Product details for nearsightedness and farsightedness Product details for astigmatism

Considering eye healthFourth-generation silicone hydrogel contact lenses

Superior Surface Technology®

Rohto 2week FreshView®S is a 2-week disposable silicone hydrogel contact lens that uses fourth-generation coating technology.

The silicone hydrogel material, developed using our unique polymer synthesis technology, forms multiple layers of hydrophilic material on the lens surface.
Therefore, a film of water covers the surface of the lens, providing lasting moisture. *
With its high hydrophilicity and smooth, comfortable feel, you can enjoy a comfortable experience. *

* Wearing comfort varies from person to person.

Lenses designed with eye health in mind

Smooth lens surface

The hydrophilic layer reduces friction.
The lower the coefficient of friction, the more comfortable the fit. *1

Durability of water wettability

The smaller the contact angle, the better the wetting and the better the absorption of moisture.
It maintains its water-repellent properties even after 14 scrubs.

Stain resistance *4

The hydrophilic layer formed on the lens surface prevents dirt from adhering, maintaining a clear field of vision.

Oxygen permeability

Sufficient oxygen is necessary to maintain normal corneal function. Silicone hydrogel lenses offer exceptional oxygen permeability.

UV protection to shield you from ultraviolet rays *8

Numerous studies have shown that excessive exposure to ultraviolet (UV) radiation can have adverse effects on human health.
It blocks 98% of UV-B rays, which are particularly harmful to the eyes. *9

handling

The Silk Edge Design® provides a smooth and comfortable feel.
With a gentle design that conforms to the cornea, these lenses are gentle on the eyes.

The lenses are also easy to spot thanks to their tinted blue color.
These lenses maintain their shape well on your finger.

For astigmatism

Optimized Prism Ballast Design®

Unique design ensures lens stability even when blinking.

By minimizing the step created by the prism ballast design, the lens remains stable on the cornea even when blinking.
The evenly distributed, moderate thickness of the lens suppresses rotation, providing a clear and stable field of view.
Seamless, smooth design

While maintaining clear and stable vision and axis stability, we have also pursued improved wearing comfort.*9
