Major advances in contact lens design mean that almost everyone can wear contact lenses successfully. People of all ages can be fitted, although special care is needed for the very young and elderly. Common eyesight defects, such as short-sight and long-sight, are easily corrected but now conditions such as astigmatism and presbyopia (the need for reading glasses) can also be treated very effectively.
In the past, people with astigmatism, a condition in which the eye is irregularly shaped causing distorted vision, were restricted to wearing spectacles, but today toric soft lenses are available both from stock or manufactured specifically for more complicated prescriptions. Presbyopia is the ageing of the eye’s natural crystalline lens which progressively affects everyone over the age of about 40 and which makes it difficult to shift focus (accommodate) between near and distant objects. This is usually corrected with varifocal contact lenses which provide clear distance and near vision. A second alternative is blended or mono vision, where one eye is corrected for distance and the other for near but success depends on the individual and their ability to adapt to seeing out of one eye at a time.
As contact lenses are worn next to the eye, there is nothing to obstruct your peripheral vision. In addition, the lenses move with your eye, meaning that you are always looking through the centre of the lens, where vision is best. In the majority of cases, people can actually see better with contact lenses than they would with glasses.
Before you can wear contact lenses you must have a full eye exam. At VisionCare Optometry we are fully trained and qualified to fit contact lenses and undertake regular training with our contact lens suppliers to ensure that we are right up to date with their latest developments.
During the examination your eyes will be tested to determine the strength of lenses you need for clear vision and also the health of your eyes and eyelids will be examined. The quality of your tears, needed for lubrication of the contact lens, will also be assessed. Then, the curvature and diameter of the cornea at the front of your eye will be measured, together with the size of your pupils and the position of your eyelids.
Based on this information, our Optometrist will be able to give advice about the most suitable contact lenses.
