People With Good Eyesight Do Not Have To Choose Prescription Sunglasses
Patients with refractive errors should choose prescription sunglasses. Prescription sunglasses are specially formulated after optometry based on the refractive status of the wearer. People with good eyesight do not have to choose prescription sunglasses, which are only needed by patients with refractive errors or presbyopia. This lens is not flat light, but can correct nearsightedness, hyperopia, astigmatism, or presbyopia. Because these glasses need to be worn all day, both indoors and outdoors, color changing lenses are used. There is no significant difference in style between prescription sunglasses and non prescription sunglasses, including bifocal lenses, progressive focus lenses, and presbyopia lenses.
Prescription sunglasses can be made from a variety of materials, such as high refractive index materials, polycarbonate, plastic (CR-39), or glass. The first two materials are better and most commonly used.
What eye diseases can be caused by wearing sunglasses improperly? Improper wearing of sunglasses can also cause sunglasses syndrome: After 1-2 weeks of continuous wearing of sunglasses, symptoms such as skin numbness and sensory retardation may appear between the eyes or between the cheeks. When breathing, there may be a feeling of discomfort in the nose, such as having a cold. Some people may also feel small worms crawling on their faces, and their eyes may become sore. This is the manifestation of sunglasses syndrome, which is caused by the fact that they often wear glasses with wide sides, thick frames, and heavy weights.
