As we get older, our eyes weaken, and we begin to lose the ability to focus on objects up-close. Reading glasses feature magnifying lenses which enlarge anything in our viewing area, making close range items like text look clearer.
The strength of the lenses, called diopters, will vary based on your age, vision and how you use your glasses. A +1.00 pair indicates a strength of one diopter. Diopter levels usually increase by +0.5 and range from +1.00 to +4.00.
