Actor Kartik Aaryan experienced blurry vision and a "film" over his eyes after prolonged swimming sessions for his role in 'Chandu Champion'. Doctors attributed the symptoms to excessive chlorine exposure, which can cause chemical conjunctivitis, also known as swimmer's eye. Aaryan described the experience as an "eye-opener," highlighting how extended pool time can impact eye health and potentially weaken the cornea and conjunctiva.
