How to read my prescription?+
To finalize the purchase of your mask, you must pick a lens strength for each eye. Lens strength is the first number (SPH) on your eyeglass prescription:
| RX | SPH | CYL | AXIS |
|---|---|---|---|
| Right eye (O.D.) | +4.50 | -0.75 | 120.00 |
| Left eye (O.S.) | +2.75 | -0.75 | 35.00 |
The - sign indicates myopia (nearsightedness), the + sign hyperopia (farsightedness). If your prescription is not available, round to the nearest increment (e.g. for a correction of +2.75, choose +3.00). If your prescription is x.50, round down to the lower value (e.g., for +4.50, choose +4.00). This operation causes no loss of visibility.
If you have any doubt, or if you have presbyopia, please contact us for personal advice.
➝ Some optometrists indicate corrections in hundreds, e.g. -450, -275 (i.e. -4.50, -2.75).
➝ Our prescription masks are not suitable for people with severe astigmatism (CYL > 2.00), anisometropia or other vision impairments requiring bifocals or more complex lenses.

Masque tres bien pour ma vision
I accidentally ordered the wrong mask, and the BESEAS team was incredibly kind and helpful in resolving the issue. They offered to replace it free of charge and even covered the shipping costs. Then the local delivery provider caused a major delay, and at one point it seemed the package might be lost. BESEAS again stepped in and offered to send a new one free of charge if needed. In the end, the package arrived, and the mask is amazing—exactly what I was looking for. Great quality, excellent corrective lenses, and truly outstanding customer service. If you need a mask with correction lenses, look no further. 10/10.
Bought a mask with prescription lenses but I made a mistake in reading my prescription, contacted Beseas who without any question replaced the mask with the correct lens prescription. Great communication and I would happily recommend them to anyone.
J’avais peur que ce soit une arnaque, au vu du prix (très bas) et du fait qu’il n’y avait pas beaucoup d’avis sur le site, mais j’en ai commandé un pour Noël et il est parfait !
Je recommande !
