Testing of Contact Lenses

Manufacturers of hydrogels and finished-product contact lenses muss test certain elastic characteristics. To simulate the repeated application and removal of lenses, the break resistance of the dry and moist material, as well as the structure of the material at deflection, must be tested.

To simulate daily use, the following tests under normal conditions (in a saline solution) must be performed:

  • Deflection
  • Tear
  • Indentation force
