Additionally, it is not recommended for the elderly to wear sunglasses as they may pose a danger due to dim lighting. On the contrary, some people must wear: artificial lenses placed after cataract surgery, pupils dilated due to certain eye diseases, people engaged in skiing or mountain exploration sports, and drivers. To reduce the damage of ultraviolet rays to the eyes, it is best to wear sunglasses.
2.Can myopia and sunglasses coexist?
Patients with myopia need to consider their refractive power when choosing sunglasses. For low or moderate myopia, they can wear regular sunglasses without affecting safety, while for high myopia (above 600 degrees), they need to wear sunglasses with refractive power for safety.
3.What is the primary consideration when choosing sunglasses?
Sunglasses should be selected based on their functions, which can be divided into polarizing glasses, sunshades, and sports glasses according to their functions.
Polarizing glasses: Drivers and fishing enthusiasts are recommended to choose polarizing glasses, which can eliminate glare from all directions and make objects look clearer.
Blackout lens: The blackout lens can selectively filter harmful blue light and ultraviolet light, while allowing other visible light to pass through the lens as much as possible. It is suitable for patients with macular degeneration, diabetes eye disease, and excimer surgery.
Sports goggles: The frames of sports goggles are specially designed, suitable for skiing and mountaineering enthusiasts.
Before wearing sunglasses, it is recommended that the general public consult a professional ophthalmologist and choose sunglasses with UV protection labels to avoid unnecessary harm.
4.What color sunglasses are most suitable for oneself?
The lenses come in a variety of colors, and considering eye health, medium depth shades of gray and brown are the best. The selection of lens color should be based on the principle of not distorting the color of the surrounding environment, having clear edges of objects, and being able to effectively identify signal lights of different colors.
Gray lenses can evenly absorb any color spectrum, and the scenery seen after wearing the lenses will only darken without significant color difference; Tea colored lenses can filter out a large amount of blue light, improve visual contrast and clarity, and have a good wearing effect in severe air pollution or foggy conditions.
The color of the glasses worn by the driver should not be too dark, otherwise it will delay the transmission of visual signals to the brain, cause distortion of speed perception, and make the driver make incorrect judgments. It is recommended to wear a pair of brown sunglasses.
