The main biological effects of IR-A radiation are infrared cataracts and flash burns to the cornea due to temperature rise in the tissue. But IR-A radiation wavelengths are close to the visible light wavelengths and are transmitted to a small extent to the retina; permanent retinal damage can occur if exposure is prolonged. As wavelengths increase into the IR-B and IR-C regions the radiation is no longer transmitted to the retina but corneal flash burn injuries can still be caused.” – University of Warwick, Health and Safety Department
