World Sight Day 2024: Contaminated Water Can Make You Go Blind, Say Experts; Know How

Never take your eyes for granted, as they are among the most important, yet most sensitive organs which need extra care. According to experts, a lot of ocular diseases and conditions can be attributed to dirty and contaminated water which is loaded with particles that cause eye irritation – including redness, itching, and stinging.

Experts say it happens due to the presence of foreign substances that come into contact with delicate eye tissues – causing severe infections that affect vision. “What many people don't realize is that the water we drink, bathe in, and use for hygiene plays a crucial role in protecting our vision. Contaminated water carries harmful bacteria, parasites, and pollutants that can lead to serious eye infections, irritations, and long-term vision damage,” Dr. Noshir Shroff,Medical Director, of Shroff Eye Centre, told Times Now.

According to Dr. Shroff, in areas with limited access to clean water – the risks multiply in huge numbers - making preventable eye conditions far too common. “Clean water isn't just about staying hydrated, it is a frontline defense for your eyes and overall health. The path to preserving sight begins with the very water we rely on daily,” he added.

Dr. Shroff says dirty water leads to many serious eye problems in a number of ways, including:

Also known as Pink Eye, the condition happens due to exposure to bacteria or viruses in unclean water. “This leads to redness, itching, and a discharge from the eyes, making them irritated and swollen,” he said.

Acanthamoeba keratitis is a rare eye infection caused by Acanthamoeba amoeba – usually found in untreated water. It infects your eyes, especially if you wear contact lenses and rinse them with tap water. If left untreated, this infection can cause corneal damage and permanent vision loss.

Hard water – which is packed with minerals, can worsen dry eyes by destabilizing the tear film, leading to discomfort, irritation, and a gritty sensation.

High amounts of chlorine in swimming pools or chemicals in polluted water can trigger allergic reactions, causing red, swollen, watery, and itchy eyes.

Open sores on the cornea are caused by bacteria, fungi, and other microorganisms in dirty water. Symptoms include pain, redness, discharge, and sensitivity to light.

According to Dr. Shroff, you must ensure access to clean water and following safe practices can help protect eye health:

Make sure to use filtered or boiled water for washing the face or eyes. Tap water may contain harmful microorganisms that could lead to infections.

Always use lens wipes that are carefully formulated to clean lenses effectively without scratching or leaving residue, protecting both your lenses and your eyes from irritation caused by dust or bacteria. “Use of good quality lens wipes not only maintains the clarity of your lenses but also ensures a hygienic, easy-to-use cleaning method that promotes long-term eye health,” said Dr. Shroff.

When swimming, make sure to wear goggles to protect your eyes from the irritants in pool water, such as chlorine.

Be cautious when it comes to using tap water for your eyes. Tap water may contain impurities like chlorine, bacteria, or heavy metals, which can irritate the delicate tissues of the eye. In some areas, water quality isn't always ideal, and exposure to these contaminants could result in infections or allergic reactions, potentially causing long-term eye health issues. As a doctor, I recommend washing your face with your eyes closed if you use tap water. This simple precaution can help protect your eyes in the long run.
