Contact Lens Care: Do’s & Don’ts (কন্টাক্ট লেন্স যত্ন)

Contact lenses give you clear vision without frames — great for sport, style, or a change from glasses. But they sit directly on your eye, so a little carelessness can lead to irritation or a serious infection. The good news: safe contact lens use (কন্টাক্ট লেন্স যত্ন) comes down to a few simple do’s and don’ts.

Why contact lens hygiene matters

Because a lens rests on the surface of your eye all day, germs on your hands or in old solution can get trapped against the cornea. Poor habits are a leading cause of painful eye infections and even corneal ulcers. A few good routines keep your eyes safe and comfortable.

The Do’s ✅

• Wash and dry your hands before touching your lenses.
• Clean and store lenses in fresh solution every time — never yesterday’s.
• Follow the replacement schedule (daily, fortnightly, monthly) exactly.
• Store lenses in a clean case and replace the case every few months.
• Keep up regular eye check-ups to make sure your lenses still fit well.

The Don’ts ❌

• Don’t sleep in your lenses unless they’re specifically approved for it.
• Never use tap water or saliva to clean or wet lenses.
• Don’t overwear — remove them if your eyes feel tired or dry.
• Don’t reuse or “top up” old solution.
• Don’t wear lenses when your eyes are red, sore, or watery.

Contacts, dry eyes & infections

Lenses can worsen dry eyes, and dirty lenses raise the risk of infections like conjunctivitis (চোখ ওঠা). If your eyes become red, painful, or sensitive to light while wearing lenses, take them out and see an eye doctor.

When to switch to glasses

Give your eyes a break with glasses whenever your eyes feel dry or irritated, during any eye infection, or on long, tiring days. Having a comfortable backup pair is essential for every lens wearer.

Frequently Asked Questions

Can I sleep with my contact lenses on?

No, unless your lenses are specifically designed for overnight wear. Sleeping in regular lenses starves the cornea of oxygen and sharply raises infection risk.

Can I use water to clean my contact lenses?

Never. Tap water contains microbes that can cause severe eye infections. Always use fresh, proper contact lens solution.

How often should I replace my contact lens case?

Every one to three months, and always keep it clean and air-dried. A dirty case is a common source of eye infections.

What should I do if my eyes hurt while wearing lenses?

Remove the lenses immediately and switch to glasses. If pain, redness, or blurred vision continues, see an eye doctor promptly.
