Colour-coded flipper lenses for the diagnosis and treatment of accommodative defects.
These plastic, colour-coded flipper lenses are available in a number of sizes and used for the diagnosis and treatment of accommodative defects. They comprise binocular spherical plus/minus lenses that can quickly be flipped from plus to minus during testing.
±0.50 DS, ±1.00 DS, ±1.50 DS, ±2.00 DS, +2.00/-4.00 DS, ±3.00 DS
The +/-2.00 DS is used to measure accommodative flexibility during a timed reading check. The other lenses are used to treat the condition by practising with a small sphere and increasing the lens strength used.
+/- 3.00 DS flippers are useful in orthoptic practise for diagnostic tests and measurements.
You can choose the required sizes in the drop down menu above. Please note that other sizes may be available upon request.
