Dental Protective Glasses. These glasses are designed to protect the wearer's eyes from spray and debris during dental procedures. Some protective glasses feature magnification in the lenses and others are tinted to protect the wearer's eyes from dental lasers and other lights.
There are four common conditions that cause people to need glasses to see clearly. They are myopia, hyperopia, astigmatism, and presbyopia. ... Eyes with myopia or hyperopia are too long or too short for light to be focused directly on the retina. There are many different medical reasons people wear glasses, but the simple answer is that glasses help people see better. Some people wear glasses for reading things that are far away or for driving. Other people only wear glasses when they're doing an up-close activity, like reading, writing, or knitting.
