What is glaucoma


Our eyes need to be healthy for us to see well.​

Liquid in your eye

Your eye has clear liquid in it.​

This keeps your eye the right shape.​


Glaucoma is a problem with the liquid in your eye.​


The liquid in your eye drains away and is replaced by fresh liquid.

Too much liquid

If the liquid cannot drain away properly, there can be too much liquid in your eye.

Hurt eye

Too much liquid causes pressure. ​

This can damage your eye.

Eye test

Having an eye test every 2 years or more often is important.


The optician will tell you if they need to check for glaucoma.​
