Light Colored Sunglasses are More Beneficial for Health
Wearing sunglasses outdoors in summer is also a form of eye protection. However, ophthalmologists emphasize the importance of wearing qualified sunglasses. A pair of qualified sunglasses must be able to block the passage of ultraviolet rays, have good resolution for traffic signals of different colors, and the regular Sunglasses belong to the flat lens series, with the diopter strictly controlled below 0.008 degrees.
An ophthalmologist said that in the outpatient department, she often encounters patients who cry and are afraid of light when wearing sunglasses. They mostly choose red, green, and green sunglasses, which contradict the light colors advocated in medicine. In fact, brown, light green, and other colors are beneficial for the eyes.
Wearing glasses that are too dark in color can put the eyes in a dark room environment, and the pupils of a person's eyes will automatically expand in a dark environment. Long term dilation of the pupils can easily lead to symptoms such as glaucoma; Poor sunglasses can also cause more ultraviolet rays to penetrate into the eyes, which is easy to cause solar Keratitis, corneal endothelial damage, ocular macular discoloration and other diseases; Dark colored glasses reduce the ability of the eyes to distinguish colors, which can lead to color confusion and cause traffic accidents.
In summer, it is recommended to wear sunglasses outdoors as much as possible, but not all situations are suitable. In the shade without sunlight, you can take off your sunglasses and let your eyes rest for a while in natural light.
