Short answer: choose a spectacle frame that matches your face width, sits level without pinching, and is deep enough for your lenses (especially progressives). You can buy SPINEL Sterling frames online in Sri Lanka and have a SPINEL practitioner fit single vision or progressive lenses to them.
Read the numbers on the arm
Most frames have three numbers printed inside one arm, for example 52-18-145: lens width, bridge width and temple (arm) length in millimetres. Compare them with a pair that fits you well.
Choosing a material
- Acetate: rich colours that run through the material, adjustable with gentle heat, durable.
- Metal: thin and light, with adjustable nose pads.
- Combinations: acetate fronts with metal accents, like the gold details on Sterling Series 2.
Frames for progressive lenses
Progressives need enough depth below your pupil for the reading zone. Very shallow frames make reading harder. SPINEL’s Innosight design needs a minimum fitting height of 17.0 mm, which suits shallower frames. Your practitioner checks this before making the lenses. See the progressive lenses guide.
Buying frames online, then fitting lenses
- Choose a frame online and have it delivered anywhere in Sri Lanka.
- Bring a current prescription (ideally from the last 12 months).
- A SPINEL practitioner takes your measurements and recommends single vision or a progressive design.
- The lenses are made to order, then fitted, adjusted and checked before you take them home.
