We spend more time staring at screens than we’d probably like to admit. Phones, tablets, laptops and e-readers have become our companions from breakfast to bedtime, glowing at us with endless to-do lists, emails and entertainment. All that time spent in front of screens brings with it one small modern nuisance: blue light.

Blue light sits at the high-energy end of the visible spectrum. It’s what makes screens appear crisp and bright, but it also contributes to eye strain, dryness and fatigue. Spend a long day moving between screens and you’ll know the feeling; gritty eyes, a dull headache, and that faint sense of being slightly over-lit.

This is where blue light blockers come in. They’re not a miracle cure, nor are they a medical necessity, but they are a clever little comfort tool. Blue light lenses soften the harshness of your screens, reducing glare and helping your eyes relax. Many people also find that filtering blue light in the evenings helps them switch off more easily - less digital glare, more calm before bed.

At Renley Hawthorn, we love products that quietly improve the everyday, which is why Barner’s range of blue light reading glasses from Barcelona caught our attention. They manage to balance style with substance; a rare thing in the world of eyewear. The frames are made from TR-90, a strong yet feather-light material that’s comfortable enough for all-day wear. The lenses are CR39, known for their clarity and durability. They come in both prescription and none prescription versions. And each pair comes tucked inside a soft neoprene case that keeps them protected whether they live in your work bag or by the sofa.

Barner’s designs have that easy European charm, a touch of colour here, a clean line there, and they feel reassuringly well-made. Slip a pair on during a long afternoon of emails or a late-night scroll, and you’ll notice the difference almost immediately.

Blue light glasses won’t change your life, but they might just make your day that bit more comfortable. A small, simple upgrade to how we live with our screens — and one that looks rather good while doing it.
