If you have seen television commercials for transition lenses and have been wondering what they really are, this is just the article you should be reading. They may not be the perfect substitute for a pair of sunglasses but they do have many advantages for the user of prescription eyeglasses. We will try to highlight most of these to you as well as tell you how they work.
The name transition is actually a brand name for Photocromic lenses. These could also be known as Reactolite, Graduations or Reactions. The main technology behind all of these is that the lenses darken as you step out in the sun. On a bright and sunny day, transition lenses adjust automatically to the intensity of light and hence, control the amount of light that falls on your eyes. UV rays are blocked a 100% just like it would with a pair of sunglasses. This means you do not have to carry a pair of extra sunglasses when moving outdoors.
The new age transition lenses take only about 30 seconds to go from light to dark depending on the intensity of sunlight outside and then take the same amount of time to get clear again as you step into a building. Another advantage with newer technology is that they are not made of heavy materials anymore. You can get your transitions in standard plastic or the very light Poly Carbonate making them comfortable for the wearer. Shatter proof materials make them a great buy for children as they offer perfect UV protection for their young eyes.
Here are a few more advantages of transition lenses:
- UV rays can cause macular degeneration and cataracts. Transition lenses offer 100% UVA and UVB protection making them as good as the sun block or sunglasses you use for protection.
- Since they adjust automatically to improve contrast and protect your eyes against glare, they are great for reducing eye fatigue and strain.
- They offer a 2-in-1 solution in the sense that you do not have to carry clear eyeglasses and a pair of sunglasses separately anymore.
- The time required for them to get dark according to the intensity of light and to get clear does not exceed 30 seconds.
- If you squint in sunlight, these are the perfect solution to reduce strain on the eyes.
- If you have a medical condition, have had an eye surgery lately, have developed cataracts, take medicines that have ocular side effects or are just highly sensitive to light, transitions are the ideal choice.
- Children’s young eyes receive thrice the UV exposure in a year then adults. Since transition lenses are now available in shatter resistant safe materials, they are a great buy for them.
- If you thought they were a dull pair, think again. Transition lenses are available with all kinds of materials and designs and gray and brown tints making them fashionable as well.
