Contact Lens Care Routine: Daily Steps, Case and Wear Hours
Water is the one thing a contact lens must never touch. Tap water, bottled water, shower water and spit can all carry germs that cause serious eye infections. A safe contact lens care routine is simple: clean dry hands, fresh solution every time, rub and rinse, a case that air-dries, and no sleeping in lenses unless your eye doctor prescribed that type.
Quick facts
- Daily time: about 3 minutes, morning and night
- Solution: fresh every time, never topped up
- Case: rinse with solution, air-dry upside down, replace every 1 to 3 months
- Wear hours: whatever your optometrist set, commonly 8 to 12 a day
- Red eye, pain, light sensitivity or blur: lenses out, eye doctor the same day

Why the routine matters so much
A lens sits on the cornea, the clear window at the front of your eye, and cuts down how much oxygen reaches it. Any germ trapped under the lens gets a warm, damp, low-oxygen place to grow. Most lens infections come from a handful of habits: topping up old solution, rinsing with water, sleeping in lenses and using an old case. Fix those four and you’ve removed most of the risk.
The water rule has a particular reason behind it. Tap and tank water can carry a tiny organism called Acanthamoeba. It rarely troubles anyone, but on a contact lens it can cause a painful corneal infection that’s hard to clear and can damage sight.
Contact lens care routine, step by step
Taking lenses out at night
- Wash hands with soap and water for 20 seconds, then dry them fully on a clean, lint-free towel. Wet hands put water on the lens.
- Remove one lens and put it in your palm.
- Add a few drops of fresh multipurpose solution and rub the lens gently with a fingertip for about 5 to 10 seconds each side (check your solution’s label, some ask for 20 seconds).
- Rinse it with more fresh solution for about 5 seconds.
- Place it in the correct side of the case (R and L are marked) and fill with fresh solution until the lens is covered.
- Repeat for the other eye, always starting with the same eye so you never mix them up.
- Close the case and leave it for at least the soak time on the bottle, usually 4 to 6 hours or overnight.
Putting lenses in (contact lens lagane ka tarika)
- Wash and dry hands. Do your hair spray and moisturiser first, so neither ends up on your fingers.
- Take the lens out, check it’s clean and not torn, and check it’s the right way out: it should look like a bowl, not a saucer with a flared rim.
- Look up, pull the lower lid down with your middle finger, and place the lens on the white of the eye or directly on the coloured part.
- Look down slowly, release the lid and blink a few times.
- Empty the case, rinse it with fresh solution (not water), wipe it with a clean tissue and leave it upside down, open, to air-dry.
The case: the part everyone forgets
An old case is often dirtier than the lenses. Germs form a slimy film inside that solution can’t fully reach. Rinse it with solution every morning, air-dry it face down on a clean tissue, and replace it at least every 3 months, or monthly if your optometrist suggests. Most solution bottles come with a new case, so swap it each time you open a new bottle.
Hydrogen peroxide systems are different. They come with their own special case that neutralises the peroxide over several hours. Use only that case, never put peroxide solution straight into your eye, and don’t shorten the waiting time on the box.
Daily lenses vs monthlies: how long contact lenses last
| Type | How long a pair lasts | Case needed |
|---|---|---|
| Daily disposable | One day of wear, then in the bin | No |
| Two-weekly | 14 days from opening | Yes |
| Monthly | 30 days from opening | Yes |
| Yearly or rigid (RGP) | As your optometrist sets | Yes |
Count from the day you open the blister, not the number of days you wore them. A monthly worn on only ten days still expires at 30. Put used lenses in the dustbin, never the toilet or sink. Dailies are the easiest option for people who wear lenses only for weddings, sport or the odd office day.
Contact lens hours per day, and the wearing schedule
Your optometrist sets your maximum wear time. Many daily-wear users are told 8 to 12 hours, and new wearers usually build up slowly.
- Day 1: about 4 hours.
- Each following day: add about 2 hours if your eyes feel fine.
- Stop at the limit your optometrist gave you, even if your eyes feel comfortable.
- Give your eyes a lens-free day or evening in glasses whenever you can.
No napping or sleeping in daily-wear lenses, not even for 20 minutes on a sofa. Only lenses prescribed for extended wear are meant for sleep, and even those carry a higher infection risk. No swimming or showering in lenses either. If you must swim, wear tight goggles and bin dailies straight afterwards.
Contact lens safety tips: makeup, screens and coloured lenses
Makeup, AC and screens
Lenses go in before makeup and come out before you take makeup off. Keep eyeliner outside the lash line, choose mascara that isn’t fibre-lengthening, and replace eye makeup every 3 months. Long hours at a screen and in AC make lenses feel dry because you blink less. Use only rewetting drops labelled for contact lenses, and follow the 20-20-20 break from our eye care tips for computer users.
Coloured lenses from shops and salons
Coloured and cosmetic lenses are medical devices, even with zero power. The ones sold from market stalls, beauty shops or social media are often one-size-fits-all, which means a poor fit that rubs the cornea. Sharing them after a wedding passes infections from eye to eye. If you want coloured lenses, get them fitted by an optometrist and follow the same care routine as any other lens. Never share lenses with anyone.
If you have eye pain, redness that doesn’t settle within an hour of removing the lens, sensitivity to light, blurred vision, a watery or sticky discharge, or a feeling of something stuck in the eye, take the lenses out and see an eye doctor the same day. Don’t put them back in. Bring the lenses and case with you, because they help find the germ. Don’t use steroid eye drops or leftover drops from someone else without a doctor’s advice, and don’t patch the eye. A white spot on the coloured part of the eye is an emergency. Children and teens can wear lenses once they can handle the care routine, but an adult should check it’s being done. Pregnancy can change lens comfort, so mention it at your next check.

Contact lens questions people ask
How many hours a day can I wear contact lenses?
As many as your optometrist allows, commonly 8 to 12 hours for daily-wear lenses. New wearers start at about 4 hours and build up by roughly 2 hours a day.
Can I sleep with contact lenses in?
No, unless your eye doctor prescribed extended-wear lenses for that. Sleeping in ordinary lenses sharply raises the risk of a serious infection, even for a short nap.
Can I clean contact lenses with water?
Never. Tap, bottled and boiled-then-cooled water can all carry germs that cause severe eye infections. Use only fresh contact lens solution.
How often should I change my contact lens case?
At least every 3 months, and ideally with every new bottle of solution. Replace it sooner if it’s cracked or looks cloudy.
Can I reuse contact lens solution?
No. Empty the case every morning and fill it with fresh solution every night. Topping up old solution leaves germs in it.
How long do monthly contact lenses last?
Thirty days from the day you open the blister, however many of those days you wore them.
Can I shower or swim with contact lenses?
Better not. Water can carry Acanthamoeba. If you must swim, wear tight goggles and throw daily lenses away afterwards.
What should I do if my eye is red with contact lenses?
Take the lenses out. If pain, redness, blur or light sensitivity don’t settle within an hour, see an eye doctor the same day and take the lenses and case with you.
Are coloured lenses from shops safe?
Not without a proper fitting. Unfitted cosmetic lenses can scratch the cornea and cause infections, so get even zero-power lenses from an optometrist.
Can I use normal eye drops with contact lenses?
Only drops labelled safe for contact lenses. Other drops may contain preservatives that bind to the lens. Medicated drops are for your doctor to advise.
Do I put makeup on before or after contact lenses?
Lenses first, then makeup. At night, take the lenses out before removing makeup.
At what age can children wear contact lenses?
There’s no fixed age. Many children manage from about 8 to 12 if they can wash hands and handle the lens well, with a parent overseeing the care.
How often should I get a contact lens check-up?
Usually once a year, or as your optometrist advises, even if your vision seems fine. The check looks at the health of the cornea as well as your power.
Can I wear my lenses if one feels scratchy?
Take it out, rinse it with fresh solution and look for a tear or dirt. If it’s damaged, throw it away. If the scratchy feeling stays with the lens out, get your eye checked.
