The eye is the organ of sight designed for the detection of light. Radiation outside the visible spectrum is harmful to the all layers of the eyelids and eyeball. Ultraviolet light in particular is linked to a number of ophthalmohelioses which impacts patients vision and health . Pterygium, cata- ract, age related macular degeneration and ocular melanoma have UV light implicated in their aetiology. The presentation will outline current research into these conditions and the mechanisms which the eye protects itself from UV light damage. Research has shown possible harmful retinal effects of blue visible light also and this has had impact on the design of intraocular lenses, sunglasses and contact lenses to protect against both UV and blue light. UV lasers have for many years been used to shape the cornea to correct refractive errors. Recently, as in the treatment of some skin conditions, UV light has shown a therapeutic benefi t for the treatment of corneal diseases. Patients with keratoconus, common in atopic patients, can have their corneal ectasia halted with UV-A light and ribofl avin eyedrops in a procedure termed collagen cross linking
