Astigmatism

The front surface of the eye – the clear and transparent cornea – is supposed to be perfectly round, like a ping pong ball. Sometimes it is bent, like an egg or football shape. This results in an image which is blurred or distorted, and is called astigmatism. Astigmatism causes blurriness at all times and at all distances. If there is a lot of astigmatism, and if it is present from an early age, the visual system cannot develop in a normal way and AMBLYOPIA (lazy eye) results. Therefore, it is important to have your child’s eyes examined for the first time before the age of 3 years. This is one of the few times that glasses must be worn by a young child in order for his or her eyes to develop normally.

When the shape of the eye is very much distorted resulting in high astigmatism the use of CONTACT LENSES becomes somewhat more complicated. Rigid lenses (Rigid Gas Permeable) can cover the “bent” surface with a spherical one, essentially eliminating the astigmatism. Hybrid lenses like the “SYNERGEYES” lens or the “DUETTE” lens can accomplish the same thing with better comfort: this is because a hybrid lens has a rigid central area and a soft skirt. A third option for correcting high astigmatism is custom designed soft contact lenses.

Many people with high astigmatism are told that they can’t wear contact lenses. In our experience, this is almost never the case. We succeed in fitting even the most difficult cases. SO EVEN IF YOU HAVE HIGH ASTIGMATISM AND WERE TOLD YOU CAN’T WEAR CONTACTS, GIVE US A CALL – WE CAN ALMOST CERTAINLY HELP.
