A flash burn triggers sore inflammation of the cornea. This occurs if subjected to bright ultraviolet (UV) light. This can be brought about by all forms of UV light, but the usual source is a welding torch.
Flash burns are strikingly the same as a sunburn in the eye and can affect both eyes. The cornea can fix itself within 1-2 days and eventually heals without leaving behind a scar. Nevertheless, if the flash burn is not treated, an infection can develop. In such cases, it can be serious and even lead to loss of vision.

Management
The treatment for a flash burn usually include the following:
- Dilating drops – these are oftentimes used to relax the eye muscles which relieves the pain and allows the eyes to rest and recuperate. The pupils will appear bigger than normal and the effects lasts for several hours to a few days.
- Dressing – the eyes are covered with padded dressing to allow them to rest and heal.
- Antibiotics – the doctor might prescribe antibiotic drops or ointments to be used at home to prevent infection. A mild steroid-based anti-inflammatory drop might also be prescribed.
Self-care measures
- Pain medications such as ibuprofen, paracetamol or codeine can be used. Make sure that the right dosage is taken.
- Avoid using contact lenses until the eyes have healed.
- Wear sunglasses if the eyes are sensitive to light.
- Artificial tears or lubricants can be used to alleviate any discomfort in the eyes.
If required by the doctor, the individual should return for a follow-up appointment.
