How to choose glasses that suit your face

Choosing frames in a shop can be tricky. You are often on your own and will probably be pushed towards the designer frames with the highest profit margins anyway!

We have given you a guide as to face shape and which frame shape will suit your own face shape, but it is only a guide.  You might know an oversized square plastic frame is exactly what you want, even though the guide tells you otherwise. You are the master, YOU choose what YOU like. Fashion doesn’t always follow the rules!

However! If you have a higher prescription, choosing the smallest frame you can, while still fitting your face and head, will give the best cosmetic result for your lenses. With higher prescriptions, keeping your pupil as central in the frame shape in both the horizontal and vertical axis will make your lenses look the best. If you are a high minus (short sighted) wearer, avoid wrapped sports style frames such as Oakley. If you are a high plus (long sighted) wearer, you don’t want to be choose very flat fronted frames – fortunately there are not too many frames on the market with very flat fronts. Also, for any higher prescription, plus or minus, plastic frames disguise lens thickness more than metal frames.

The basic guide –’s only a guide!


You have a round face if you have a smooth outline to your face, full cheeks, a chin that sweeps smoothly round from the line of your cheeks and a rounded forehead.

As your face is round, you will want to try and lengthen the face to balance it and the best way to do this is with wider and angular frames.


This is considered to be the ‘perfect’ face shape. Everything is in proportion and the face usually appears slightly longer than it is wide.

You are lucky, pretty much any frame will suit you! The only advice is to avoid frames narrower than the widest part of your face. Go for the same width or slightly wider than the widest part of your face. Any shape will be great!


Square faces have strong angles at the jaw, which can often be the widest part of the face, and also a square chin. Width and length equal to each other but be careful not to confuse this as being round.

You are looking to soften your face. Oval or round frames will help with this. It is best to avoid large square frames.


Similar to heart shaped, defined by a wider forehead and a tapered jawline continuing to a pointed chin. Heart shaped has a slightly wider eye and cheek area than triangular. Triangular shaped faces tend to have the main facial features narrower than the jaw.

You will be trying to balance out the narrower lower part of your face, so avoiding semi-rimless frames is a good idea as all the visible frame is across the brow line. Rimless would be good for you, or any frame that is wider at the bottom than the top, but they are harder to find.


A narrow forehead and chin with very prominent cheekbones. The rarest face shape.

Because you have very prominent cheekbones, you will want to try to bring more attention to the eye area to balance everything out. Bold frames and colours can work very well. Also, deliberately over-sized frames can often be very effective.


The face appears much longer than it is wide. The chin area is usually quite prominent.

Any frame that widens the appearance of the face will be good here. A large, square frame can quickly shorten the appearance of the face which is what is required to balance the face.

Will they fit if I buy online?

This is what a dispensing optician would measure and advise you on. We advise you to measure your existing glasses or, if  you don’t already wear glasses, find some in a shop you like the fit of and note down the measurements of those to find a similar size online here at Simplespex. The glasses measurements are usually found on the inside of one of the sides and will look like this 52-18-135.

’52’ is the diameter from bridge to temple of one eye aperture in mm.

’18’ is the bridge measurement across the nose, the distance between the two eye apertures in mm.

‘135’ is the length of the side/arm from the front of the frame  to the end tip. (This measurement is not always on the frame)

If you receive your glasses and they are not quite tight enough or too tight, high street opticians will adjust them for you for a small fee. Even with that small fee you will still be saving a fortune on the high street price of glasses.
