Reading glasses
Why are reading glasses a rule rather than an exception?
If you haven't paid your tax to myopia, presbyopia isn't going to spare you once you enter your 40s. You'll start facing problem in reading near first. With the further passage of age into your 50s, even the distant vision will start having problems. You'll be requiring bifocals now. A typical case of presbyopia!
These glasses come in two main styles: full frames, and half-eyes.
Full frames will suit you if you spend a lot of time attending close-up activities. If you try to look up across at a distance through lenses, it all appears blurry.
Half-eye glasses allow you to look down through the lenses for near work, and look up at a distance without them.
