Are transition lenses good for your eyes?

Transition lenses are also called the ‘photochromic lenses’, ‘light adaptive lenses’ and ‘variable tint lenses’. Transition lenses appear clear indoors and turn darker when exposed to the sunlight instantly. The science behind this transition effect is the presence of silver chloride or silver halide molecules in the lenses that are activated against the Ultra Violet rays present in the sun thereby changing the lens colour to a darker shade. In some cases, dyes are used which undergo chemical changes to convert the lenses from clear to a darker shade. The degree of darkness of these intelligent lenses depends upon the variation of UV rays and sunlight.
