EYEGLASSES KNOWLEDGE
Glasses are composed of lenses and frames, which can correct various visual problems, including nearsightedness, hyperopia, astigmatism, presbyopia, strabismus, or amblyopia,
1. The basic structure of glasses includes lenses, nose bridge, nose support, pile head, mirror legs, screws, nuts, and locking blocks. 2. Different types of glasses are divided into optical lenses, sunglasses, and special purpose goggles based on their usage
3. During optometry, hyperopia optometry should first provide a degree higher than the customer's hyperopia degree, forming an artificial myopia state, and then gradually reduce the orthoscope, rather than gradually increasing the orthoscope like myopia optometry
In addition, many industry leaders have a misconception that the smaller the diameter of farsightedness lenses, the thinner they become, but the diameter of nearsightedness lenses has no effect on thickness.
