What is the main disadvantage of reading glasses?

• A. Distance objects will be blurry
• B. They may cause eye strain
• C. They are heavier than distance glasses
• D. They correct color perception

Answer: (A)

Reading glasses are designed to help you focus on close work by using convex lenses with a near-focus power. When you look at distant objects through those same lenses, the light is not bent correctly for distance, so far-away items appear blurred. That mismatch between the lens design and the distance demand is the main drawback of reading glasses. They don’t inherently weigh more than distance glasses, and they don’t affect color perception. If you try to use them for distance, you might experience some eye strain from the improper focus, but the central issue remains the blur of distant vision.
