Why should children wear Photochromic (Transitions) Lenses?
Blue light and UV radiation is present in all daylight. Whilst these are an essential component of natural white light, cumulative exposure to these radiations (rays) have a damaging effect on the delicate and sensitive retina at the back of the eyes. In order to minimise long-term damage, these harmful radiations should be filtered out by appropriate means – the best and most convenient being photochromic lenses. These lenses will only darken and absorb harmful rays if exposed to UV radiation and so will remain clear at night or indoors.
Photochromic lenses have come a long way over the last several years. These lenses change more readily and the versions now available in poly-carbonate fade in about half the time of the plastic counterpart. Children seldom will switch from indoor glasses to sunglasses without parental assistance and/or insistence. Since photochromic lenses automatically adjust in proportion to the intensity of the light, they are an excellent choice for children at a time when they are most vulnerable.
Water, sand and cement are significant sources of reflected glare and young children are frequently exposed to all three. Today’s polarised and photochromic lenses block harmful ultraviolet light and can selectively attenuate (filter out) harmful blue light. Since polarised lenses reduce reflected glare, and scatter (Rayleigh Effect) children will suffer less discomfort and their eye will be better protected from damaging blue light.Half term begins today – have their eye tested this week to make sure that they are seeing as well as they should … and consider protecting their eyes from potentially damaging sunlight this Summer
