Classic metal Rectangle

If you are not sure what suits you, start here. A slim rectangular stainless-steel frame is the most forgiving shape there is — it flatters round, oval and square faces alike, and reads as smart rather than fashionable, which matters if these are your everyday work glasses.

The nose pads are adjustable, so the fit can be corrected in seconds if the frame slides. Spring hinges take the strain when you push them onto your head.

The price shown includes standard single-vision lenses. Choose blue-cut if you are on a screen all day, or progressive if you need both distance and reading in one lens.

Usually cut and fitted within the hour in single vision. Progressives take two to three working days.
