 |
The bifocal is one of the most basic multifocal lens. This lens consists of two prescriptions; usually a distance prescription with a reading addition placed in a lower segment.

It is a multifocal lens commonly prescribed for those suffering from both presbyopia and hypermetropia, a condition whereby, with age, the eye exhibits a progressively diminished ability to focus on near and far objects. The round top lens includes a segment at the lower half of the lens with a prescription for reading (near distance). |
- Photochromic Transition Lens
Photochromic lenses are optical lenses that darken on exposure to specific types of light of sufficient intensity, most commonly ultraviolet (UV) radiation. They are principally used in eyeglasses that are dark in bright sunlight, but clear in low ambient light conditions. They darken significantly within about a minute of exposure to bright light, and take somewhat longer to clear.
|
Lenses that are clear indoors and automatically adjust their level of darkness outdoors depending on the amount of light are called adaptive lenses. These lenses can be appealing to people who move between indoors and outdoors several times a day.
A daptive lenses automatically adjust from clear indoors to dark outdoors. If you wear glasses, you probably understand the routine: one pair for indoors, and a pair of sunglasses for outdoors. So if your day takes you both indoors and out, you’re constantly juggling glasses. |
