Looking directly at the sun, particularly during a solar eclipse, poses severe risks of photic retinopathy and permanent vision damage due to intense solar radiation.
Papers [5], [8], [9], [10], and [11] all directly examine solar retinopathy or solar maculopathy resulting from unprotected sun viewing, establishing that direct exposure to solar radiation causes significant retinal injury. There is no evidence in the provided literature contesting this established medical fact.
