Conditions for the use and return of evaluation lenses

  • The lenses must be returned within the agreed time and in the same condition in which they were sent, i.e. with the surfaces free from scratches, abrasions or partial breakages.
  • As a result of the continuing Covid-19 emergency, the following is recommended: the lenses, after use with the patient, must be subjected to adequate disinfection and subsequently neutralized with the peroxide method.
  • Do not leave removed evaluation lenses soaked in fluorescein.
  • Store the evaluation lenses strictly dry in the primary container. Do not add preservative or saline solution.

In the absence of these requirements, the lenses will be returned and credited at the evaluation price relating to the type of lens according to the current price list.
