Eye condition
The cornea thins and bulges into a cone shape, usually starting in the teens or twenties. Vision becomes blurred and distorted, and glasses power changes often. Early diagnosis matters because treatment can slow it down.
At a glance
Book a corneal check if your astigmatism keeps increasing or glasses no longer give clear vision. Try not to rub your eyes. Get same-day eye care for sudden pain, redness or a sudden drop in vision.
The doctor decides which you need. Every test is done at the clinic.
