Prescription Submission Required
After placing your order, email your prescription to sales@fairdcanada.com and include your Shopify order number.
- Required for prescription lenses: current prescription and pupil distance (PD) measurement.
- If PD is not printed on the prescription, request it from your optometrist and include it in the email.
- For Plano / Non-Prescription lenses, email the order number and confirm “Plano / no prescription required.”
- Orders cannot be processed until the required optical information is received.
Lens Type Comparison
| Lens type | Best for | Prescription required |
|---|---|---|
| Single Vision | One corrected distance, such as general distance vision. | Yes, with PD. |
| 28 mm Bifocal | Distance correction with a lined reading segment. | Yes, with PD. |
| Digital Progressive / No-Line Bifocal | Distance, intermediate and near vision without a visible bifocal line. | Yes, with PD. |
| Plano / Non-Prescription | No correction; used for clear, grey or yellow specialty lens color only. | No prescription, but order confirmation is required. |
Lens Color Comparison
| Lens color | Use case | Notes |
|---|---|---|
| Clear | General use and maximum light transmission. | Best default choice for indoor or mixed conditions. |
| Grey Tinted / True Color Reception | Bright outdoor conditions and glare reduction. | Designed to reduce brightness while keeping natural color perception. |
| Yellow Tinted / SMOKESIGHT XT | Smoke, low light and contrast enhancement. | Helpful when contrast and target visibility matter more than neutral color. |
Formula we use for prescriptions: order first, then email the prescription and PD to sales@fairdcanada.com with the order number in the subject line. We match the optical file to the Shopify order before sending the custom request to MIRA.
