The right lenses make every view better.
Understand common spectacle lens types, lens index and coatings before you choose. Your prescription, frame and daily needs all matter.

These are common categories. The suitable option depends on your prescription and an optometrist’s recommendation.
Single vision
One lens power across the lens, commonly prescribed for distance or near vision.
Bifocal
Two distinct viewing areas, typically distance and near, with a visible segment boundary.
Progressive
A gradual power change for distance, intermediate and near tasks, without a visible segment line.
Reading lenses
Near-vision correction prescribed for reading and other close work when appropriate.
Computer / occupational
Designed around specific working distances and tasks. They may not replace general-purpose glasses.
Plano lenses
Non-prescription lenses with no vision-correction power. Coatings and UV properties vary by product.
What does lens index mean?
Refractive index describes how strongly a lens material bends light. Higher-index materials can often achieve a thinner lens for the same prescription, but the final thickness also depends on frame size, shape, lens design and prescription.
| Common index | General description | What to consider |
|---|---|---|
| 1.50 / 1.56 | Standard or mid-index options | May suit some lower prescriptions; material availability varies. |
| 1.60 | High-index option | Can reduce edge or centre thickness in suitable prescriptions. |
| 1.67 | Higher-index option | Often considered for stronger prescriptions where appropriate. |
| 1.74 | Very high-index option | May offer a thinner profile for selected high prescriptions; not automatically the best choice for everyone. |
Understand the common add-ons.
Anti-reflective (AR)
Reduces reflections from lens surfaces and can improve visual clarity and appearance in many situations.
Scratch-resistant
A hard coating can improve resistance to everyday surface scratches. No spectacle lens is scratch-proof.
UV protection
Helps protect the eyes from ultraviolet radiation when the lens is specified and verified for the required UV protection.
Photochromic
Darkens in response to UV and/or light conditions, depending on the product. Performance varies by design and environment.
Polarised
Commonly used in sunglasses to reduce glare from reflective surfaces such as roads and water.
Blue-light filtering
Products differ in how much blue-violet light they filter. Evidence that these lenses prevent digital eye strain is limited; screen habits and regular breaks matter.
Keep these details ready.
Your prescription
SPH, CYL, Axis and ADD (if prescribed), with the right and left eye clearly identified.
Your PD
Pupillary distance, measured accurately for lens centration. Some prescriptions may include monocular PD.
Your frame
Frame size, shape and fitting position can affect lens thickness, weight and suitability.
