What is a Multifocal Lens?
If you have more than one vision problem, you may need glasses with multiple lenses. These lenses contain two or more prescriptions for vision correction. Your service provider will discuss your options with you. Options include:
- Bifocal: This lens is the most common type of multifocus. The lens is in two parts. The upper part helps you to see objects in the distance and the lower part allows you to see objects nearby. Bifocal lenses can help people over the age of 40 who suffer from presbyopia, which results in impaired ability to concentrate closely.
- Trifocal: These glasses are two-thirds bi-focal. The third part helps people who have difficulty seeing objects within access.
- Progressive: This type of lens has a rectangular lens, or continuous tilt, between different lens intensities. The lens gradually adjusts its focus when you look at it. It is like a telescope or a three-focus lens with no visible lines on the lens. Some progressive lenses cause more distortion than others. This is because more lens area is used for the transition between different types of lenses. Smaller focus area.
- Computer glasses: These versatile lenses have a special correction for people who need to focus on a computer screen. They help you avoid eye pressure.
