Types of Progressive Lenses
At the same time, there are different types of progressive lenses and they are standard PALs, short corridor PALs, computer PALs, and Reading PALs.
Standard PALs must fit your vision needs. They can be added to frames of your choice, but you need to ensure that the frames are the right width and height proportions to grant enough space for the gradient changes in the lens.
Short corridor PALs are made to fit into smaller frames so as to suit a wider range of eyewear styles.
Computer PALs are designed for computer users and other occupations that require strong intermediate and distance vision.
Reading PALs are designed for those who enjoy reading and they can opt for a pair of lenses with a larger close vision zone.
Each frame is an extension of your personality. Use your favorite frame to give you the ideal vision. There are a variety of lenses that fit any prescription, including progressive ones. Gainesville Opticians provides a customized collection of frames and styles from brands we know, trust, and love.
The frames should be the right size.
When choosing glasses for kids, pay attention to the size of the frame. Be careful not to choose frames that are too big for your child, and avoid frames that will create shadows or blind corners.

Sunglasses made of celluloid were sold on the beach of Grand West, New Jersey, and became very popular.
