Blurry vision is usually associated with refractive errors, screen strain, or ageing. However, eye specialists say that in a few cases, hazy or fluctuating eyesight may signal something deeper, a deficiency of a vitamin that affects eye health. “Essential vitamins have a major say in keeping up the eye’s structure and function, especially the retina, cornea, and optic nerve. When the levels are below the normal ranges, various symptoms of visual disturbances may start showing in the eye; these may appear either gradually or suddenly,” said Dr Madhavi Jeste, Consultant – Ophthalmology, S.L. Raheja Hospital.
