Contact lens solution is a specially formulated liquid used by contact lens wearers to clean, disinfect, moisturize and store their lenses. Since lenses come into direct contact with the eye, maintaining their hygiene is extremely important to prevent infection and extend their lifespan. Op. Dr. Diclehan emphasizes that choosing the right lens solution is essential for protecting the eye health of contact lens users.
The main purpose of contact lens solutions is to remove protein, lipid and microorganism residues that accumulate on the lens surface. They also help preserve lens flexibility, maintain moisture balance and ensure compatibility with the eye surface.
Although lens solutions may contain different formulations, they generally include ingredients that clean, disinfect and moisturize the lenses.
These remove dust, oil and makeup residue from the lens surface.
Op. Dr. Diclehan recommends choosing solutions that provide strong cleaning power without damaging delicate eye tissues.
These chemicals keep lenses sterile. Agents such as hydrogen peroxide, polyhexanide or biguanide are effective against microorganisms and play a key role in preventing infections, especially with long-term use.
These ingredients prevent the lens from drying out and help keep the eye surface comfortable.
According to Op. Dr. Diclehan, solutions with high moisturizing content are particularly suitable for users with dry eye problems.
Different types of solutions are available depending on the type of lens and the user’s needs. This choice directly affects both comfort and eye health.
These solutions clean, disinfect, rinse and store lenses — all in one product. They are commonly preferred for daily use due to their practicality.
Op. Dr. Diclehan notes that these are the most popular type of solution.
Designed for a deeper cleaning. However, they must be neutralized before the lens is placed in the eye. These are usually recommended for people with sensitive eyes.
Used for rinsing and temporarily storing lenses, but they do not disinfect.
Op. Dr. Diclehan emphasizes that they are not sufficient for cleaning on their own.
Formulated to dissolve protein buildup on lenses used over long periods. Typically used once a week.
Contact lens solution not only cleans lenses but also protects eye health. Choosing the wrong solution can lead to serious eye problems.
According to Op. Dr. Diclehan, inappropriate solution use may cause redness, burning, stinging and even corneal infections. Therefore, the solution must be selected according to lens type and the individual’s eye structure.
The right solution preserves the lens material and reduces the risk of deformation, allowing lenses to be used for longer.
Bacteria grow easily on improperly cleaned or stored lenses, leading to serious infections such as keratitis.
Op. Dr. Diclehan states that these risks can be almost completely prevented with proper solution use.
Correct use is essential for effectiveness. Small mistakes can negatively affect eye health.
• Wash your hands with soap and rinse well.
• Remove the lenses.
• Place each lens onto your palm.
• Apply a few drops of solution.
• Gently rub in circular motions for 15–20 seconds.
• Rinse the lenses with solution.
• Fill the lens case with fresh solution and place the lenses inside.
Op. Dr. Diclehan recommends replacing the lens case weekly and refreshing the solution every time lenses are cleaned.
• Do not rinse lenses with tap water.
• Do not top up old solution.
• Do not expose the lens case to direct sunlight.
• Do not use expired solutions.
Each eye structure and lens type is different, therefore the solution should be selected individually.
Solutions for soft lenses differ from those used for rigid gas permeable (RGP) lenses.
Op. Dr. Diclehan recommends always using a solution designed for the specific lens material.
Some users may react to preservatives. If itching, redness or burning occurs, the solution should be changed and a doctor consulted.
Only clinically tested and medically approved brands should be preferred.
Op. Dr. Diclehan advises avoiding unknown brands.
People who spend long hours at a computer or in dry environments benefit from highly moisturizing solutions, as these reduce dryness and increase comfort.
Failure to follow hygiene rules may cause serious complications.
Insufficiently cleaned lenses can lead to microbial keratitis — an inflammatory condition of the cornea that may cause permanent vision loss if untreated.
Op. Dr. Diclehan states that poor cleaning habits are a major cause of such infections.
Some solution ingredients may trigger allergic reactions. Symptoms include itching, redness and watering.
Improper solutions may erode lens material, reducing comfort and durability.
Dry eye patients must choose their solution carefully.
Op. Dr. Diclehan recommends hyaluronic acid–containing solutions for users with dry eye complaints, as these support moisture retention.
• Store at room temperature
• Keep away from direct sunlight
• Always keep the bottle sealed
• Use within 90 days after opening
Op. Dr. Diclehan stresses the importance of checking expiration dates.
Can water be used instead of lens solution?
No. Tap water is microbiologically unsafe and may cause serious infections.
How often should solution be changed?
Fresh solution must be used every time lenses are stored.
Is it harmful to mix different brands?
Yes — formulas differ and may damage the lens material.
Op. Dr. Diclehan warns against brand mixing.
Can lens solution be used as eye drops?
Absolutely not. It is only for cleaning and storing lenses.
All contact lens users should have regular eye examinations.
Op. Dr. Diclehan recommends at least one check-up per year and choosing a solution under medical guidance.
• Not replacing lens cases for months
• Touching the bottle tip to the lens case
• Rinsing lenses with water
• Storing solution in the fridge
• Using expired products
Op. Dr. Diclehan warns that even simple mistakes may cause long-term corneal problems.
Contact lens solution is one of the most essential tools for protecting the eye health of contact lens users. Choosing the right product, maintaining proper cleaning habits and following hygiene rules are crucial.
Op. Dr. Diclehan emphasizes that lens solution use is an inseparable part of safe contact lens wear. In cases of burning, stinging, blurred vision or redness, an ophthalmologist should be consulted without delay.
