At Eyeglassdirect.com our Bifocal Flat-Top 28 CR39 Plastic Lenses are manufactured using the same high quality CR39 Plastic material as our standard lenses.  Bifocal Flat-Top 28 provide you with clear, sharp distance and reading vision.

Our standard prescription eyeglasses are fabricated using the highest grade optical quality plastic lenses. Standard plastic, with its high grade optical qualities, can also be tinted darker than polycarbonate. Although standard plastic is not manufactured with UV and scratch resistant coatings, we add these coatings at no additional cost to you.  Recommended for prescriptions from +3.00 to -4.00.
