• Is it bad to put reading glasses when not needed?

  There are a lot of factors that determine potential harm from wearing reading glasses you don't need or do not match your eyes. Some individuals that wear non-prescribe Creaders often do so using the wrong power. If too much power is used, and used often, it can decrease the person's natural power to focus. At the Dr Lee Eye Center we have many individuals (typically the 44 y/o male) who has worn Cdime-store readers that were too strong and now their eyes focus like a 60 y/o.
  WARNING: CHILDREN SHOULD NEVER USE THESE TYPE OF READERS.
