Progressive Lenses | No Line Bifocals

https://www.framesdirect.com/shop-by-... What are progressive lenses? Progressive lenses—also called no-line bifocals—are a high-tech solution for the diminished ability to focus on close-up objects that comes with age. The term for this loss of visual acuity is presbyopia, and it usually begins after adults turn 40. Many eye doctors recommend progressive lenses to replace multiple sets of glasses for reading and distance vision. Progressive lenses offer a smooth transition from distance vision through intermediate vision to near vision, and they supply all the in-between corrections as well. This means that instead of having just two different viewing zones (near and distant), like with bifocals, progressive lenses have progressive powers of correction (from bottom to top), easing eye strain and providing the most natural vision correction. We started offering progressive lenses in 1999. Dr. Guy Hodgson, co-founder of FramesDirect.com, has developed a proprietary mathematical method of determining the optimal position of the reading (or seg height) of a progressive no-line bifocal. Should your eye doctor prescribe a bifocal lens, we have the latest lens options available to you. Progressive lenses have gone through several phases of technological advances to perfect the design. The progressive lenses today are more like your natural vision than ever before. You have continual power through out the lens for your reading and intermediate areas. A progressive lens is a great option and removes the unsightly lines of traditional bifocals.
