Contact lenses are safe and convenient when used correctly. Most serious eye infections in lens wearers are linked to a handful of avoidable habits. Follow these ten rules to keep your eyes healthy.
The ten rules
- Wash and dry your hands before touching your lenses or eyes.
- Keep water away. Never rinse lenses or the case with tap water, and do not swim or shower in lenses. Water can carry organisms that cause severe infections.
- Use fresh solution every time. Never top up old solution in the case.
- Rub and rinse reusable lenses with solution as directed, even with “no rub” products.
- Clean and air-dry the case after each use, and replace it at least every three months.
- Stick to the replacement schedule. Daily lenses are for one day only. Monthly lenses should be thrown away after a month.
- Do not sleep in lenses unless your doctor has prescribed lenses for overnight wear.
- Never share lenses, including coloured or cosmetic lenses.
- Do not buy cosmetic lenses without a prescription. Poorly fitting lenses can scratch and infect the eye.
- Keep a pair of glasses so you can give your eyes a break, especially when they feel tired or dry.
When to take lenses out and see a doctor
Remove your lenses and contact an eye doctor promptly if you have redness, pain, light sensitivity, blurred vision or discharge. Bring the lenses and case with you. Do not put the lenses back in until you have been checked.
Regular check-ups
Have your eyes checked at least once a year, even if you feel fine. Your doctor will look for early signs of strain on the cornea and update your prescription.

Frequently asked questions
Can I wear contact lenses in the monsoon or in dusty traffic?
Yes, but dust and pollution can irritate the eyes. Daily disposable lenses and wraparound sunglasses can help. Remove lenses if your eyes become uncomfortable.
How long can I wear lenses each day?
It depends on the lens and your eyes. Many people wear soft lenses comfortably for 8 to 12 hours. Ask your doctor for your limit.
