Don’t know your multifocals from your bifocals? Wondering about different lens technologies? Confused by jargon?
Here’s a quick guide to some of the most common lens types:
A Quick Guide to Common Lens Types
Single vision stock lenses have a single-focus power throughout the lens. They are prescribed to correct long-sightedness, short-sightedness, astigmatism and presbyopia (the loss of the ability to focus for reading, from middle-age onwards).
Single vision grind lenses are specially-ground to your prescription if it is outside the range of stock lenses. Our grind lenses are made with “optimised” or “enhanced” optics. This technology results in thinner lenses with larger central optic zones and less peripheral distortion.
Extended focus lenses are a type of versatile lens which extends the range of focus from reading distance to a length approximately the distance of a desktop computer screen. Also known as “desk lenses”, “anti-fatigue lenses” or “enhanced readers”.
Bifocal lenses have two focus powers, separated by a line on the lens. The upper area provides correction for general and distance vision while the lower area adds extra focusing strength for reading and close focus.
Multifocal lenses are the modern version of bifocals. The lens gradually grades in focus so there is no distinct line across the lens, for better appearance with less interference. Also known as “graduated” or “progressive” lenses, they provide focus for long distances, arm’s length tasks and reading.
We only use the latest digitally-based lens designs for superior optics. Our highly-trained staff will evaluate your visual needs and prescribe the optimal lens design for your individual circumstances.
