1, lens material: can be divided into glass, resin and polycarbonate (PC) three, three materials of the lens have their advantages and disadvantages. (1) the advantages of glass lenses: cheap, good transmittance, surface cut resistance; its disadvantage is easy to break, heavy weight (2) the advantages of resin lenses: light, impact resistance, not easy to break; disadvantages are the surface is soft, not cut resistance, more expensive, thicker. (3) Polycarbonate lenses are commonly known as space lenses, PC lenses for short, with the following advantages: impact resistance, light weight, medium thickness, good impact resistance; disadvantages are high price, lack of scratch resistance, and low dispersion coefficient. Amblyopic children have poor visual acuity, poor visual function, weak color recognition, poor contrast sensitivity, and polycarbonate lenses are prohibited in the dispensing process. 2, progressive multifocal lenses: for a pair of glasses that can see both far and near and can see medium distance objects, in recent years in the domestic development and popularity of the state. Deputy Director Song Xin said: Adolescents use regulation when reading at close range, and long time use of regulation will produce regulation spasm, causing the growth of the eye axis, which makes myopia occur, and with further long time reading work, making myopia deepen. Based on this theory, it is possible to prevent the occurrence of myopia and control the development of myopia in children by using the method of near reading with additional farsightedness and hyperopia. It is particularly suitable for refractive error states: monovision ≤ ± 6.00DS, astigmatism ≤ ± 2.00DC, refractive aberration ≤ ± 2.00D. Progressive multifocal lenses are divided into three main categories according to the eye usage and physiological characteristics of different age groups: (1) Myopia control lenses for adolescents: they are used to reduce visual fatigue and control the rate of myopia development. (2) Adult anti-fatigue lenses: used for teachers, doctors, people with too much close and computer use to reduce visual fatigue from work. (3) Progressive lenses for middle-aged and elderly: used for the correction of middle-aged and elderly presbyopia, a pair of glasses to easily see far and near. It should be emphasized that children’s glasses are medical supplies for the correction of strabismus, amblyopia and refractive error. When a pair of qualified glasses is delivered, parents and children should be confirmed the prescription of the glasses and explained how to wear the glasses and the daily maintenance of the glasses, and parents should be reminded to make regular follow-up visits, which should be shortened to two weeks when possible, and the glasses should be cleaned, tested and calibrated at each follow-up visit.
