Compared with traditional single vision glasses, reading glasses with bifocal lenses can offer clear vision for both near and far distances. Thus, bifocal reading glasses are commonly considered as one kind of multifunctional eyeglasses for people who suffer presbyopia. Although those bifocal reading glasses are available for people who suffer presbyopia, not everyone needs to wear them. So, who need wear such reading glasses with bifocal lenses?
Generally speaking, bifocal glasses are specially designed for people who suffer more than one vision problems, so do the bifocal reading glasses. Usually, people who use bifocal reading glasses suffer from both myopia and presbyopia or even other vision problems such as astigmatism. So, if you just suffer only myopia or presbyopia, a pair of prescription glasses or reading glasses with single vision are enough to meet your vision needs.
From the function of the bifocal reading glasses, we know that people who wear bifocal reading glasses suffer both myopia and presbyopia. Thus most of the target customers of bifocal reading glasses must be at least over 40 years, because that people over 40 years are likely to suffer presbyopia caused by aging. So, they need wear reading glasses. If they happen to suffer myopia at the same time, they probably wear bifocal reading glasses for getting vision aids for near and far distance by wearing one pair of eyeglasses. By wearing bifocal reading glasses, they no longer need to take two pairs of eyeglasses and change then frequently for a better vision.
Therefore, please don’t simply think that bifocal reading glasses are an amazing device and wear them randomly. If you just have one vision problems, you’d better wear single vision eyeglasses. Of course, if you suffer more than one vision problems, please don’t hesitate to wear bifocal reading glasses with the guide of the eye doctors.
