For those new to progressive glasses,often an accommodation period is required because the brain need to adjust itself to work with your progressive glasses, maybe at the beginning, you will feel faint and dizzy, especially when going up and down stairs, the feeling is much more obvious. Don’t be neverous or worry about that, it`s just common case.

Have ordered 7 pairs of prescription glasses for myself and wife through www.cheapglasses123.com. Ordered the slightly thinner prescription lenses the first time, and realized I could save $160 by ordering the standard lens. I compared the standard lens to the so called "high index" lenses from local Optical store and they were about the same thickness. The only difference was I paid an extra $160 for those lenses.
