Can anyone tell me what are non-prescription glasses?

[Oakville]

If you vision is perfect and you want to wear glasses only for cosmetic,then the non-prescription glasses will meet your needs. Non prescription glasses have no power in the both lenses.They can't be used for correcting your vision problem.

non prescription glasses mean you have perfect eyesight and have no need to correct your vision, that is, you don't have to need corrective lenses.So people wear non prscription glasses only for fashion purpose other than correct vision defects.

Non prescription glasses are popular among people who are pursuing fashion or who needs UV protection and anti- wind protection.
