There are various types of eyeglasses. Single vision lenses, bifocal, and trifocal lenses are some of them. Multi-focal lenses are used when you need different strengths to see near and far objects. But these usually come with a visible line separating the different lenses.
If this bothers you, and you still need those multi-focal lenses, then you can opt for cheap progressive lenses.
What is a progressive lens?
Progressive lenses, or PAL, are a type of bifocal lens that allows you to see near or far things depending on your eye needs without a bifocal line. Simply put, it’s a corrective lens for distant and close vision without the normal bifocal line.
The lens is designed to provide long-range as well as a short-range vision by gradually transitioning from strength from top to bottom.
Why do we need a progressive lens?
As we grow older, our eyesight weakens. This leads to a need for a lens that allows focusing on both distant and near objects. This condition is called presbyopia. Most individuals compensate for these shortcomings by wearing reading glasses for nearby objects, and single vision glasses otherwise.
These glasses also work well for children who have both nearsightedness and farsightedness.
Cost of progressive lens
These lenses are more expensive than the ordinary bifocal lens. Standard rates for a progressive lens are around $250 and for the bifocal lens is around $105.
The quality of the lens plays a role in whether you can find cheap progressive lenses. You will have to shop around and compare rates before buying one. Eyeglass companies and the region where they are located play a role in price determination.
Progressive lenses are used by people who need glasses for near vision and distant vision. By combining the 2 single vision glasses for these, you can use one pair to see your way around the world.
