The light-darkening, or photochromic, lens has a special layer that is activated by UV radiation. It remains transparent indoors and darkens outdoors. Such glasses serve the function of both dioptric glasses and sunglasses.
Tinting the lenses
- Grey lenses provide the most neutral, natural vision in most situations, ideal for use in sunny situations
- The brown shade is perfect for overcast weather or changing light conditions
- The green lens is versatile in colour, blending well with different styles of frames and glasses, giving a trendy look
All three colours have their advantages, but grey is often the preferred colour. Why? Grey lenses have a neutral tint that distorts colour perception less and generally provide a greater degree of darkening, effectively protecting the eye in bright light conditions.
How long can such a lens be used?
Lenses usually work well until the next diopter change. It is important to note, however, that their effectiveness decreases over time, for example, they react more slowly to certain light conditions and do not darken sufficiently. This is why it is worth having your lenses checked every year to avoid any inconvenience.
Who is it recommended for?
For people who wear dioptric glasses and don’t want to walk around with two pairs of glasses all day or have to keep changing them. For those who go in and out of the house, for those who live an active life regardless of the weather and lighting conditions. People with light-sensitive eyes who are easily irritated by UV light.
