Our eyesight is one of our most essential senses however, maintaing our eye health is something that is often overlooked and even taken for granted. On a daily basis we encounter UV rays, eye fatigue, and glare. Transistion lenses help protect us from these. Inorder to grasp the utility of transistion lenses, one first has to understand these phenomenon.
One of the gravest perils that Transistion lenses protect our eyes from are ultraviolet rays or UV rays as they are better known. UV rays are invisible radiation that is emmited by the sun. These rays damage one's eyes, skin, and even hair. UV related eye diseases include cataracts, macular degeneration, pingueculae, and pteryia. There is no way to entirely prevent damage from UV rays but Transition lenses can greatly reduce the exposure to this type of solar radiation.
Glare is an annoyance that we face on a daily basis. Glare is caused by being exposed to too much light. Not only is this distracting but it is also dangerous, especially when driving. Transition lenses cut glare by adjusting the amount of shade based on the ambient lighting thereby providing crisp vision and vivid colors in sunlight.
Transistions are available in every lens materials and type of prescription (distance vision, reading glasses, progressives, and bifocals). Transition lenses darken in about 30 seconds and lighten in about the same amount of time.
