Single
Vision
Today
there has never ben a greater choice of lenses that help to reduce
the weight of your specatcles and enhance the appearance. We recomend
plastic lenses for most of our patients. They are lighter and
safer than glass. Because plastic is a softer material, a sctratch
resistant coating or hard anti-reflection coating is recommended.
Aspheric
Lenses
These
lenses use flatter curves towards the edge to improve visual performace.
Besides improving peripeheral vision aspheric lenses are also
thinner and lighter. With the flatter lens, reflections can be
more noticable and an anti-reflection coating is advisable to
further improve the cosmetic appearance. High
Index Lenses
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-reflecton
coating as standard.
Sports
Curved Lenses
Many
of or 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
will overcome this problem by using a steeper lens design that
is indivualy designed for the frame. However, the prescription
range for these lenses is restricted and they are unsuitable for
higher powers.
