What is a Astigmatism?
Astigmatism is the optical term for more than one point of focus. It occurs when the surface of the cornea or crystalline lens is not spherical. Light from an object does not focus exactly on the retina but at two separate points. An astigmatic eye has curves that are steeper in one direction than the other. An example of this could be where the cornea is not spherical and shaped more like a Rugby ball than football – of course this is not noticeable by just looking at someone’s eyes. As a result, the eye is unable to focus a point or object into a sharp focused image on the retina.
What Are the Symptoms?
The symptoms of astigmatism vary from person to person but the majority of sufferers report:
- Eyestrain and discomfort
- Blurred or distorted vision
- Night vision problems
- The need to squint
Act on symptoms when they start so that you can avoid more complicated issues from occurring and to receive an appropriate diagnosis. Astigmatism is not difficult to treat so don’t postpone treatment when you can restore your previous eyesight and comfort with a visit to our office.
What Causes this Condition?
Sometimes astigmatism may develop following an eye injury or eye surgery and sometimes the condition is present from birth. Unlike myths you may have heard, astigmatism isn’t caused or made worse by reading in poor light, sitting too close to the television or squinting.Astigmatism also occurs due to a relatively rare condition called keratoconus in which the cornea becomes progressively thinner and cone-shaped. This results in a large amount of astigmatism, which causes poor vision that cannot be clearly corrected with eyeglasses. People with keratoconus usually need contact lenses for clear vision and eventually may need a corneal transplant.
There are two types of astigmatism, regular and irregular. Irregular astigmatism is often caused by a corneal scar or scattering in the crystalline lens and cannot be corrected by standard prescription lenses, but may be corrected by contact lenses. Regular astigmatism arising from either the cornea or crystalline lens can be corrected by a toric lens.
Optical Masters offers eyeglasses and contact lenses for people suffering from astigmatism. Most often, eyeglasses are the treatment method of choice for people with this condition. Eyeglasses contain a special cylindrical lens prescription that compensates for the astigmatism which offers additional power to targeted parts of the lens. Contact lenses offer you a wider field of vision than glasses will. Standard soft lenses may not be effective in correcting astigmatism so toric soft contact lenses will be prescribed. Rigid gas-permeable contact lenses maintain their regular shape while on the cornea, and can compensate for the cornea’s irregular shape while improving vision. During your examination and consultation, you will work with one of our expert Optical Masters providers to determine which treatment option works best for your needs and lifestyle.
