It is the ophthalmologist who tests, adapts and prescribes the lenses after having them tried on by the patient.
Two situations may arise:
– Either the person already has lenses of which they know the references (exact and detailed) in which case the prescription will be simplified and a single consultation will be enough to check, adapt, and possibly improve the lenses already worn.
– Either the person does not know their lens references or has never worn them: it is therefore necessary to start the tests again from scratch and do tests at the center:
- 1st short test approximately 1 hour
- 2nd long test: 4 hours to check the good tolerance of the lens: the lenses are provided by the Center.
At the end of these tests, if they are satisfactory, the ophthalmologist prescribes the definitive lenses that the patient will order from his optician who will specify the wearing times, maintenance and handling.
On the first day, you should wear the lenses for 4 hours and then increase by one hour per day to get your eye used to it, without ever exceeding 10/12 hours per day of continuous wear.
In certain cases, lenses can be reimbursed by social security:
- Irregular astigmatism
- Keratocoma
- Myopia greater than or equal to 8 diopters *
- Aphakia
- Anisometry greater than 3 diopters not correctable by glasses
- Strabismus accommodative
In the cases mentioned above, health insurance reimburses 65%, based on an annual flat rate from date to date, per eye, set at 39.48 euros, or 25.70 euros (whether the lenses are reusable or not, daily or weekly).
Most mutual insurance companies offer a variable lens package depending on the case (consult your mutual insurance company).
* What is the difference between visual acuity in tenths and correction in diopters?
Visual acuity is measured without correction. With correction, it is expressed in tenths or other international units.
Visual correction is expressed in diopters, it is the number of diopters that you need to add to best correct your vision and therefore give you your best acuity: 10 tenths most often, sometimes less rarely more.
