[bendable glasses frames]

What is “jump image”? When a bifocal or trifocal wearer's line of sight moves across these lines, images suddenly move, or "jump." Progressive lenses provide a more natural depth of focus than bifocals and trifocals. Because of the advantages progressive eyeglasses become more and more popular among people over age 40. Today’s progressive eyeglasses become more comfortable to wear and more easy to adjust to them.
