INSTRUCTIONS FOR USE
For a correct use of the trial lens ESSILOR, it is necessary to use a
pair of trial frames.
The lenses must be placed onto the trial frames, which have been
already placed on the patient’s face.
The operator, changing the type and dioptric power of the lenses,
allows the patient to have an optimal sight when looking at a test
chart. The operator is then able to make an assessment of the
correct prescription.
