Hyperopia is a kind of eye disease comes up with the growth of age. Some people who may have a clear history of any vision problem could be suffered by it when they are old. Someday, if one idea occurs to you that you are more and more in need of stretching your arms to the limit of reading morning magazine or newspapers. Perhaps, it is time to prepare a pair of special reading eyeglasses, usually, there are two types of them, single vision and bifocals. The former one is the best choice who hasn’t been suffered from myopia ever; while the bifocals are for the rest ones, and they were first designed by Ben Franklin, who is one of the greatest scientists of the United States!
Usually, people who need single vision reading eyeglasses don’t have to wear them all day long, as such patients may don’t have any problem vision their distance view, they just want them for reading stuffs in front of their eyes, and if you try to look up or into the sky through these lenses, you will feel blurry. When buy them, I want to remind you that you should buy custom-made reading glasses instead of pre-made ones, though the later kind may have many advantages, including cheap price and convenience achieving. But as they are not made accurately to your prescription, some customers may dizzy or even sick after long time wearing.
Actually, today there are more and more people have the vision problem of both myopia and hyperopia, and it is really a trouble to prepare two pairs of glasses when you are out, and switch them at different circumstances. That’s the reason why our manufactures today designs multi-focal eyeglasses for us, the upper part of such lens is for distance vision and the lower is for reading. There are usually two types of them, progressive and bifocal styles! The first kind provides a graduated range of vision from distance to near without a line, and it is also called “no-line bifocals”, there is a transition area between the two focal points, and people who first want to wear multi-focal lenses are usually suggest to wear such progressive ones, as they are more likely to the usual single vision ones.
