Traditional Progressive and "Wide View" Free Form.
I have learned that;
There are 2 types of progressive technology on the market. Traditional Progressive and "Wide View" Free Form Progressive.Traditional progressive's view are limited to a channel in the middle of the lens, called field of view. If you look outside the field of view such as edge of the lens, you might see distortion. While "Wide View" progressive has twice as big field of view than traditional progressive, therefore you rarely have any distortion in your viewing area, which makes it more comfortable to wear and easier to adjust to.
Good thing At cheapglasses123.com their "Wide View" Free Form Progressive starts from $89.95.
