When it becomes hard to read close up without straining your arm to a maximum, it may be time to consider single-vision reading glasses. Reading glasses are prescription glasses that come in various main styles: full frames, which have the whole lens built to the reading prescriptions, and half-eyes, which sit on the nose.
Full reading glasses are the best prescription glasses for those who spend a lot of time focused on close-up information. Everything seems blurry as you stare up across the room through these prescription glasses.
On the other hand, half-eye reading glasses allow you to glance down and through the lenses for close work, and if you need to view in the distance, you may gaze above these prescription glasses.
Tinted reading glasses are another type of prescription glasses that provide UV protection. The bifocal sunglass also has a non-prescription top half for seeing far away and a reading prescription in the bottom half for gazing up close.
Ready-made reading glasses can be obtained at a pharmacy or optical business that specialises in prescription glasses and from a department store. These glasses are reasonably priced and available in a variety of shapes and styles. However, a critical disadvantage of ready-made prescription glasses is that the optical centre of the lenses is the same in both lenses, and the position of the optical centre of the lenses is not tailored for each wearer. In addition, many people do not even have the same in both eyes, and virtually everyone has some myopia correction in their prescriptions.
It is now much easier to obtain custom-made prescription reading glasses. You may go through numerous internet retailers that specialise in glasses, where you can enter your prescription and have your spectacles personalised. These glasses are sold at a discount, and the design and selection are even more diverse than those available at a typical optical store. See here
