UK Contact Lenses

Despite the fact that contact lenses are worn by more than 75 million people worldwide and the majority of these people do not experience any problems, complications can arise.

Problems are normally caused by not looking after your lenses properly. If you do not follow the guidelines given by your optometrist, you risk contracting an infection.

Corneal Ulcers

Corneal Ulcers are contracted by not cleaning contact lenses well enough. You are most likely to get a corneal ulcer if you wear soft lenses or extended wear contact lenses.

Corneal Ulcers are extremely unpleasant and cause acute pain, redness and discharge.

If you think that you might have a corneal ulcer, you should stop wearing your contact lenses immediately and ask your optometrist for advice.

Corneal Oedemas are caused by not getting adequate oxygen to your cornea. In the majority of cases you will not experience any physical symptoms if you have a Corneal Oedema. If you do have physical symptoms you might experience eye pain when you remove their lenses and hazy vision.

Regular eye exams can help detect if there is not enough oxygen reaching your cornea before problems actually occur.
