Bayer Test Kit

The TABER Bayer Abrasion Test Kit is used with the Oscillating Sand Abrasion Tester to reproduce normal abrasion on the front of ophthalmic lenses. This test is applicable to all plana lenses and compares the sample with a control lens.

The Bayer test compares the abrasion generated on a test lens with an ISO reference lens (uncoated CR-39 lens). Both lenses are mounted on a special Bayer Test lens holder that allows the curvature of the lenses to protrude above the bottom of the tray. A standardized abrasive media called Alundum ZF-12 is in the tray. The tray alternately moves back and forth (back and forth) a distance of 4 inches, at 150 cycles per minute for 4 minutes. After the test, two lenses are removed from the tray and the amount of abrasion is measured and compared.
