Spectacle prescriptions
can be broken down into three main types:
Single vision lenses Most common in use with clients below 40-45 years of age, these tend to be the standard type of lens fitted.
Bifocal lenses tend to be supplied to older clients who require a single solution for both close work and distance.
Progressive lenses are a very sophisticated lens type which combines near and distance vision requirements into a single lens (with no visible line).
All lens types can benefit from a range of surface treatments which are applied before the lens is fitted into the chosen frame. This can include anti-scratch coatings, anti-reflection coatings and tints.
In addition, there are specific types of lenses which offer particular benefits and opportunities including: impact-resistant lenses (for sport or work-related activities); UV lenses (to reduce glare); polarised lenses (for sunglasses) and lenses that adjust automatically to sunlight and lower light conditions.
