Black Rectangle Sunglasses

The Kensington keeps things sharp and understated. These black rectangle sunglasses use a slim, clean-lined frame that flatters rounder and fuller faces by adding angles and length, which is part of why the rectangle shape is such a dependable choice in black mens sunglasses. The deep glossy black acetate is smart enough for work and relaxed enough for the weekend, so it earns its place as a do-everything pair.

Polarised UV400 lens protection

Behind the styling sits a proper polarised UV400 lens. Polarisation cancels out the glare thrown back by roads, water and bright pavements, while the UV400 rating blocks 100% of UVA and UVB rays. For driving in particular, that drop in glare makes a real difference to comfort and clarity on a bright day, and the neutral grey tint keeps colours natural rather than over-darkened. The Kensington is sized for a comfortable medium-to-large fit, with sprung hinges that flex to suit most face widths and a lightweight build that stays put without pinching. The slim black frame is endlessly versatile and pairs with everything from a suit to a t-shirt.

Trusted Customer Reviews

Alice Young, Northampton

Delivery was earlier than estimated, which was a lovely bonus. The glasses look stylish and have a good, sturdy feel to them. The build quality is impressive and they look great, too. Very satisfied overall.
Amy Robinson, Swindon

Really impressed with these reading glasses — I honestly didn’t expect them to be this good. I own more expensive optical frames, and these are actually better! They look stylish, feel great, and exceeded my expectations. I loved them so much I immediately ordered a second pair.
Claire Wilson, Edinburgh

My local opticians were so overpriced so i decided to try Just Glasses instead, and I’m really glad I did. They’ve been brilliant for reading my book or doing a bit of sketching, and they’re great to have on hand for everyday use or when I’m away for the weekend. Superb value, and I’m delighted with them.
David Thompson, Worcester

The best reading glasses store online. Unbeatable value for money and simple to order. I always order the same blue pair, and the delivery is nice and quick. I would highly recommend them.
