Make it a point to take out and rinse your contact lens as poor lens hygiene can lead to a range of nasty eye ailments, including microbial keratitis, an infection of the cornea, the clear frontal part of the eye where lenses sit. Left untreated, it can lead to permanent visual damage — and, in extreme cases, blindness.

The eye has natural protection against the foreign bodies — through a fluid covering the eye that contains protective enzymes and by blinking, which prevents anything sticking to the eye’s surface. Yet minute air and waterborne microbes sometimes break through these defences, penetrating the protective layer of cells on the cornea. The bacteria pseudomonas is the most common keratitis-causing microbe, breeds in dirty contact lens case, say the experts.
