At Optika we have a variety of off the shelf Reading Glasses available in different styles and colors for both men and women.  Although such glasses are generally considered safe and provide a quick solution to correcting near vision issues, an individual prescription, as determined by an optometrist usually results in better visual correction reducing eye strain and other visual symptoms you may be having. These readers are a one size fits solution and lenses are not centred according to ones pupillary distance.
  In addition both lenses are of the same power and unsuitable for those whose right eye prescription differs from the left eye. These readers do not correct any astigmatism. We always recommend that you have a pair of reading glasses custom made for you, to your prescription. So before using these readers do consult your optometrist.
