Myopia, or short sightedness, is caused when the eye is longer or the crystalline lens is stronger than normal. This causes light rays to be focused to a point in front of the retina, making distant objects appeared blurred whilst near objects are clearer. Placing a minus or concave lens in front of the eye pushes the focal point back onto the retina.
Eyes needing higher myopic correction are more at risk of developing serious conditions such as retinal detachment or glaucoma.
Myopia usually starts to show in children aged 6-13 years old, but can also develop in adults too.
Signs to look out for include:
- difficulty reading words from a distance, such as reading the whiteboard at school
- sitting close to the TV or computer, or holding a mobile phone or tablet close to the face
- getting headaches
- rubbing the eyes a lot
Short-sightedness often runs in families, so you may have relatives who are also short-sighted.
It can get worse until the eye has stopped growing, at around 20 years of age.
