Legislation on the sale of reading glasses in pharmacies
Moon optician has a monopoly on the sale of medical devices that correct an ametropy (fault of refraction) therefore myopia, hypermetropy and astigmatism only. Presbytery is not part of it because it is a defect of accommodation due to the aging of the lens.
In 2003, in a judicial case between 29 officials and the trade union of the opticians of France, the Court of Cassation concluded that the presbytery is not a « lack of refraction such as ametropy but lack of accommodation due to aging ». This means that pharmacies in France, as well as any point of sale, are legally authorized to sell reading glasses in order to correct the presbytery.

Glass glasses, reading glasses, what is it?
The magnifying glasses are frames with convex lenses that magnify the vision to facilitate the reading of small characters. Depending on your degree of presbytery, you have to opt for a more or less important dioptry power:
- 42 years: +0.75 diopter;
- 44 years: +1.00 diopter;
- 48 years: +1.50 diopter;
- 52 years: +2.00 diopters;
- 56 years: +2.25 diopters;
- > 60 years: +2.50 diopters.
Generally, it is recommended to take reading glasses with the lowest power and which allow to read a small text to 40 cm evening the approximate length between the eyes and a book.
There are also glasses with depth of field lenses more commonly called degressive glasses or mid-distance. These are eyeglasses that allow you to see closely and have a degressive power up the glass. This allows to increase the playback distance up to 80 cm see 1.5 m especially when using a computer that requires intermediate vision.
Are magnifying glasses purchased at the pharmacy safe?
When you become presbyterian, you get tired more easily during reading or office work. The magnifying glasses purchased in pharmacy can be a temporary solution but it is recommended that consult an opthtalmologist to establish a precise prescription for your visual correction.
Indeed, the necessary correction of the presbytery may be different on your right eye than on your left eye. It probably also requires correction of light ametropy (myopia, hypermetropia, astigmatism).
The magnifying glasses are made in large volume so with standardized centers not necessarily corresponding to your pupil gap. It should be noted that our face is rarely symmetrical and the pupillary half-gauge (distance between the nose stop and your eye) of the right eye is very often different from the pupillary half-gauge of the left eye.
To conclude, reading glasses purchased at the pharmacy or supermarket are useful extra glasses until you get an appointment but we recommend you consult your opthalmo. In addition to the medical consultation which can detect any physiological problems, it will prescribe a precise optical correction corresponding to your visual needs.
