Sunglasses Beauty or Personal Style

1. Sunglasses: vision products to prevent the sunlight from causing damage to human eyes Sunglasses are a kind of vision health care product to prevent eye injury caused by strong stimulation of sunlight. With the improvement of people's material and cultural level, sunglasses can also be used as special ornaments for beauty or personal style. Our eyes (lenses) very easy to absorb ultraviolet rays. The damage of ultraviolet rays to the eyes is invisible. To protect the eyes, we must always wear sunglasses. Ophthalmologists suggest that sunglasses should be worn frequently to protect the eyes; This is because our eyes (lenses) very easy to absorb ultraviolet rays, and the damage of ultraviolet rays has two prominent characteristics: 1. The damage of ultraviolet rays will accumulate. Because ultraviolet light is invisible, it is difficult for people to feel it directly. 2. The damage of ultraviolet rays to the eyes is irreversible and irreparable. For example, cataract surgery can only be replaced by an intraocular lens. The long-term invasion of the eye by it is easy to cause damage to the cornea and retina, and the lens is turbid until it causes cataracts, leading to permanent visual impairment. Because the damage of ultraviolet rays to the eyes is invisible and can't be felt immediately, you don't feel particularly uncomfortable without glasses at ordinary times, it just means that your eyes are not very sensitive to visible light (such as glare, glare, reflected light), and can't avoid the damage of ultraviolet rays.
