The oDocs 20D PMMA lens is designed to provide optimal optical performance at the fraction of the cost. The lens comes with anti-reflective coating. Suitable for use in any form of indirect ophthalmoscopy or fundus camera design.
PMMA Lens: Since 1949 Intraocular lenses have been made of PMMA, due to its lightness, clarity and stability. Even today, PMMA is the material of choice.

Acrylic cracks more easily than polycarbonate under stress. 3 PMMA has light transmittance of 92 percent and PC has a light transmittance of 88 percent in comparison to glass. 4. PMMA Lenses. All of our lenses are produced with 1:1 Anterior-to-Posterior Curvature Ratio.
Polymethylmethacrylate (PMMA) was the first material to be used successfully in intraocular lenses. British ophthalmologist Sir Harold Ridley observed that Royal

Additionally, soft lenses contain water, which increases the likelihood of bacteria building up on lenses and causing an infection.
High mechanical strength. The relative molecular content of PMMA extruded lenses is about 2 million. It is a long-chain polymer compound with soft molecular forming chains. Polymethyl methacrylate (PMMA) Available in diopters 0.0D-8.0D; 8.5D-30.0D available in 0.5D increments; UV-A absorbing; Computerized lathe-cut optics; Ethylene oxide dry gas sterilized
1 PMMA has 17 times the impact resistance of glass, PC has 250 times the impact resistance of glass.
