Eye Tests

About the eye test

Eye tests are available at most opticians, however please be aware that not all opticians offer one-time eye tests. Please make sure that your eye test is comprehensive (which should include the use of an eye chart) and that you leave with all of the relevant information:

  • The sphere (S, SF or SPH) and/or cylinder value of each eye (C or CYL).
  • If there is a cylinder value, there must also be an axis value (A, As, AXI, AXS or AXIS).
  • The pupillary distance (PD) of each eye (divide value by two if only one value provided).
  • For varifocal glasses, the reading addition (ADD) for each eye.


Tips for your eye test

  • We advise that you contact the optician in advance to make an appointment.
  • Make sure that you have removed your contact lenses at least 30 minutes before your eye test (preferably several hours before).
  • If you're wearing hard lenses we strongly advise not to wear them on the day of your eye test.
  • Contact lens prescriptions differ from glasses prescriptions.
  • Your optician will also be able to adjust the fit of your new frames if needed.
  • We suggest that you have your eyes checked every 2 years.
