Lunelle ES70

Lunelle ES70 Material, the optimal solution for eye health and safety since the '80s.

Through intensive trials and research, ES70 has been proven to be one of the safest soft lens materials available. ES70 is versatile too and can be effectively used for the correction of all types of visual defects.

OUTSTANDING OXYGEN PERMEABILITY​

Material oxygen permeability is an important parameter to consider when fitting any contact lens. For soft lenses, material permeability is related to its water content. The higher the water content the lower the DK value.
However, while the ES70 material used for Lunelle lenses has a hydrophily of 70%, it simultaneously achieves a permeability (Dk) four times higher than that of HEMA and twice as high as that of a material with 55% hydrophily.
ES70 is a non-ionic material. This means Lunelle lenses are resistant to deposits. Fewer lens deposits means better visual quality, improved comfort and the optimisation of oxygen supply throughout the life of the lens.

GREAT VISION THROUGHOUT THE DAY

Lunelle considers the metabolism of the cornea. The geometry of the Lunelle lens ensures good mobility, so that a film of tears between the lens and the eye is ensured. This pumping effect contributes to a higher oxygen supply, so that the metabolism remains practically unchanged.
At the same time, the high-water content remains stable and ensures an optimal metabolism.
The combination of the ES7O material and the geometry of the Lunelle lens offers a completely safe fit by respecting the corneal metabolism.
Lunelle ES70 allows contact lenses to be used all lifelong.
The material is fully compatible with the cornea with special properties in the water bond, so that a stable geometry is achieved and therefore a low sensitivity to changes in pH, temperature and tonicity.
Lunelle lenses have good mobility and remain comfortable throughout the wearing period.
 

LUNELLE LENSES - FOR A PRECISE FIT OF ALL VISUAL DEFECTS

All Lunelle lens designs enable good mobility. This allows an excellent flow of tears between the lens and the eye and ensures optimal ocular health. This ‘pumping’ effect also contributes to a higher oxygen supply. When this is combined with ES70s high water content the metabolism of the eye remains practically unaffected, so patients can enjoy great comfort and vision all day.

The ES70 Composition

The ES70 material used for Lunelle contact lenses is composed of PMMA, which makes it robust and transparent, and PVP, which ensures a stable water content. The production of ES70 material will continuous after the take over by SwissLens. The same laboratorie will produce the row material and blank as before and exclusively availalbe for the Lunelle Products from SwissLens. The material involves the use of the most advanced techniques to obtain the stable material. The development of Essilor's polymerisation technology has proven to provide a very consistent material quality.

PRODUCTION SwissLens uses a high-tech lathing technique to achieve optimum reproducibility. Lunelle contact lenses are systematically inspected at all stages to ensure that the parameters remain the same in the dehydrated state
QUALITY GUARANTEE
The material and the contact lenses are produced in accordance with the strict rules laid down by Quality Assurance. This is an independent quality assurance service at Essilor, which ensures consistent product quality.
