Sunglasses are a type of vision care product designed to prevent damage to the eyes caused by strong sunlight. With the improvement of people's material and cultural standards, sunglasses can also serve as a beauty accessory or a unique item to express personal style.
Our eyeballs (lens) are very prone to absorbing ultraviolet (UV) rays, and the damage caused by UV rays to the eyes is invisible. To protect the eyes, it is necessary to wear sunglasses regularly.
Ophthalmologists recommend wearing sunglasses regularly to protect the eyes. This is because our eyeballs (lens) are very prone to absorbing UV rays, and the damage caused by UV rays has two prominent characteristics: 1. UV damage is cumulative. Since ultraviolet rays are invisible, it is difficult for people to intuitively perceive them.
The damage ultraviolet rays cause to the eyes is irreversible, meaning it cannot be repaired. For example, cataract surgery can only replace the clouded lens with an artificial lens. Prolonged exposure to UV rays can easily lead to damage to the cornea and retina, lens opacity, and eventually cause cataracts, resulting in permanent vision impairment.
