Short sightedness (myopia) results in distance objects being blurred. This occurs when the shape of the eye causes light to bend in front of the retina instead of on your retina. (Figure 1) It can develop either gradually or suddenly, and usually runs in families.

Short sightedness can be picked up in a routine eye exam. It cannot be reversed. You can compensate for the blur with glasses, contact lenses or surgery.
People who suffer with short sightedness may complain of:
- Blurry vision when looking at distant objects
- Squinting to see clearer
Others may notice that people with short sightedness
- Persistenly squint
- Sit very close to the TV, movie screen
- Poor hand eye coordination
- Rub his or her eyes frequently
When to get a check up
Most people that are short sighted develop it during adolescence. It is important to check in children especially if either parent is short sighted. A check every 2 years is a good guideline and every year if there is family history.
If you notice any of the symptoms above, it is best to book in with an optometrist.
