Flashcards

Vacuum anti-scratch coating machine

This machine applies a special coating to lenses, making them resistant to scratches.

Auto refractometer

Used to determine the power of a lens (spherical, cylindrical, or combined), and helps find refractive errors with near-infrared light.

Pupillometer (for measuring PD)

A device used to measure the distance between the centers of your pupils. It's important for making sure your glasses are centered correctly.

Phoropter or Refractor

A set of lenses used by an eye doctor to determine a patient's eyeglass prescription. It uses a combination of lenses to find the best correction for vision.
