In strong sunlight or windy weather, people always like to wear sunglasses when going out. In addition to protecting against ultraviolet rays and wind, many people also regard sunglasses as a fashion item to create a stylish look. However, not everyone is suitable for wearing sunglasses. Wearing sunglasses for a long time or wearing inappropriate sunglasses may cause damage to the eyes! Choosing the right sunglasses is very important. Sunglasses are not the darker the better When choosing sunglasses, some people think that the darker the color of the sunglasses, the better the effect of blocking ultraviolet rays. In fact, the main thing to consider when choosing sunglasses is the UV index. Only when the UV index reaches UV400 or above can it effectively prevent ultraviolet rays from damaging the eyes. Some cheap sunglasses are dark in color but cannot block ultraviolet rays. Glaucoma patients should be careful when wearing sunglasses! After wearing sunglasses, the visible light entering the eye is reduced, which is equivalent to being in a dim environment. At this time, the pupil is prone to dilation. If this continues for a long time, it may cause the angle of the chamber to close, causing the aqueous humor to fill up, and the intraocular pressure to rise sharply in a short period of time, thereby triggering an acute attack of angle-closure glaucoma . Children should be careful when wearing sunglasses! Since children's visual function is not yet mature, wearing sunglasses for too long will affect the further development of vision and even cause amblyopia . Therefore, it is not suitable for younger children to wear sunglasses. Director Li Fuhua of Tianjin University Aier Eye Hospital said that wearing sunglasses for too long or wearing low-quality sunglasses for a long time is not only not good for the eyes but also increases the burden on the eyes and easily causes visual fatigue. Glaucoma patients should try to avoid wearing sunglasses and using their eyes in dim environments for a long time to prevent acute glaucoma attacks. |
