How long should I not wear lenses before the preliminary examination?

The following rules apply prior to the preliminary investigation:

  • Soft contact lenses 1 week out
  • Hard contact lenses for at least 4 weeks
  • Night lenses for at least 8 weeks

Glasses voucher
To bridge these weeks, you can temporarily wear soft lenses if you have hard contact lenses or night lenses. You may wear your glasses during the last strictly contact-free week. Do you no longer have glasses? Then you can get a glasses voucher for Charlie Temple from us with a value of 50 euros.

Why leave out contact lenses?
Contact lenses can leave an imprint on the cornea. During the preliminary examination, the structure of the eye is measured, the health of the eye is examined and your visual requirements are mapped out. It is very important to be able to measure the natural shape of your cornea exactly during the preliminary examination. Only in this way is it possible to determine the correct calculations for the treatment.
