Your contact lenses
Contact lenses are the same product in every shop, so these prices are exact per box.
Most people need one box per eye. Buying a year at once is usually cheaper per lens.
Choose a lens to compare prices.
Measure your PD from a photo
PD is the distance between your pupils. Most online shops need it. Your photo stays on your device.
- Take a straight-on selfie holding a bank or ID card flat against your forehead. Look at the camera, not the screen.
- Tap the left edge of the card.
- Tap the right edge of the card.
- Tap the centre of one pupil.
- Tap the centre of the other pupil.
– mm
Adult PD is usually between 54 and 74 mm. Measure twice; if the results differ by more than 2 mm, try another photo.
How to read your prescription
Prescriptions look different from country to country, but they use the same terms.
| SPH | CYL | Axis | ADD | |
|---|---|---|---|---|
| OD (right) | -2.00 | -0.50 | 90 | +1.50 |
| OS (left) | -2.25 | – | – | +1.50 |
OD and OS
OD is your right eye, OS is your left. Some prescriptions write R and L instead.
SPH (sphere)
Your main lens strength. Minus means short-sighted (far things are blurry), plus means long-sighted.
CYL and Axis
Correct astigmatism. Axis is a number from 1 to 180 and only appears when there is a CYL value. Copy both exactly.
ADD
Extra strength for reading, usually for people over 40. If you have an ADD, you may want progressive lenses or separate reading glasses.
PD
The distance between your pupils in millimetres. If it is not on your prescription, measure it with the PD tool.
Lens thickness (index)
A higher index means a thinner, lighter lens. Stronger prescriptions benefit most: above ±4.00, thin lenses make a clear difference.
Is it still valid?
Prescriptions usually expire after one to two years. Many shops ask for a valid one, and an eye exam also checks your eye health.
