Wearing larger frames with the right lenses is what we should aim for most of the time – not just for bright direct sun exposure. “Up to 80 per cent of UV radiation penetrates cloud cover and UV exposure occurs year-round, even on cold or overcast days,” Dr Zamani says.
Sunlight carries three types of ultraviolet radiation – UVA, UVB and UVC – though only the first two reach ground level and UVB is generally considered the more damaging of the pair. Both are present whether or not the sun is actually visible and both raise the risk of conditions that affect eyesight over time: cataracts, pterygium, photokeratitis, eyelid cancers and some age-related macular degeneration. Most of this is preventable with consistently good eyewear.
Health issues aside, there’s the cosmetic effects of sun damage around the eyes too. Using SPF in the area is non-negotiable and can help with protection against sun damage, but squinting against bright light can contribute to the formation of accelerated lines around the eyes over time too. Larger frame styles let the muscles around your eyes relax instead of working overtime.
How to choose sunglasses that actually protect you
UV400 is non-negotiable
The lens must block wavelengths up to 400 nanometres, which means 100 per cent of UVA and UVB. “Look for the UV400 label and a CE or UKCA mark” says Rufus Abbott, owner and creative director, Eye Club opticians and Eye Club & Co.
Size matters
“The lens should cover the eye socket generously, sitting close to the brow and cheek. Wrapped or deeper styles stop the light leaking in from the sides and above,” Rufus says.
Consider lens categories
Category 1 and 2 lenses suit overcast, cloudy or mixed weather conditions. Category 3 is for bright days and sunny destinations. Category 4 is reserved for high-altitude mountains and open water (but note that they aren’t legal for driving).
Think about polarisation
The colour of your lens doesn’t matter or add protection. But a polarised finish is something to consider. “A polarised lens filters out horizontally reflected glare – the harsh rays bounce off water, wet roads, sand and car bonnets. It does not add UV protection on its own, but it transforms visual comfort, cuts squinting and eye strain, and lets you keep sunglasses on all day, which is ultimately what protects you,” says Rufus.
Keep them on
Try not to take them off during the day, unless you’re inside. Getting frames fitted properly is ideal to prevent them feeling too tight or sliding off, and means you can wear them comfortably.
