glasses

These are focusing lenses used to improve vision.  There are many options when buying a modern set of glasses. For example, you can have them made with bifocals, trifocals, or even a no-line bifocal called a progressive lens.  Glasses are also available as transitional lenses that darken when exposed to sunlight.
