This is an inflammation of your eyelids and can make them red, irritated and itchy. It some cases it can lead to burning, soreness or stinging and could develop into ulcers or styes. 

It tends to be worse in the morning when you could find that your eyelids are stuck together.

Blepharitis is a long term condition that can reoccur at any time.

Types

Anterior

Affects the outside front edge of your eyelids and can be caused by staphylococcus bacteria.

Posterior

Also known as Meibornian Gland Dysfunction (MGD) and is caused when something affects the inside rim of your eyelid - just behind your eyelids (that contain the Meibomian gland)

Who is at risk?

 Is more common in people over 50, but it's possible to get it at any age. Basically, as you get older the gland that secretes part of your tears are more easily blocked and the lubricants they contain are reduced. This means your eyes can feel dry and gritty.

How do you know if you have it?

If you experience any of the symptoms above, then mention it to your optometrist, who can spot the signs by looking at your eyelids.
