Quality sunglasses protect your eyes from harmful ultraviolet radiation and improve comfort in bright conditions. The right pair also reduces glare and supports clear vision for driving and outdoor activities.
Key Features
Look for lenses that block 99-100% of UVA and UVB rays and carry recognised certification. Polarised lenses reduce glare from reflective surfaces such as water and roads but are not essential for ultraviolet protection.
- Wraparound or larger frames offer better coverage at the sides
- Lens tint depth does not always reflect ultraviolet blocking ability
- Photochromic lenses darken in bright light but may be less effective in cars
- Prescription sunglasses or clip-ons may be needed if you normally wear spectacles
Fit and Use
Comfortable, well-fitting frames encourage regular wear, which is particularly important for children and people following eye surgery. Sunglasses should complement, not replace, wide-brimmed hats and shade where possible.
- Ensure frames do not slip down the nose or press uncomfortably behind the ears
- Choose impact-resistant materials for sports or active use
- Replace heavily scratched lenses that compromise clarity
- Encourage children to wear suitable sunglasses from an early age
