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 down to the nearest increment (e.g. for a correction of -3.75, choose -3.50). This operation causes no loss of visibility.
➝ 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.
➝ For any other questions, please contact us.
