for those with extremely high light sensitivity conditions.
Photochromic lenses are suitable for some, while not matched for others, so really it is up to you in deciding if these lenses are worth it, as they are perfect to some customers, while insufficient or inconvenient to others. If you are wanting further advice on what prescription glasses would be best suited for you, as well as your eyesight, you should consult your eye doctor or a local eye specialist, as they usually have the best insight, as well as helpful recommendations that works best with your eyesight.
