There are many signs and symptoms that could indicate you have an eye emergency. These include, but are not limited, to:
- Eye pain
- Light sensitivity
- Flashing lights and floaters
- Sudden loss or change in vision
- Stinging or burning
- Difference in pupil sizes
- Severe headaches
- Double vision
If you have a foreign body in the eye then a visit to an ophthalmologist is warranted. In general, it is not a good idea to pull out a foreign body out of your eye.
In the event of a chemical burn, flush the eye copiously with water immediately, prior to seeking emergency care.
