Eyes and their visual acuity are bound to deteriorate over time. As we grow older, we become more susceptible to developing poor eyesight or other eye problems. While the problems associated with gradual deterioration of eye muscles and nerves are unavoidable in most cases, one can prolong their good eye health by timely investment in eye care when they are young. The fundamental reason to do so is to keep the eyes healthier and safer from damage in the present and the future.
As the eyes are one of the most sensitive parts of the body that serve a vital purpose, caring for them is an important practice we must inculcate in our daily routine. A part of that routine is investing in protective eye gear that shields them from the UV radiation of the sun. Exposure to the sun’s rays has been established as one of the leading reasons for eyesight deterioration, which makes investing in sunglasses and protective eyeglasses even more important. The necessity of the same has led to eyewear products like Photochromic lenses, which are protective and technically equipped to cater to your prescription needs, all at once. Therefore, let us go through everything you need to know about Photochromic lenses.
Photochromic Lenses: The Basics
The operation of photochromic lenses relies on external stimuli. The function of these lenses is protective in nature as they are installed in glasses and prescription glasses to filter out UV radiation. It achieves this protection by slowly changing its shade from clear to dark as a response to the environment it is in. Indoors, the lenses remain clear as they can operate as regular powered lenses but the moment the wearer moves outdoors and is exposed to sunlight, the lenses begin to darken. The photochromic lenses take about 30 seconds to go from clear to tinted (like sunglasses), and 5 minutes for them to return to clear once exposure to sunlight ceases.
As Reactolights
Photochromic lenses are often called reactolights due to their design since they react to the external environment of the wearer to complete their function. Usually made of polycarbonate, plastic, or glass these lenses have small molecules of silver halide and chloride infused into the lens material. The silver halide and chloride then undergo a chemical reaction when they are exposed to sunlight. The chemical reaction causes the molecules to shift and change in size, making the lenses darker and giving them a sunglass tint. Due to the reaction being reversible, the molecules return to their original state once removed from sunlight, making them clear again.
Why go for Photochromic lenses with power?
The basic reason a person might install their eyeglasses with photochromic lenses is that they get to use their eyeglasses for their prescription needs and as a sunglass when outdoors. This makes it a dual-purpose eyewear solution, where protection and function come at a price for one. These lenses are a technical marvel on their own and can help make your life easier in many ways. There are many benefits to investing in photochromic lenses with power, let us take a look.
- Holds off UV Radiation: Prolonged and unfiltered exposure to sunlight is detrimental to eye health, and a person with regular eyeglasses may have to compromise on that front when they move outdoors. Photochromic lenses adapt to that need, turn into sunglasses, and protect your eyes from radiation while functioning as eyeglasses at the same time.
- Cost-Effective: Since photochromic lenses with power can turn into sunglasses when outdoors, you do not have to separately purchase sunglasses. While photochromic lenses may be more expensive than regular lenses, they are still more cost-effective than two separate pieces of eyewear.
- Long-term Eye Health: Protecting your eyes from UV radiation is necessary for those who are conscious of their long-term eye health. Eye problems like cataracts, macular degeneration, and blurred vision are exacerbated by UV radiation. Therefore, investing in photochromic lenses can keep these problems at bay.
