As soon as a person reaches middle age, it is normal for their eyes to age. Therefore, if they have presbyopia, they should immediately wear glasses. Many people cannot put down their face and do not wear glasses even if they know they have presbyopia. This not only does not do good to their eyes, but also endangers all normal daily life. The frame and lenses are key components of a pair of glasses. What frames and lenses should be selected for reading glasses? Which materials are good?
Presbyopia frames are electronic optical products mainly used to correct the vision of middle-aged and elderly people. Taking into account the age of the wearer, the frames are generally made of metal materials, most of which are made of aviation company material beryllium copper alloy. They have corrosion resistance, wear resistance, and impact resistance twice that of ordinary metal materials, and are over 35% lighter in weight. The buffer block of the mirror frame can be made of materials with good layering, which is good for avoiding skin allergies. In addition, it should be reasonably avoided and lowered. The nose rest can use silicone rubber and integrate the basic principles of integrated human engineering design, in order to perfectly cater to the nasal bridge bone and provide you with a comfortable and squeeze free wearing experience.
Presbyopia lenses are made of epoxy resin, which can effectively filter out ultraviolet light, infrared sensing, and glare. For middle-aged and elderly people, the adjustment and resistance of the eyes are weak. Only by effectively filtering out harmful strong light and protecting vision can they prevent the occurrence of eye diseases such as age-related cataracts and macular degeneration. In addition, the degree of myopia in glaucoma is different from that in the eyes, so there is no need to wear lenses with too high degree of myopia. Little do they know that epoxy resin lenses have better refractive index, transparency, and ability to block glare such as ultraviolet rays compared to other materials of lenses.
