Description

An oversized, gently angular square frame in flexible TR90 material, shown here in sheer blush pink, solid black, and translucent smoke-grey. The clear lenses carry a blue-light-filtering coating that shows as a faint blue glint under direct light, set off by slim gold-tone hinges at the temple. The oversized shape sits slightly forward off the face, giving a bit of breathing room around the eyes rather than the tight fit of a smaller frame. Between the flexible build and the soft, wearable colourways, it's designed to survive being worn most of the day at a desk without pinching at the temples or nose.

Composition & Care

Flexible TR90 frame (printed on the inner temple) with clear, blue-light-filtering lenses and metal spring hinges. Clean with a microfibre cloth — the anti-blue-light coating sits on the lens surface and can dull if wiped with a dry cloth or clothing, so add a drop of lens cleaner if lenses look smeared. TR90 is bend-resistant, but avoid folding the arms past their natural range, and the metal spring hinges mean a small amount of flex at the temple is normal rather than a sign of a loose screw.

Delivery & Returns

Free UK delivery. Returns accepted within 30 days in original, undamaged condition.

Sustainability

TR90 is a lightweight, highly durable plastic that resists snapping under everyday flexing, so this frame is built to outlast a rigid acetate pair that cracks under the same stress. Because the material flexes rather than fractures, a frame that gets sat on or squashed in a bag is far more likely to spring back into shape than to need replacing outright.

People Also Ask

A few things worth knowing before you buy the Photochromic Blue-Light Glasses — from fit and styling to care and delivery.

Do these have a prescription, or are the lenses just clear?

The lenses are plain, non-prescription clear lenses with a blue-light-filtering coating — they don't correct vision, they're designed to sit in front of a screen. If you need vision correction, an optician can usually fit prescription lenses into a similar TR90 frame separately.

How can I tell the coating is actually working?

Tilt the lens under a bright light or your phone torch — you'll see a faint blue-violet sheen across the surface, which is the coating reflecting blue wavelengths rather than letting them through. That same sheen is a useful way to check the coating hasn't worn thin after months of wear.

Which colour runs true to the photos?

All three — the blush and smoke-grey frames are semi-translucent so you can see colour depth, while the black is fully opaque; the gold hinge hardware is the same across all three. The semi-translucent finishes photograph slightly lighter than they look in person, so expect a touch more saturation in hand.
