Monsoon brings with them high humidity which is the leading cause of many eye infections. It could trigger a bout of conjunctivitis, an unappealing stye and unwanted corneal ulcers. So what's the best way to ensure that common eye infections don't turn into something serious? If you experience any sort of redness, swelling or burning sensation in the eye, avoid self-medication and instead immediately consult an ophthalmologist.

"Diseases like conjunctivitis, corneal ulcers, eye styes are very common in the monsoon. People enjoy the monsoon season but they are not aware that even direct contact between the eyes and the rain water can cause many types of infections," said Kamal B. Kapur, an ophthalmologist associated with city-based Sharp Eye Centre.

"Corneal ulcers are dreaded, they may even cause blindness. It is a severe form of eye infection due to viral, bacterial or fungal infection.

It occurs as a red, painful eye, with mild to severe discharge and reduced vision. It should not be ignored," said Mahipal Sachdev, Chairman centre for sight (CFS) "This painful little bump is a limiting condition which ruptures on its own.

Avoid popping a stye. The only way to avoid it is by the usage of warm water, which reduces the inflammation and pain of the stye.

"Eye stye occurs in the form of a lump on the eyelid. Its symptoms are excruciating pain, pus discharge, redness over eyelids.

Its basic treatment is warm and cold compresses at home, eye drops and other medication. But if the size of the lump increases, the patient needs to visit an ophthalmologist
