Actually, they are almost the same price, sometimes, progressive lenses are more expensive than bifocal lenses, but not too much.

At the online optical store PrescriptionGlassesOnline.net, the bifocal lenses are cheaper than progressive lenses.
Standard (1.50) Bi-Focal Lenses only cost you USD24.60.
Thin and Lite (1.57) Progressive Lenses only cost you USD38.15.

Hi, Ashton. I think progressive glasses are more expensive than bifocal glasses. just like Kellysprings said. Bifocal lenses only cost %24.60. but wearing progressive glasses is more comfortable than bifocal. Progressive spectacles are a special solution to the people who have both nearsightedness and presbyopia. Unlike a bifocal lens or a trifocal lens, a progressive lens can offer progressive and natural vision correction.
