Despite the previous version of the answer, there is no credible evidence at all for radiation from television, cellphones or computers causing either temporary or permanent blindness. Looking at the sun can overwhelm the retinal cells and cause temporary blindness, but may also very easily cause permanent damage. There are a number of causes of temporary blindness, but most temporary blindness results from sudden temporary changes in blood pressure, such as aortic dissection, basilar artery or retinal migraine, cardiac or carotid emboli, choroidal or retinal vascular spasm, hyperviscosity, severe occlusive carotid disease. Stress responses (temporary blindness is sometimes seen in soldiers in conflict) or mild strokes may also have the same effect. Other causes of temporary blindness may result from chemical or biochemical poisons such as Pepper Spray, or plants such as daphne or spurge.
