How to Choose Sunglasses in South Africa: UV, Polarisation & Fit

A practical South African guide to choosing sunglasses for UV protection, polarised glare control, frame fit, lens tint and everyday use.

South African light can be hard on your eyes, whether you are driving across Johannesburg, walking near the coast or spending a weekend outdoors. The best sunglasses are not simply the darkest pair. UV protection, glare control, fit and lens quality all matter.

1. Start with UV protection

Choose sunglasses that block both UVA and UVB radiation. A dark tint alone does not prove that a lens offers UV protection. The American Academy of Ophthalmology recommends sunglasses that provide 100% UV protection, and notes that the colour or darkness of the lens is not what determines that protection.

Every pair in the Aweh Eyewear sunglasses collection is selected for UV-A and UV-B protection. Product pages also identify the model, size, lens colour and frame details so that you can compare like with like.

2. Understand what polarised lenses do

Polarised lenses reduce reflected glare from flat surfaces such as roads, water and car bonnets. That can make them especially useful for daytime driving, fishing and outdoor activity. Polarisation and UV protection are different features: a lens can be polarised without automatically providing adequate UV protection, so check both.

If glare reduction is your priority, browse polarised sunglasses or the accessibly priced Move sunglasses range.

3. Match the frame to how you will use it

Everyday and smart-casual wear: classic shapes such as Aviator, Wayfarer, round and square frames are easy to wear across different settings.
Running, cycling and active use: look for a secure fit, good side coverage and a frame that stays comfortable when you move.
Driving: prioritise clear vision, glare reduction and a comfortable temple fit that does not press behind the ears.
Long outdoor days: larger lenses or wraparound shapes can reduce the amount of light reaching the eyes from the side.

For classic lifestyle frames, compare the Ray-Ban sunglasses collection. For sport-influenced and wrapped designs, explore Oakley sunglasses.

4. Use the measurements, not only the photo

Two frames that look similar online can fit very differently. Check the lens width, bridge width and temple length when those measurements are listed. If you already own a comfortable pair, look for the three measurements printed inside its temple arm and compare them with the new frame.

A frame should sit securely without pinching the temples, sliding down the nose or touching the cheeks when you smile. Wider is not always more comfortable; the bridge and temple shape matter just as much.

5. Choose a lens tint for comfort and contrast

Grey lenses generally preserve natural colour balance, while brown or amber lenses can increase perceived contrast. Gradient lenses are darker at the top and lighter below, which many people like for mixed indoor and outdoor use. The best choice is personal, but UV protection remains essential regardless of tint.

6. Check authenticity, returns and delivery

For branded eyewear, use the full model and colour code when comparing products. Aweh Eyewear lists genuine branded stock, including Ray-Ban, Oakley, Vogue, Arnette and Move, and delivers across South Africa. If the fit is not right, the store offers returns within 30 days, subject to the published return conditions.
