Peripheral near vision if distance vision is poor, high myopia or decentrated pupil.

Procedure

Determine dominant eye
Find maximum convex (+) correction for distance vision
Find the best acuity in distance vision to optimise Zoc diameter choice
Determine the patients needs for: distance / intermediate / near Multifocal design choice

Quality assurance

These materials are in conformity with the standard ISO 10993-1 defining the biocompatibility of materials.

SwissLens manufacturing process warrants this biocompatibility even after the manufacturing process, in particular without adding polish material. This standard is required by the quality assurance system of SwissLens

Lunelle ES70

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

The researchers has led in the ’80 to the development of Essilor’s ES70 contact lens material, the most stable high quality material for soft lenses.
Through intensive research, ES70 has been proven to be one of the safest and healthiest lens materials that has been developed over time. Lenses made from ES70 material can be adapted to all types of visual defects with optimum safety and for a wide range of uses

LUNELLE ensures good oxygenation of the cornea

Material permeability is an important parameter in the fitting of contact lenses. For soft lenses, this permeability depends on the water content of the material.
The ES70 material used for Lunelle lenses has a hydrophily of 70%. It has a permeability (Dk) four times higher than that of HEMA and twice as high as that of a material with 55% hydrophily.
The choice of a non-ionic material gives a good resistance to deposits on the lens and therefore an optimal supply of oxygen throughout the life of the lens.
The material ES70 is composed of non-ionic polymers. It delivers a limited amount of protein substances to the lens surface, which ensures better visual quality.

LUNELLE ENSURES GOOD VISION FOR A LONG TIME

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

The ES70 Material

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.
