The truth about UV-blocking contact lenses

There’s no doubt that contact lenses are great. But even contacts with built-in UV protection aren’t enough to keep your eyes safe in the sun. Here’s why.

It’s that time of year when we’re all flocking to our nearest beach, pub garden or outdoor pool to catch some precious rays. But while packing sun block and a sun hat is (hopefully) standard procedure for most of us, it’s important to remember that our eyes also need protection.

In fact, our eyes are ten times more sensitive to UV than our skin, but only 7% of the population are aware of the risks to their eyes¹.

UV protection contact lenses

If you wear contact lenses, you might feel reassured by their UV protection (if they have it). But while UV-blocking contact lenses provide good protection to the insides of the eyes, it's also important to look after the outsides of the eyes and eyelids too.

Even though light takes more than 8 minutes to travel from the sun to the earth and pass through our protective atmosphere, its power is still considerable. Alongside the visible light spectrum, sunlight also contains two bands of invisible ultraviolet (UV) light: UVA and UVB.

UVA has been linked to eye conditions including cataracts and macular degeneration. UVB may help to increase our vitamin D levels, but it’s also the prime cause of sunburn – and it can harm our eyes too.

Both types of UV light are harmful to our eyes. Unless we protect them with suitable UV-blocking sunglasses, we risk damaging our sight.

How else can I protect my eyes?

The best way to protect your eyes from UV damage is to wear sunglasses. While UV blocking contact lenses do offer protection, coverage is limited. Sunglasses cover a much greater area of the eye, including the sensitive skin around the eyes.

But it’s not as simple as picking up a pair of cheap sunnies, you need them to guard you from harmful UV rays. Check for ‘CE’ marked UV400 lenses, or British Standards BS EN ISO 12312-1:2013, this will guarantee you a safe level of UV protection. These lenses obscure around 99-100% of UV rays and offer the ultimate level of protection.

What the Government’s road safety proposals could mean for your eyesight
In January 2026, the UK Government published proposals as part of its Road Safety Strategy, including a consultation on whether drivers aged 70+ should have mandatory eyesight checks. Nothing has changed yet. This is a consultation, which means the Government is asking for views before deciding what happens next. Still, it is a useful reminder that good vision is a key part of safer driving, for you and everyone around you. If you want reassurance about your eyesight for driving, we can help. Book an eye test What’s being proposed for drivers aged 70+? The Government is consulting on the idea of introducing regular eyesight testing for drivers aged 70 and over as part of licence renewal. The aim is to reduce risk linked to age-related changes such as: gradual changes in sharpness of vision reduced contrast sensitivity (seeing clearly in low light) greater sensitivity to glare slower reaction times and other health factors that can affect driving Key point: These are proposals, not new rules. No extra testing has been introduced at this stage. Driving eyesight standards: what applies right now? Current legal eyesight standards still apply to all drivers, whatever your age. The Road Safety Strategy proposals also reinforce increased use of roadside eyesight checks by police. If a driver fails a roadside eyesight test, the DVLA may take action, including removing a licence. If you are unsure whether you meet the standard, an eye examination is the simplest way to check and get clear advice. Check my vision for driving Struggling with glare at night? You’re not alone The proposals also highlight research showing many drivers have reduced or stopped night driving due to headlamp glare, with brighter LED headlights and taller vehicles thought to contribute. If night driving feels harder than it used to, it could be down to: a change in your prescription early lens changes in the eye dry eye glare sensitivity or reduced contrast An eye test can help identify what is going on, and we can talk through practical options such as lens choices and coatings designed to improve comfort when driving at night.
