Further improvement in wearing comfort

Improvements made to conventional RGP lenses for comfortable wear.

Thin peripheral design

Improved from the design of Menicon TINU, the peripheral part of Four Seasons is about 15% thinner in order to reduce the contact with the eyelids. (About 40% thinner than Menicon Z)

Reduced weight

Due to the thinner lens periphery, the weight has been reduced by about 10% which results in less strain on the eyes.

Surface treatment to maintain moisture

Plasma treated to improve wettability and to prevent dirt and clouding while sustaining moisture.

*Wearing comfort may vary between individuals.

Four Seasons 5

A large amount of oxygen is delivered to the eyes

High oxygen permeability

Smoother tear exchange

RGP contact lenses are similiar in size than soft contact lenses, which enables tear replacement and more oxygen delivery.
