How can I treat a scratched cornea?

Scratches on your eye can be extremely painful and uncomfortable. It is one of the most common eye injuries in children and teenagers and often occurs with the use of contact lenses or when playing sports.
With a scratched cornea it may feel like there is something in your eye when there is nothing there.Your eye may get red and irritated, produce excessive tears, and be overly sensitive to lights. If your older child wears contact lenses then they should stop wearing them while three is a scratch on the cornea as this could cause further damage or cause an infection to develop.
You should make an appointment with their G.P. or optometrist who will prescribe medicated eye drops if required. Scratched corneas typically clear up within a week and are usually not serious.
