Tetra- Flexi TC- Flexi B – Flexi W
Correcting contact lens
Successful contact lens with very favourable effect on the flow of tear fluid
In addition to a spherical optical zone, the Tetra contact lens has two spherical radii which are gradually flattening out in the periphery.
Spherical, Multifocal Prestige, Bifocal, Toric
The gradual increase in space between the cornea and lens surface, has a very favourable effect on the flow of tear fluid behind the contact lens. This effect makes Tetra a valued and successful contact lens. The periphery of the lens is about 1.00 mm wide. The Tetra lens can be used well with a normal tearfilm composition and tear amount.
