Astigmatism is a condition where the cornea (transparent layer covering the coloured part of the eye) is oval instead of perfectly round. This irregular curve means that light rays entering your eye focus in two different places on the light-sensitive tissue (retina) at the back of your eye. The brain has difficulties interpreting this hence a blurred image is created.
- Distorted vision
- Difficulty distinguishing between O and C, H and N
- Headaches, usually on the front or sides of the head
- Feeling sleepy when you’ve been reading for a while
- Skipping lines when you read
- Sore, tired eyes when performing tasks that require concentration
- Difficulty driving at night, due to both poor vision and glare sensitivity
Spectacles and Contact lenses can be used to correct astigmatism.
