Sunglasses should hold at least 70% of the light that gets on them. If, for example, they delay 50% of the radiation, then wearing them is absolutely pointless.

Qualitative points should:.

• reduce the intensity of light to comfortable sensations;.

• make it possible to distinguish the traffic light signal;.

• neutralize ultraviolet waves shorter than 230 nm, which can cause conjunctivitis and burn the cornea;.

• reduce the intensity of ultraviolet waves 320-390 nm, which can lead to cataracts;.

• Weaken the harmful effect of the blue range (from 390 to 450 nm), which causes retinal burn and irreversible damage to the photoreceptors, which can lead to blindness.
