Very often people with a red eye will use over the counter medication when the eye turns red. This is to avoid a “cumbersome” visit to the Eye Doctor. However very often the chemist will offer a formulation containing an astringent (like Visine or Andre I kul) to cause rapid “whitening” of the eye. This is more harmful as it could cause rebound redness which could be worse than the initial presentation!
More alarming is the OTC drops could contain steroids. Steroid eyedrops would mask any underlying infection. Hence the eye would whiten rapidly while the underlying infection continues unabated. This could Lead to a deeper infection which spreads from the conjunctiva (white part of the eye) to the cornea (clear window in front of the eye). This is a much more serious condition with potentially severe visual problems as well.
Hence at any signs of redness or infection in the eyes do consult us. We are happy to help!
