Contact lenses provide many benefits to wearers worldwide, but there are some risks if not used correctly. Most conditions can be treated by your optometrist if treatment is started quickly, but more serious disorders can lead to ulcers and potentially permanent vision loss.

Some of the more common signs associated with an eye emergency include:

Pain

Blurred vision

Seeing flashes of light

A loss of peripheral vision

A sudden loss of vision in one or both eyes

Redness or swelling in the eyes or eyelids

A foreign object in your eye- you might experience pain, pressure or discomfort, a sensation that something is in your eye, extreme watering, or light sensitivity
