What is lacreon in contact lenses
Lacreon is a technology developed by Johnson & Johnson Vision Care that is used in some of their contact lenses, such as Acuvue Moist and Acuvue Define. Lacreon permanently embeds a wetting agent called polyvinylpyrrolidone (PVP) into the lens material, which helps to keep the lenses moist and comfortable throughout the day.
PVP is a substance that is also found in natural tears, so it mimics the eye’s natural lubrication. Lacreon technology is different from other wetting agents that are only applied to the surface of the lenses and can be blinked away easily.
This ensures that the moisture is locked in the lenses and does not diminish over time. Lacreon technology is especially beneficial for people who suffer from dry eyes or work in dry environments. Lacreon technology is available in hydrogel contact lenses, which are made of a soft and flexible material that allows oxygen to pass through to the eyes.
Like other wetting technologies such as Hydraclear or HydraLuxe, Lenses with LACREON Technology utilize Polyvinylpyrrolidone (PVP).
Benefits of PVP in Contact Lenses:
- Comfort: High water absorption helps keep the lens hydrated and moist, preventing discomfort.
- Biocompatibility: PVP is generally well-tolerated by the eye, making it suitable for extended wear.
- Durability: High molecular weight contributes to the mechanical strength and shape retention of lenses.
- Optical Clarity: Aids in maintaining good optical clarity of the lenses.
What is the difference between lacreon technology and hydraluxe technology?
The differences between Lacreon and Hydraluxe technologies:
| Feature | Lacreon Technology | Hydraluxe Technology |
|---|---|---|
| Material Type | Hydrogel | Silicone Hydrogel |
| Lens Material | Soft and flexible | Rigid and durable |
| Oxygen Permeability | Allows oxygen through to the eyes | Higher oxygen permeability compared to hydrogel |
| Wetting Agent | PVP permanently embedded | Enhanced PVP network throughout the lens |
| Purpose | Keeps lenses moist and comfortable throughout the day | Lubricates the lens for effortless blinking, reducing dryness and irritation |
How to find Contact lens with lacreon ?
Contact lenses comes with a mention of Lacreon in the packaging. You can check that.
Benefits of LACREON technology in contact lenses (CL) :
- Extended Moisture Retention:
- It employs Polyvinylpyrrolidone (PVP), a water-absorbing substance, to enhance moisture retention in the lenses.
- PVP’s high water absorption capacity helps keep the contact lenses consistently hydrated, reducing dryness during wear.
- Biocompatibility:
- PVP is biocompatible with eye tissue, ensuring that the material is generally well-tolerated by the eye.
- This biocompatibility makes these lenses suitable for prolonged contact lens wear without causing adverse reactions.
- Durability and Mechanical Strength:
- The high molecular weight of PVP contributes to the durability and mechanical strength of the contact lenses.
- This characteristic helps the lenses maintain their shape, resist deformation, and ensures long-lasting performance.
- Optical Clarity:
- PVP aids in maintaining good optical clarity of the lenses, providing clear vision for the wearer.
- Enhanced Wettability:
- The proprietary integration process of PVP into the lens material enhances the wettability of the lens surface.
- Improved wettability allows tears to spread evenly across the lens, minimizing the formation of dry spots and enhancing overall comfort.
- Reduced Dry Eye Symptoms:
- By promoting even tear distribution and reducing dry spots, this technology helps minimize the occurrence of dry eye symptoms.
- Wearers may experience increased comfort throughout the day.
