There has never been a greater choice of lenses that help to reduce the weight of your spectacles and enhance the appearance. We recommend plastic lenses for most of our patients. They are lighter in weight and safer than glass. Because plastic is a softer material, a scratch resistant coating or hard anti-reflection coating is recommended.
These lenses use flatter curves towards the edge to improve visual performance. Besides improving peripheral vision aspheric lenses are also thinner and lighter. With the flatter lens, reflections can be more noticeable and an anti-reflection coating is advisable to further improve the cosmetic appearance.
This type of lens is particularly useful for those people with higher prescriptions. The material they are made from allows the lens to be made up to 33% thinner than standard lenses. Another benefit is that the lenses are are less likely to chip or break making them suitable for rimless and semi-rimless frames. These lenses tend to reflect more light and generally come with an anti-reflection coating as standard.
Many of our patients play sport and would like wrap-around spectacles. If you put standard lenses into a wrap-around frame the vision, through the lens, tends to be distorted. A sports curved lens overcomes this problem by using a steeper lens design that is individually designed for the frame. However, the prescription range for these lenses is restricted and they are unsuitable for higher powers.
