Eyeglass Lens Types

Eyeglass Lens Types

The lenses you put in your glasses determine how well you see and how comfortable they are to wear. Purchasing the best lenses for your glasses is not always as easy as it may seem. There are different lens types for your glasses that effect, your distance and focal points. Realize that at Milligan Optical, we are here to help you make the best decision for your eyes.

Single Vision Lenses

Single Vision lenses have one focal point. Like distance glasses, computer glasses, or reading glasses.  Single vision lenses work like a magnifier, you move it in and out to find the best vision. At one point you see the best. People with younger eyes, the crystalline lens in their eye flexes so they can accommodate between distance and far. As we get older that eyes natural lens does not flex as much, causing us to need help reading up close.

Bifocal Lenses

These lenses give you a combination of two focal points, distance and reading, distance and computer, or computer and reading.

Trifocal Lenses

These are similar to a bifocal except they have three focal points.

Progressive Lenses


There are too many types of progressives lenses to list. There are many brands of progressives; some better than others and some more expensive than others. Instead of using brand names like Varilux and Zeiss, we prefer to categorize our lenses by basic progressive, digital progressive, and personalized progressive.

If you are into technology, and want one of the best progressive lens designs, try Younger Optics patented personalized progressive, Camber.

All progressive lenses work basically the same way. They gradually change in power from the top of the lens to the bottom of the lens. Some give a wider, clearer distance vision, some give a larger computer area, some give a wider reading area, and some have a very subtle change from top to bottom.
