Lens guide
Choose lenses with confidence. WOOglasses supports single-vision, astigmatism, progressive and prism prescriptions, subject to the chosen frame, prescription and required fitting measurements. Use the options shown on the product page, or contact us before paying for a combination that is not listed.
Understanding your prescription
Use a current spectacle prescription from a qualified eye-care professional. A contact-lens prescription is different. Copy the eye labels, numbers and plus or minus signs exactly. Do not round a value, combine SPH and ADD, or convert a cylinder prescription yourself.
| Field | What it means | What to provide |
|---|---|---|
| OD / R; OS / L | Right eye; left eye | Keep each value with its correct eye. |
| SPH | Sphere power | The complete power and its sign. |
| CYL & AXIS | Astigmatism correction and orientation | Both values when prescribed, copied exactly. |
| ADD | Additional near power | The prescribed ADD for progressive or other near-vision designs. |
| Prism & Base | Prism correction and direction | All prescribed prism values, directions and eye labels. Ask us to confirm the order before payment. |
If a value is unclear or missing, ask your prescriber. We can explain the order fields but do not perform an eye examination or prescribe a correction.
Which lens type should I choose?
Single vision
One correction across the lens, selected for distance, reading or another prescribed working distance. Astigmatism can be incorporated when specified. Use a reading prescription supplied by your prescriber instead of calculating one yourself.
Progressive lenses
Progressives combine distance, intermediate and near zones. Suitability depends on your prescription, frame size and fitting measurements. Contact us for the available design, price and fitting requirements if the product configurator does not offer a progressive option. Do not order frame-only or a different lens type expecting it to be converted automatically.
Prism prescriptions
WOOglasses can support prism orders, subject to prescription and frame review. Send the complete spectacle prescription through the agreed private channel and obtain confirmation of availability and price before paying. A prism entry without the base direction is incomplete.
PD and fitting measurements
Pupillary distance (PD) is the distance between pupil centres in millimetres. A single PD is a total measurement; dual PD gives separate right and left measurements. Distance and near PD can differ. Ask your eye-care professional for the measurement appropriate to the lenses you need; do not guess or use a frame dimension.
Progressive lenses may also require fitting heights measured with the selected frame sitting correctly on your face. Prism and complex prescriptions may require further checks. Ask us which measurements are needed before ordering. We do not use an assumed fitting height for a custom order.
Understanding lens index
A higher refractive index can allow a thinner lens for the same prescription. Final thickness also depends on frame size, lens shape, prescription, centration and material. Index alone does not establish impact resistance or UV protection.
Choose among the indices actually offered for your frame and lens design. The price displayed in the configurator or confirmed in your quotation applies. We do not promise a fixed percentage of thinning, or that every index is available for every prescription. Ask us for advice when your prescription is strong or your frame is unusually large.
Coatings, blue-light filters and sunglasses
Check the specific product and selected lens option for included coatings and any upgrades. Anti-reflection coatings reduce surface reflections; scratch-resistant coatings do not make lenses scratch-proof. Availability, UV performance, polarisation and tint must be confirmed for the actual product.
Blue-light filtering lenses
A blue-light filter is an optional lens feature where offered. We do not guarantee that it relieves eye strain, improves sleep or prevents eye disease. For screen discomfort, review your prescription and working conditions with an eye-care professional.
Sun lenses and driving
A dark tint or polarisation alone does not establish UV protection. Check the product's stated UV rating, filter category and driving limitations. Some photochromic lenses darken differently behind a windscreen. Do not use sunglasses to look directly at the sun. Fashion and sports styling does not establish certification as protective eyewear.
Before you place your order
- Check frame measurements and the required lens type.
- Provide your complete current spectacle prescription and the requested PD and fitting measurements.
- If your exact prescription or lens combination is unavailable online, obtain confirmation and a quotation before paying.
- Check the eye values, lens choices, complete price and delivery address before checkout.
- Keep your order confirmation. Contact us promptly if anything needs correcting.
All orders, including prescription glasses and customised lenses, have a combined processing and production time of 1–3 business days. Transit after dispatch is estimated at 7–15 calendar days for Standard Shipping or 5–10 calendar days for Business Express, for all supported destinations. See our Shipping Policy for estimates and charges.
When your glasses arrive
Check the frame and order details. Ask an optician for frame adjustments. If blur or discomfort persists, contact our support team and your eye-care professional. Stop using the glasses for driving or other safety-critical tasks if vision is unclear; seek prompt professional care for sudden vision changes.
Prescription/customised products may be excluded from change-of-mind returns. Faulty, incorrect or misdescribed goods retain applicable remedies. See our Returns & Refunds Policy.
