Choosing the correct lenses to go into your new frame is something your dispensing optician does every working day of his/her life.
Working closely with you, they will identify the best possible solution to the needs of your vision and your pocket.
The simplest form of lens is the single vision lens. As the name suggests, this lens will correct one eyesight problem, e.g. in the case of reading glasses. People who need a vision correction from a relatively young age will also generally only require a single power of lens to correct the problem.
Bifocal lenses incorporate two corrections, separated by a distinct dividing line. These are most commonly used to correct Presbyopia, which is the condition that occurs as we age and the lens of the eye becomes less flexible and therefore unable to focus at close distances.
Varifocal, or progressive lenses are also used to correct Presbyopia, but these lenses have invisible graduated sections in which the two powers merge subtly, also providing help at the 'middle' distance and thus allowing wearers to see clearly at all distances.
First time wearers of Varifocal lenses sometimes need a period of adaptation to allow the eye and brain to 'learn' what is, essentially, a new skill. However, the design and technology of this type of lens is continually progressing, so nowadays this process is much easier than it used to be. The high level of research and testing involved in developing these advances is the main reason for the additional cost of these types of lenses.
Transitions lenses automatically regulate the amount of light reaching your eyes by changing from clear to dark in the presence of sunlight, thereby reducing the strain on your eyes.
Thinner and lighter lenses are produced using special technology which enables stronger prescriptions to be corrected using less material and curvature. While these lenses are more expensive, the benefits for the wearer in terms of weight and cosmetic appearance make them a worthwhile investment.
At Ideal Eyes, we can supply lenses which include a scratch resistant coating, which protects the lens surface from the scratching associated with general wear and tear. Ask about the Forte coating which offers a no-quibble guarantee against scratching.
UV Coating is always worth considering particularly if you spend a lot of time outdoors. The eyes are particularly susceptible to damage from the harmful rays of the sun, which can be a major contributory factor in the development of some eye conditions, such as cataracts.
Anti-reflection coatings are applied to the surface of the lens to reduce the reflections from the front and back. Of the many coatings available on the market, we recommend the Crizal coatings produced by Essilor, our main lens supplier. The Crizal Forte coating is particularly effective and is the first coating ever to come with a no quibble 2 year guarantee.
