Posted by sere on March 6th, 2020

Sunglasses are a kind of vision health products to prevent human eyes from being strongly stimulated by sunlight. With the improvement of people's material and cultural level, sunglasses can also be used as special accessories for beauty or personal style.

Our eyeballs (crystals) absorb ultraviolet light very easily. The damage of ultraviolet rays to the eyes is invisible. To protect the eyes, we must always wear sunglasses.

Reasons for wearing sunglasses

Ophthalmologists recommend that sunglasses must be worn frequently to protect the eyes; this is because our eyeballs (lenses) absorb UV rays very easily, and UV rays have two prominent characteristics:

1. Damage from ultraviolet rays can accumulate. Since ultraviolet light is invisible, it is difficult for people to feel it intuitively.

2, UV damage to the eyes is irreversible, that is, irreparable. Such as: cataract surgery can only be replaced by artificial lenses. Long-term invasion of the eyes can easily cause damage to the cornea and the retina, and the lens becomes cloudy until cataracts are induced, resulting in permanent vision damage.

Because UV rays are invisible to the eyes, they ca n’t be felt immediately. It ’s not particularly uncomfortable if you do n’t wear glasses. It just means that your eyes are not very sensitive to visible light (such as glare, glare, reflected light). , Can not avoid the damage of ultraviolet rays.

Benefits of polarized sunglasses

When light is reflected from the surface of an object, it has been partially polarized to produce glare. The opposite effect of glare enhances brightness and reduces color saturation; blurs the outline of objects, makes eyes tired and uncomfortable. Polarizers are made according to the principle of polarization of light, and have a unique limited glare-removing function, making the vision more clear and natural, and have special effects for the driver, which can improve vision and increase driving pleasure.
