How to Choose Your Frames
How to Choose Your Frames
Buying eyewear online is easy when you know what to look for. This guide walks you through everything — from reading the numbers on a frame to finding the shape that flatters your face.
📐 Understanding Frame Measurements
Every frame has three key measurements printed on the inside of the temple arm, written like this: 52 □ 18 – 140
| Measurement |
What It Means |
Where to Look |
| Lens Width |
The horizontal width of one lens, in mm. A smaller number means a narrower lens. |
First number (e.g., 52) |
| Bridge |
The distance between the two lenses across the nose. A wider bridge suits a broader nose. |
Second number (e.g., 18) |
| Temple Length |
The length of the arm from hinge to tip. Most adults fit 135–145 mm. |
Third number (e.g., 140) |
| Frame Width |
The total width of the frame front. Should roughly match the width of your face for a balanced fit. |
Listed in product details |
| Lens Height |
The vertical height of the lens. Important for progressive/bifocal lenses — taller lenses give more reading area. |

Frame Size (S / M / L)
The size label on each product (e.g., "size 55") refers to the lens width. Here's a general guide:
-
Small: Lens width up to 50 mm
-
Medium: Lens width 51–54 mm
-
Large: Lens width 55 mm and above
If you currently own a pair of glasses that fits well, check the numbers on the inside of the arm and use them as your reference.
👁️ Measuring Your Pupillary Distance (PD)
Your PD is the distance in millimetres between the centres of your pupils. It ensures your lenses are ground and centred correctly for your eyes.
How to measure your PD at home
- Stand 20–30 cm in front of a mirror in good lighting.
- Hold a ruler flat against your brow, with the zero mark aligned to the centre of your left pupil.
- Without moving the ruler, read the measurement at the centre of your right pupil.
- Repeat 2–3 times and take the average.
Most adults have a PD between 58 and 68 mm. Each product listing shows a PD Range — choose a frame whose range includes your measurement for the best optical result. Your optician can also measure your PD precisely.
💊 Prescription Range
Each frame lists a Prescription Range (e.g., –6.00 to +4.00). This is the diopter range the frame can comfortably accommodate.
- Stronger prescriptions (higher diopter values) produce thicker lenses. Smaller lens widths minimise this effect.
- If your prescription is outside a frame's listed range, the lenses may be too thick or optically distorted at the edges.
- When in doubt, consult your optician before ordering.
🔷 Matching Frame Shape to Face Shape
The right frame shape can balance and complement your natural features. Find your face shape below:
Round Face
Soft, curved features with similar width and length. Angular frames — like Square or Rectangular styles — add definition and make the face appear longer and slimmer.
Square Face
Strong jaw and broad forehead with similar width and length. Round or oval frames soften the angles and add contrast to sharp features.
Oval Face
Balanced proportions, slightly wider at the cheekbones. The most versatile face shape — almost any frame works. Try bold styles like Pilot or Cat-Eye to make a statement.
Heart Face
Wider forehead tapering to a narrow chin. Bottom-heavy or rimless frames draw attention downward and balance the forehead. Avoid top-heavy or decorative brow-line frames.
Diamond Face
Narrow forehead and jaw with wide cheekbones. Cat-Eye or oval frames highlight the cheekbones and soften the overall look.
Oblong / Rectangular Face
Longer than it is wide, with a straight cheek line. Oversized or deep frames add width and break up the length. Pilot and round styles work especially well.
🛠️ Frame Materials & Weight
Comfort over long wear depends on material and weight:
-
Acetate — Lightweight, hypoallergenic, and available in rich colours and patterns. A popular choice for everyday wear.
-
Metal (titanium, stainless steel) — Slim, durable, and adjustable. Ideal for a minimalist look.
-
TR-90 / Nylon — Extremely lightweight and flexible. Great for sport or active use.
Each product listing shows the frame weight in grams so you can compare before you buy.
