Dry, burning, irritated or gritty eyes have become increasingly common with prolonged screen use, air-conditioned environments, pollution and other factors that affect the tear film. Lubricating eye drops are commonly used to provide temporary relief from these symptoms, and Carboxymethylcellulose Eye Drops in India are among the widely available artificial-tear formulations for dry eyes.
Carboxymethylcellulose (CMC) acts as an ocular lubricant. It helps lubricate the surface of the eye and provides temporary relief from dryness, burning, irritation and discomfort associated with dry-eye symptoms.
Several brands offer Carboxymethylcellulose formulations in different concentrations and combinations. Nayan Vision’s ophthalmic portfolio includes Boxycarb 0.5%, Boxycarb 1% and Boxycarb Plus. This guide explains Carboxymethylcellulose eye drops, their uses and some of the products available in India.

4. Refresh Tears Eye Drops
Refresh Tears is a Carboxymethylcellulose Sodium-based artificial-tear formulation available in India.
It is used as an ocular lubricant to provide temporary relief from dry-eye symptoms such as burning and irritation.
As an artificial-tear formulation, its purpose is to supplement lubrication rather than treat bacterial infections, allergies or other unrelated causes of red and uncomfortable eyes.
5. Refresh Liquigel Eye Drops
Refresh Liquigel is another Carboxymethylcellulose-based lubricant formulation.
The formulation is intended for dry-eye lubrication and provides an option for people requiring artificial tears for ocular-surface dryness.
The suitability of different lubricant formulations can vary depending on the severity and pattern of dry-eye symptoms.
6. Optive Eye Drops
Optive belongs to the artificial-tear category and uses Carboxymethylcellulose within its lubricating formulation.
Lubricating eye drops can help reduce discomfort associated with an unstable or insufficient tear film.
The product is intended for dry-eye symptom management rather than infectious or allergic eye conditions.
7. Celluvisc Eye Drops
Celluvisc is another Carboxymethylcellulose Sodium-based ocular lubricant.
CMC formulations can differ in concentration and viscosity. More viscous products may remain on the ocular surface differently from thinner artificial tears.
This is why the appropriate formulation should be selected according to individual dry-eye requirements and professional advice.
8. Lubistar-CMC Eye Drops
Lubistar-CMC is another CMC-based artificial-tear formulation available in the Indian pharmaceutical market.
Like other Carboxymethylcellulose products, its principal purpose is ocular lubrication and relief from symptoms associated with eye dryness.
9. Tearmax-CMC Eye Drops

CMC-based artificial tears help supplement the natural tear film and reduce friction and discomfort associated with insufficient ocular lubrication.
10. Aquim-CMC Eye Drops
Aquim-CMC is another Carboxymethylcellulose-based eye lubricant available in India.
As with other artificial tears, the exact formulation, concentration, preservatives and instructions should be checked before use.
What Is Carboxymethylcellulose?
Carboxymethylcellulose, commonly abbreviated as CMC, is an ingredient widely used in artificial tears and ophthalmic lubricant formulations.
When used in eye drops, CMC helps retain moisture on the ocular surface and supplements natural lubrication.
This can provide temporary relief from common dry-eye symptoms such as:
- Burning
- Stinging
- Irritation
- Grittiness
- Dryness
- Eye discomfort
- Tired or uncomfortable eyes
Carboxymethylcellulose is therefore primarily a lubricant, not an antibiotic, antihistamine or steroid.
What Are Carboxymethylcellulose Eye Drops Used For?
Carboxymethylcellulose Eye Drops in India are primarily used as artificial tears for dry and irritated eyes.
They may be useful when dryness is associated with factors such as:
- Prolonged computer or smartphone use
- Air conditioning
- Wind
- Dry environments
- Pollution
- Reduced blinking
- Reading for extended periods
- General ocular-surface dryness
CMC eye drops provide lubrication but do not necessarily address the underlying cause of persistent dry-eye disease.
If symptoms are frequent or severe, an eye examination can help identify why the eyes are becoming dry.
How Do Carboxymethylcellulose Eye Drops Work?
The surface of a healthy eye is continuously covered by a tear film.
When the quantity or quality of tears is insufficient, the ocular surface can become dry and irritated.
Carboxymethylcellulose acts as a lubricant and helps supplement the tear film. By retaining moisture and providing lubrication over the ocular surface, it can reduce friction and temporarily relieve dry-eye discomfort.
This is why CMC formulations are often described as artificial tears.
Carboxymethylcellulose 0.5% vs 1% Eye Drops
One of the common questions when comparing Carboxymethylcellulose Eye Drops in India is the difference between 0.5% and 1% formulations.
Carboxymethylcellulose 0.5%
A 0.5% formulation provides ocular lubrication in a relatively standard artificial-tear format.
Nayan Vision offers this concentration as Boxycarb 0.5%.
Carboxymethylcellulose 1%
A 1% CMC formulation contains a higher concentration of Carboxymethylcellulose and may have different viscosity and ocular-surface retention characteristics.
Nayan Vision offers this concentration as Boxycarb 1%.
A higher percentage should not automatically be interpreted as “better.” The suitable concentration depends on the person’s dry-eye symptoms, comfort and professional recommendation.
Carboxymethylcellulose Eye Drops for Dry Eyes
Dry-eye disease occurs when the eyes do not produce enough tears or when the tear film does not function adequately.
Common symptoms include:
- Dryness
- Burning
- Stinging
- Gritty sensation
- Eye fatigue
- Irritation
- Intermittent blurry vision
- Watery eyes
Although watery eyes may sound contradictory, ocular-surface irritation can sometimes trigger reflex tearing.
CMC artificial tears can supplement ocular lubrication and provide temporary symptom relief.
Carboxymethylcellulose Eye Drops for Computer Users
People working for long periods on laptops, desktop computers or smartphones may experience dry-eye symptoms.
One contributing factor is reduced or incomplete blinking during concentrated screen use.
Less effective blinking can increase tear evaporation and lead to symptoms such as dryness, burning, irritation and tired eyes.
Lubricating formulations such as Boxycarb 0.5% may provide temporary relief when symptoms are related to ocular-surface dryness.
However, artificial tears should be combined with sensible screen habits, including regular breaks and conscious blinking.
Can CMC Eye Drops Help Burning Eyes?
They may help when the burning sensation is caused by dryness or ocular-surface irritation.
Carboxymethylcellulose lubricates the ocular surface and can temporarily relieve burning and discomfort associated with dry eyes.
However, burning can also result from allergies, infection, chemical exposure, contact-lens problems or other conditions.
Persistent or severe burning should therefore not automatically be treated as dry eye.
Carboxymethylcellulose vs Sodium Hyaluronate Eye Drops
Both Carboxymethylcellulose and Sodium Hyaluronate are used in lubricant eye drops, but they are different ingredients.
Carboxymethylcellulose: An ocular lubricant widely used in artificial-tear formulations.
Sodium Hyaluronate: Another lubricating and moisture-retaining ingredient used in dry-eye formulations.
Nayan Vision offers products in both categories: Boxycarb contains Carboxymethylcellulose, while Hylowar contains Sodium Hyaluronate.
The choice between lubricant formulations depends on individual dry-eye requirements rather than one ingredient universally being better than the other.
Carboxymethylcellulose vs Polyethylene Glycol Eye Drops
Polyethylene Glycol is another ingredient commonly found in artificial tears.
Nayan Vision’s PGP Eye Drops, for example, contain Polyethylene Glycol 0.4% with Propylene Glycol 0.3%.
CMC and PEG-based products both aim to improve ocular lubrication, but their formulations differ.
Someone who experiences persistent dry-eye symptoms despite using one type of artificial tear may need an eye-care professional to assess the tear film and recommend an appropriate formulation.
Are Carboxymethylcellulose Eye Drops Safe for Daily Use?
Artificial tears containing Carboxymethylcellulose are commonly used for dry-eye symptom relief.
However, frequency of use depends on the formulation and individual needs.
People who need artificial tears very frequently should discuss their symptoms with an eye-care professional. Preservative content and the underlying cause of persistent dryness may become relevant when drops are used repeatedly.
Always follow the directions provided with the specific product.
Side Effects of Carboxymethylcellulose Eye Drops
CMC eye drops are generally used as lubricants, but some people may experience temporary effects after application.
These can include:
- Temporary blurred vision
- Mild burning or stinging
- Temporary irritation
- Sticky sensation
- Eye discomfort
If symptoms are severe, persistent or worsen after using the product, discontinue inappropriate self-treatment and seek professional advice.
How to Use Carboxymethylcellulose Eye Drops
Wash your hands before applying eye drops.
Tilt your head backwards and gently pull down the lower eyelid to create a small pocket.
Hold the bottle above the eye without allowing the dropper tip to touch the eye, eyelid or eyelashes.
Instill the recommended number of drops and gently close the eye.
Avoid touching the dropper tip against any surface because this can contaminate the bottle.
Follow the instructions provided for the particular formulation or those given by your eye-care professional.
When Should You See an Eye Doctor for Dry Eyes?
Occasional mild dryness can be common, particularly after prolonged screen use or exposure to dry environments.
However, consult an eye-care professional if you experience:
- Persistent dry-eye symptoms
- Significant eye pain
- Severe redness
- Light sensitivity
- Persistent blurry vision
- Eye discharge
- Symptoms that continue despite lubricant use
- A sudden change in vision
Persistent dry eye can have multiple causes, and repeatedly using artificial tears without identifying the underlying problem may not be sufficient.
