Can anyone tell me what could happen if you burn your eye accidentally?

See below: Thermal burns of the eye are rare because people's faces are so heat sensitive and the eyelids usually prevent sudden exposure. Nevertheless, thermal burns do occasionally occur. It depends on the severity. A mild burn will heal rapidly as the skin of the eye is shed and rapidly regenerates. In more severe cases there can be various degrees of eye damage or blindness. Alkali burns are worse.
