Production Introduction

Ophthalmologists recommend that you must always wear sunglasses to protect your eyes; this is because our eyeball (lens) is very easy to absorb ultraviolet rays, and the damage of ultraviolet rays has two prominent characteristics:

1.The damage of ultraviolet rays will accumulate. Since ultraviolet light is invisible light, it is difficult for people to perceive it intuitively.

3

2.The damage of ultraviolet rays to the eyes is irreversible, that is, irreparable. Such as: cataract surgery can only be replaced by intraocular lenses. Long-term damage to the eye can easily lead to damage to the cornea and retina, clouding of the lens until cataract occurs, resulting in permanent visual damage.

Since the damage of ultraviolet rays to the eyes is invisible, it cannot be felt immediately. If you don’t wear glasses, you don’t feel particularly uncomfortable. It just means that your eyes are not very sensitive to visible light (such as dazzling glare, glare, and reflected light). , and cannot avoid UV damage.

Does the darker the sunglasses, the better the UV blocking effect?

No, the function of the lens to block ultraviolet rays is that it is treated by a special process (adding UV powder) during the manufacturing process, so that the lens can absorb harmful light below 400NM such as ultraviolet rays when the light penetrates. It has nothing to do with the depth of the film.
