Sunglasses combine fit, optics and materials. A designer frame may express a brand's style, but lens protection and optical clarity must be verified for the exact lens. UV protection should never be inferred from darkness or price alone.
02
How to choose
Check bridge fit, temple length, frame width and whether lenses sit close without touching lashes. Ask for written information on UV protection, polarisation where relevant and prescription options. Inspect hinges and nose pads; try the glasses in bright conditions if possible.
03
The Asia lens
High UV exposure in many Asian destinations makes verified protection especially important. Keep glasses in a rigid case in bags and vehicles, and avoid leaving them in a hot car where frames and coatings can deform. Ask whether local authorised optical service can replace lenses.
The short answers
Frequently asked questions
Do dark lenses block more UV?
Not necessarily. Lens darkness and UV filtration are different properties. Verify the manufacturer's protection specification.
Can designer sunglasses take prescription lenses?
Some frames can, some cannot, and lens replacement may affect warranty or fit. Confirm with the brand or an optician.
How should sunglasses be cleaned?
Rinse grit away when appropriate and use a clean microfiber cloth and lens-safe cleaner; dry wiping can scratch coatings.
