Vitamin-Enriched Defence: Antioxidant Benefits in Daily Wear

The role of micro-encapsulated vitamin E in combating oxidative stress and soothing irritation with every blink.

Your eyes work harder than you think. Every day, they are exposed to environmental stressors: UV rays from the sun, blue light from screens, and oxidative stress triggered by pollution and natural ageing. Over time, these factors can contribute to irritation, dryness, and fatigue — making comfort harder to maintain for contact lens wearers.

That’s why Clearlii developed vitamin-enriched lenses, designed to go beyond hydration and oxygen by adding a new layer of protection. By integrating micro-encapsulated vitamin E into the lens material, Clearlii lenses actively defend your eyes against oxidative stress while soothing the ocular surface with every blink.

What is oxidative stress?

Oxidative stress occurs when there’s an imbalance between free radicals (unstable molecules) and antioxidants in the body. In the eye, oxidative stress can:

• Destabilise the tear film
  
  

• Contribute to inflammation and redness
  
  

• Accelerate the feeling of eye fatigue
  
  

• Increase susceptibility to environmental irritants
  
  

Since the eye is constantly exposed to light and oxygen, it is especially vulnerable to oxidative stress. Contact lens wearers, who already ask more of their tear film, may feel these effects more acutely.

Vitamin E: nature’s antioxidant

Vitamin E is one of the body’s most effective antioxidants. It works by neutralising free radicals before they can damage delicate ocular tissues. In dermatology and nutrition, vitamin E has long been valued for its protective, soothing, and healing properties.

Applied to eye care, vitamin E can:

• Stabilise cell membranes to reduce irritation.
  
  

• Support tear film integrity for smoother, more consistent hydration.
  
  

• Reduce oxidative load from UV and blue light exposure.
  
  

By embedding vitamin E directly into contact lenses, Clearlii makes these benefits part of your everyday vision routine.

The innovation: micro-encapsulation

How can vitamin E be delivered in a controlled and effective way through a contact lens? The answer is micro-encapsulation.

In Clearlii lenses, microscopic capsules of vitamin E are integrated into the silicone hydrogel material. With each blink, small amounts are released onto the eye’s surface, providing:

• Gradual, sustained delivery – steady protection throughout the day.
  
  

• Localised effect – targeting exactly where protection is needed: cornea and tear film.
  
  

• No added routine – benefits are built into the lens, requiring no extra steps for the wearer.
  
  

Benefits for daily wearers

Vitamin-enriched lenses provide both immediate and long-term advantages:

1. Reduced sensation of fatigue

Wearers report eyes feeling fresher and less strained after long days of work, study, or screen use.

2. Calmer, less irritated eyes

Antioxidant protection helps reduce redness and inflammation associated with oxidative stress.

3. Enhanced tear film stability

With vitamin E supporting lipid layers, the tear film resists evaporation, keeping eyes moist.

4. Everyday defence

Built-in protection means your eyes are more resilient to environmental stressors like sunlight and digital screens.

Clearlii Vitamin lenses

Clearlii offers two vitamin-enriched daily disposable lenses:

• Clearlii Vitamin – daily disposable lenses enriched with vitamin E and hyaluronic acid. Designed to reduce the sensation of fatigue and keep eyes hydrated all day.
  
  

• Clearlii Vitamin Toric – with the same antioxidant and hydrating technology, optimised for wearers with astigmatism. Advanced stabilisation ensures sharp, stable vision while maintaining comfort.
  
  

Both options combine vitamin enrichment with Clearlii’s core innovations: silicone hydrogel for oxygen, Soft-Comfort Edge for smooth wear, and UV/blue-light filters for everyday defence.

Professional perspective

Opticians increasingly see patients with digital eye strain and environmentally stressed eyes. By recommending vitamin-enriched lenses, they can:

• Address both comfort and long-term ocular health.
  
  

• Reduce complaints of fatigue and irritation.
  
  

• Offer a clear differentiation from standard lenses.
  
  

Clinical studies indicate that lenses with embedded antioxidants can lower oxidative stress markers in tear film samples, further supporting professional confidence.

Myths about vitamin-enriched lenses

“It’s just a marketing claim.”
Not true. Micro-encapsulated vitamin E delivery is a patented, clinically validated technology that has measurable effects on oxidative stress.

“They must compromise oxygen or hydration.”
Clearlii Vitamin lenses are built on silicone hydrogel and hyaluronic acid — ensuring oxygen permeability and hydration remain uncompromised.

“Supplements are enough.”
Nutritional supplements support systemic health, but only localised delivery directly to the ocular surface provides immediate, targeted antioxidant protection.

Who benefits most?

Vitamin-enriched lenses are particularly valuable for:

• Screen-heavy lifestyles – students, professionals, and gamers.
  
  

• Outdoor enthusiasts – increased UV and environmental exposure.
  
  

• New wearers – easier adaptation with calming and protective properties.
  
  

• Sensitive eyes – reduced irritation for those prone to redness or dryness.
