This complete guide from Dangui Opticians will walk every beginner through the non-negotiable rules of contact lens care, step-by-step. With over 92 years of expertise in eye care across Goa, we've helped thousands of contact lens wearers maintain healthy, comfortable vision.
🧼 The Golden Rules of Contact Lens Hygiene
These three rules form the foundation of safe contact lens wear. Never, under any circumstances, ignore them.
Rule #1: Always Wash Your Hands First
Before touching your lenses or your eyes, wash your hands thoroughly with antibacterial soap and water. Use a lint-free towel to dry them completely. Any residue or moisture can transfer germs directly to your lens, and then to your eye. Avoid moisturizing soaps that leave oily residue.
Rule #2: Only Use Fresh Solution
Never "top off" the solution in your case. This dilutes the disinfectant and allows bacteria to thrive. Dump out the old solution every time you remove your lenses and refill the case with fresh, sterile solution before storing them. Old solution is a breeding ground for infection.
Rule #3: Water is the Enemy
Do not allow your lenses to come into contact with water—tap, distilled, bottled, or even ocean/pool water. Water can harbor microorganisms (like Acanthamoeba) that cause severe, sight-threatening eye infections.
- Remove your lenses before showering, swimming, or using a hot tub
- Never rinse your lenses or lens case with tap water
- Never use saliva to wet your lenses—your mouth contains bacteria that don't belong in your eyes
Quick Tip: Make these three rules your mantra. Proper contact lens care prevents over 90% of lens-related eye infections. Your eyes are precious—protect them with consistent habits.
📋 Essential Contact Lens Care Supplies
Having the right supplies is the first step to proper lens care. Here's what you'll need:
- Multi-purpose contact lens solution: For cleaning, rinsing, disinfecting, and storing lenses (never use water or saliva)
- Fresh lens case: Replace every 3 months to prevent bacterial buildup
- Rewetting drops: Approved for contact lens use to combat dryness throughout the day
- Backup eyeglasses: Essential for days when you can't or shouldn't wear contacts
- Travel-size solutions: Factory-sealed bottles for on-the-go care
- Lint-free towels: For drying hands before handling lenses
- Phone reminders: Set alerts for lens replacement and case replacement dates
🧴 Step 1: Handling and Storing Your Lenses
How you remove, clean, and store your lenses directly impacts your eye health.
Insertion and Removal Best Practices
Start with the Same Eye: Always handle the same lens (e.g., the right one) first. This prevents accidentally swapping your left and right lenses, which is important if you have different prescriptions for each eye.
Check the Lens Orientation: Before putting the lens in your eye, ensure it's clean, not torn, and correctly oriented. A lens is correctly oriented if it looks like a smooth bowl with straight edges (the "U" shape). If it's inside-out, the edges will flare out slightly (the "V" shape).
- Wash and dry your hands thoroughly with lint-free towel
- Place the lens on your index finger and check it's not inside-out (U-shape, not V-shape)
- Hold your upper eyelid against your brow bone with your other hand
- Pull down your lower eyelid with the middle finger of the hand holding the lens
- Look up or straight ahead and gently place the lens on your eye
- Close your eye and gently massage your lid, or blink a few times to help the lens settle
- Repeat for the other eye, maintaining your same-eye-first routine
- Wash and dry your hands thoroughly
- Look up while pulling down your lower eyelid with your middle finger
- Use your index finger to gently slide the lens down to the white part of your eye
- Gently pinch the lens between your thumb and index finger
- Remove and immediately place in your palm with fresh solution for cleaning
- Never store lenses without cleaning them first
The "Rub and Rinse" Method
Even with "No-Rub" solutions, eye care professionals at Dangui Opticians strongly recommend a gentle rub for the most effective cleaning:
- Place the lens in the palm of your clean, dry hand
- Add a few drops of fresh multi-purpose solution
- Gently rub the lens with one finger in a back-and-forth motion for about 20 seconds on each side
- This mechanical cleaning removes debris, protein deposits, and lipids that solutions alone can't eliminate
- Rinse the lens thoroughly with a steady stream of fresh solution before placing it in the case
Pro Tip: The rubbing motion is critical—it physically removes 90% of debris. Don't skip this step even if your solution says "no-rub." Think of it like brushing your teeth; the mechanical action matters.
Caring for Your Lens Case
The lens case is a significant source of contamination if neglected. Follow these essential steps:
- Rinse Daily: Empty and rinse the case with fresh contact lens solution (never water) after placing your lenses in your eyes
- Air-Dry: Leave the case open and upside down on a clean, lint-free tissue to air-dry completely
- Replace Regularly: Replace your contact lens case every three months—no exceptions! Even with proper cleaning, biofilm and germs build up over time
- Mark Your Calendar: Set a phone reminder for case replacement dates
- Weekly Deep Clean: Once a week, gently rub the inside of the case with your clean finger and fresh solution, then rinse and air-dry
🧪 Step 2: Understanding Contact Lens Solutions
Choosing the right solution is crucial, but it can be confusing. Always follow the specific instructions from your Dangui Opticians optometrist and the solution manufacturer.
Multi-Purpose Solution (MPS)
- What it is: The most common type. It cleans, rinses, disinfects, and stores the lens in one bottle
- Best For: Most soft lens wearers. It offers the simplest routine
- Crucial Tip: Never mix solution brands. If you switch solutions, clean your case thoroughly before using the new brand. Different preservatives can interact and reduce effectiveness
Hydrogen Peroxide Solution
- What it is: A preservative-free system that uses hydrogen peroxide to deeply disinfect. It usually comes with a special case containing a neutralizing disc (catalyst)
- Best For: Users with sensitive eyes or those prone to protein buildup and allergies to preservatives
CRITICAL WARNING: You MUST allow hydrogen peroxide solution to neutralize completely (usually 6 hours minimum) before putting the lenses in your eyes. Putting un-neutralized peroxide in your eye will cause an extremely painful chemical burn requiring emergency treatment. Never rush this process!
Saline Solution
- What it is: A sterile salt-water solution that is only used for rinsing. It does NOT clean or disinfect
- Best For: Rinsing the lens after cleaning or before insertion (if needed)
- Crucial Tip: Never use saline solution for storage or primary cleaning—it has no disinfecting properties
Travel Tip: Never transfer solution into smaller travel bottles. The small bottles are not sterile and can become contaminated, rendering the solution unsafe. Always buy factory-sealed travel-sized solutions for trips.
⏰ Step 3: Following the Replacement Schedule
Contact lenses are not meant to last forever. They are made from porous materials that naturally accumulate deposits over time, even with perfect cleaning. Never wear a lens past its recommended schedule—trying to stretch the wear time is a direct risk to your eye health.
| Lens Type |
Replacement Schedule |
Why it Matters |
| Daily Disposables |
Discard after one use |
Most hygienic option. Eliminates the need for daily cleaning or solution costs. Perfect for beginners. |
| Two-Week Lenses |
Discard after 14 days from opening the foil pack |
Strict adherence prevents eye irritation and infection from old deposits. Count calendar days, not wear days. |
| Monthly Lenses |
Discard after 30 days from opening the foil pack |
Requires consistent, meticulous daily cleaning. Most economical for regular wearers. |
Important: The replacement schedule starts from the day you open the foil pack, not from the number of days worn. If you open monthly lenses on November 1st, discard them by December 1st—even if you only wore them 10 times. If you're unsure of your schedule, check the box or consult your Dangui Opticians optometrist.
🚫 What to Avoid When Wearing Contact Lenses
Certain situations require special attention when you're a contact lens wearer. Here's your quick-reference guide:
| Situation |
Action |
Why? |
| Using Eye Drops |
Only use rewetting drops specifically approved for use with contacts |
Most conventional eye drops can interact with the lens material and cause damage or irritation |
| Sleeping in Lenses |
Never sleep in lenses unless specifically prescribed for extended wear |
Sleeping in contacts drastically increases your risk of serious infection and corneal oxygen deprivation (hypoxia) by 6-8 times—even for short naps |
| Sharing Lenses |
Never share lenses—not even colored cosmetic contacts! |
Sharing lenses is an easy way to transfer bacteria, viruses, and eye infections. Each lens is fitted to specific eye measurements |
| Applying Makeup |
Insert your lenses BEFORE applying makeup |
If you insert them afterward, there's a higher chance of makeup residue, oils, or particles getting trapped under the lens |
| Removing Makeup |
Remove your lenses BEFORE removing makeup |
This prevents makeup remover, oils, or residue from getting on the lens and causing irritation |
⚠️ When to Remove Your Lenses Immediately
If you experience any of the following symptoms, remove your lenses immediately and put on your backup glasses. Do not reinsert the lenses and call your eye care professional at Dangui Opticians right away:
- Redness: Persistent redness that does not go away after removing the lens
- Pain: Any unusual, persistent pain or burning sensation
- Tearing: Excessive watering or unusual discharge from your eye
- Blurred Vision: Sudden or worsening blurriness that doesn't clear
- Light Sensitivity: Unusual sensitivity to light (photophobia)
- Foreign Body Sensation: Feeling like something is stuck in your eye that won't go away
Your eyes are precious. These symptoms could indicate serious conditions such as corneal ulcers, infections, or abrasions requiring immediate professional attention. Never ignore warning signs or try to "push through" discomfort.
💡 Common Issues and Quick Solutions
Dry or Uncomfortable Lenses
- Use preservative-free rewetting drops approved for contact lens wear
- Blink consciously and regularly, especially during screen time (digital eye strain reduces blink rate by 60%)
- Stay hydrated by drinking adequate water throughout the day
- Consider switching to daily disposables or high-moisture lenses
- Use a humidifier in dry, air-conditioned environments
- Read our digital eye strain prevention guide for more tips
Blurry Vision
- Check if the lens is inside-out (V-shape instead of U-shape)
- Check if the lens is dirty—clean and reinsert it
- Ensure you're using the correct lens for each eye (this is why the same-eye-first routine matters!)
- If blurriness persists, schedule an eye exam—your prescription may have changed
Lens Sticking to Your Eye
- Apply approved rewetting drops and wait a few minutes
- Gently massage your closed eyelid to help redistribute moisture
- Never force a dry lens to move—this can damage your cornea
- If the lens won't move after 10 minutes with drops, contact your optometrist
❓ Frequently Asked Questions
How often should I replace my contact lens solution?
Always use fresh solution every time you store your lenses. Never top off old solution, as this reduces disinfection effectiveness and creates a breeding ground for contamination. Think of it like reusing bath water—you wouldn't do that, right?
Can I rinse my contact lenses with water in an emergency?
Absolutely not. Water should never touch your contact lenses under any circumstances. If you don't have solution available, it's safer to discard disposable lenses or keep reusable lenses in your eyes until you can access proper solution. If you're traveling, always pack extra solution.
Is it okay to sleep in my contact lenses occasionally?
Only if they're specifically prescribed for extended wear by your optometrist. Sleeping in regular contact lenses—even for a 20-minute nap—dramatically increases your risk of serious, sight-threatening eye infections by 6-8 times. Your closed eyelid already reduces oxygen to your cornea; adding a lens makes it worse.
How long can I wear my contact lenses each day?
Most optometrists recommend 10-12 hours maximum daily wear for standard lenses. However, individual recommendations vary based on lens type, material, and your eye health. Always follow your Dangui Opticians optometrist's specific guidance. Give your eyes regular "glasses days" to breathe.
Can I use expired contact lens solution?
Never use expired solution. The disinfecting agents lose effectiveness over time, leaving you vulnerable to infections. Check expiration dates regularly and discard expired bottles immediately, even if they're unopened.
What if I accidentally put the wrong lens in the wrong eye?
Remove both lenses immediately, clean them properly with fresh solution, and reinsert them in the correct eyes. Your lenses are specifically prescribed for each eye's unique measurements and prescription. Wearing them switched can cause discomfort, blurred vision, and eye strain.
🎯 Building Healthy Contact Lens Habits
Success with contact lenses comes down to consistency and discipline. By committing to this simple but vital care routine, you ensure your contact lens experience is comfortable, clear, and safe. Here's how to make proper lens care second nature:
- Set a Routine: Establish consistent morning and evening lens care habits. Do it at the same time each day—like brushing your teeth
- Keep Supplies Stocked: Always have backup solution, fresh cases, and extra lenses on hand. Running out is not an excuse to cut corners
- Use Technology: Set phone alerts for lens replacement schedules, case replacements (every 3 months), and annual eye exams
- Never Cut Corners: Even when you're exhausted or in a hurry, follow proper care procedures. Infections don't care about your schedule
- Listen to Your Eyes: If something feels wrong, take it seriously. Remove your lenses and give your eyes a break
- Maintain Backup Glasses: Always have a current eyeglass prescription and a pair you actually like wearing
Annual Eye Exams Are Non-Negotiable: Regular comprehensive eye exams are essential for contact lens wearers. Your prescription, eye health, corneal shape, and lens fit should be evaluated annually at minimum. Your eyes change over time—your care should keep pace.
Contact lenses are a wonderful technology that provides clear vision and freedom from frames. With proper care and attention to hygiene, you can enjoy safe, comfortable lens wear for years to come. Your eyes are worth the effort.
