Photochromic glasses have unique characteristics of turning the colour of the photochromic lenses from transparent to dark when exposed to sunlight. This is how you can identify such types of glasses. These glasses are widely used by people who step outside often during the day and have eyesight disorder too.
What are Photochromic glasses?
Photochromic glasses consist of photochromic lenses which combine the benefits of prescription glasses as well as sunglasses lenses. By this, it means that the lens has power strength just like reading glasses, distance glasses or varifocal and at the same time the lenses change colour from clear to dark. So if you have farsightedness, nearsightedness, or presbyopia then you must be using prescription glasses. However, it becomes difficult for people with eyesight disorder to use sunglasses when outside in the scorching sun. This is because they need to switch from one pair of eyeglasses i.e. prescription to sunglasses when they move out and then switch again from sunglasses to prescription glasses when they step inside. Therefore, it is not wrong to say that the photochromic glasses combine the benefits of glasses as well as sunglasses.
How photochromic glasses work?
Photochromic glasses work as soon as they come in contact with the UV rays. When the photochromic lenses are exposed to the ultraviolet rays of the sun, these lenses change colours. The lens then turns from transparent to dark shades of brown, black, or grey as per the brand. This action occurs due to the reaction of the photochromic molecules which start a chemical reaction by absorbing the UV rays and darken. Alternatively, when the darken lenses are taken away from the UV rays, they return to their original shade i.e. transparent. Because the lens tends to change the colour therefore, they are also known as Transition glasses. They are highly effective in not only correcting the eyesight disorder but also provide protection against the harmful sunlight.
Who must use photochromic glasses?
People who wear prescription or non-prescription glasses can wear glasses having photochromic lenses. Those with prescription glasses can wear photochromic glasses so that they do not have to switch to prescription sunglasses when in sun. On the other hand, people who wear non-prescription eyeglasses while working on the computer can also opt for photochromic glasses.
