KANASTAL Large Over-Glasses Sunglasses, TR90/TAC, UV400, Polarised (except yellow)

The large, square format is designed to sit over prescription glasses, giving you a single pair of sunglasses for outdoor wear without removing your usual spectacles.

TR90 and TAC construction, a UV400 specification and a choice of colours make these a practical style-led option for everyday outings.

The range is listed as polarised except for the yellow option. It is aimed at men and women, with driving, travel and daily wear among its intended uses.

What you’ll notice day to day

The over-glasses design is the defining feature: keep your prescription glasses on and wear these over them when heading outdoors. That makes them a useful alternative to switching to prescription sunglasses, particularly if you want a separate pair for changing light or travel. The large square shape gives them a clear, oversized look rather than the appearance of a compact frame.

The product is described with TR90 and TAC materials and a UV400 specification. Polarisation is listed for the options other than yellow, so the colour you choose matters if polarised lenses are important to you. For a journey by car or time spent outside, the sunglasses can be worn over your regular glasses, for days when you want a smaller frame or one pair to replace your spectacles, a different style may suit that routine better.

Buyers often comment positively on the appearance and say the sunglasses fit over their glasses. Some also report that they stay in place, while others appreciate the style. These are individual customer impressions, but they reflect the practical appeal of a frame intended to be worn over spectacles.

Worth noting

The unisex design is presented in a large, square shape and a multicolour range. The over-glasses format is especially relevant if you normally wear prescription spectacles and want sunglasses that can be layered over them. It offers a different approach from buying a second pair of prescription lenses: keep your usual glasses in place and add this pair when needed.

TR90 and TAC are the materials named for the product, while UV400 and polarisation are the listed lens features. The yellow option is the exception to the polarised specification. If you are choosing by lens feature as well as colour, bear that distinction in mind when selecting an option.

Everyday use

These sunglasses are intended for everyday wear as well as driving and travel. For a day out, you can put them on over your regular glasses when moving outdoors, then take them off when you no longer need sunglasses. Their large format is the key consideration when comparing them with standard sunglasses: the design is made to go over spectacles, rather than simply replace them.

The product is also described as stackable, which may suit someone who likes to organise accessories together between outings. The overall emphasis is straightforward: a distinctive square style paired with an over-glasses format, for people who want to keep their usual spectacles in use while adding sunglasses.

Is it worth it?

If you wear prescription glasses and want a separate pair of sunglasses to wear over them, the large KANASTAL design addresses that need directly. The square shape, TR90 and TAC materials, UV400 specification and polarised options (except yellow) give you clear points to weigh up alongside colour and style. It is a practical choice for everyday outdoor use, travel or driving when keeping your regular glasses on is part of the routine.
