Reading Glasses - 3 Pairs

With bifocal glasses , all you have to do is put on one pair of glasses and you're good to go all day. The prescription lenses are ready to wear in a variety of strengths, so they are very popular and cost-effective.

Reading glasses are designed to view close objects as reading a book, or viewing a computer screen. Any objects far away will be blurred. The option for you to wear glasses all the time is to use bifocal or progressive lenses . This type of lens provides both a close view (bottom lens) and a far view (center lens).

How do I know what strength reading glasses to get? Optometrists have therefore made some generalizations about the strength of reading glasses needed at certain ages (this may differ if you already have a prescription). 1. Ages 40–49: +0.75 to +1.50 diopters. 2. Ages 50–59: +1.50 to +2.25 diopters. 3. Ages 61 and up: +2.25 to +2.75 diopters.

Typically, most people start needing to use reading glasses at some point to compensate for lost flexibility in and around their eyes. So, when will you need to start using reading glasses? Everyone is different, but most patients get their first pair or readers sometime between the ages of 41-60.

To find the right reading glasses, add the sphere number to the ADD number. Next, look at the cylinder measurement and the axis measurement. Astigmatism is typically not corrected in over-the-counter reading glasses.
