Lens Types
Single Vision Lenses
Single vision glasses are designed to help people who require correction of farsightedness, nearsightedness, or astigmatism. These eyeglasses have just a single optical prescription correction and they distribute focus evenly over the entire surface area of the lens.
Bifocal Lenses
Bifocal eyeglass lenses contain two lens powers to help you see objects at all distances after you lose the ability to naturally change the focus of your eyes due to age, also known as presbyopia.
Multi-focal Lenses
Multifocal lenses allow you to see at multiple distances, because they have different sections for viewing close up, far away and everything in between. Whether you're driving, using a computer, shopping or reading, you can usually wear one pair of multifocals to accommodate most of your vision needs.
