Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.
Progressive lenses sometimes are called “no-line bifocals” because they don’t have this visible bifocal line. But progressive lenses have a significantly more advanced multifocal design than bifocals or trifocals.
Premium progressive lenses (such as Varilux lenses) usually provide the best comfort and performance, but there are many other brands as well. Your eye care professional can discuss with you the features and benefits of the latest progressive lenses and help you find the best lenses for your specific needs.
Feature
Indoor
Restore the color of the transparent lens under normal indoor environment and maintain good light transmittance.
Outdoor
Under sunlight, the color of the color-changing lens becomes brown/gray to block ultraviolet rays and protect the eyes.
What are progressive lenses?
Progressive lenses are no-line multifocal eyeglass lenses that look exactly the same as single vision lenses. In other words,
progressive lenses will help you see clearly at all distances without those annoying (and age-defining) “bifocal lines” that are
visible in regular bifocals and trifocals.
