How Do Varilux and Crizal Lenses Compare?
Varilux lenses are progressive lenses, which means that they offer both close-up and distance vision correction, but they feature a more gentle transition between the two than traditional bifocals. Crizal lenses reduce glare for clearer vision and ultraviolet protection.
Varilux lenses were the first progressive lenses available on the market. Unlike bifocals, there are not two separate areas of the lens dedicated to close-up and distance vision. Instead, the lenses blend both types of correction to create a more natural field of vision. They are modeled with a computer before being physically manufactured. These lenses are particularly effective for presbyopia, which is the loss of up-close vision as people age and often affects the ability to read.
Crizal lenses reduce the uncomfortable glare around sunlight reflections and bright lights at night often created by eyeglasses, and they reduce glare from digital devices. The thin coating also resists damage from scratches, dust, smudges and water, and it protects the wearer's eyes from ultraviolet light. Crizal lenses are appropriate for vision conditions like presbyopia, myopia (nearsightedness) and astigmatism, which is a distortion of the eye.
Varilux and Crizal lenses are both manufactured by Essilor. Crizal finish can be applied to progressive Varilux lenses to reduce glare.
