5th February 2020

I ordered 2 pairs of glasses unfortunately i cant wear either as i cant see correctly through them even though i sent my prescription through, i took them to a local optical shop, and they said they were not a good match to my prescription so i should not wear them, which is a shame because i liked the fames and i have wasted £100

Fit - Moderately large I wouldn't recommend this product

SelectSpecs US says...
Julie, I can confirm we have made both pairs to the correct Bifocal prescription, it is unlikely that both pairs would have an error. Looking at your order, we do note that an Average PD (63mm) was selected, for your prescription we would recommend checking to ensure this value matches your prescription as this could be the reason why you are experiencing an issue. Once you have confirmed this, please contact our customer services team so we can get this resolved for you. Thank you.

very happy very comfy

Fit - As expected I'd recommend this product

  Lightweight reading glasses

27th August 2018

Glasses fit comfortably, the lens is brilliant with my new prescription and they are really light to wear. I particularly like the colour and semi rimless frame. The only downside for me relates to putting them in a case when I am not reading, because the arms do not fold as flat as other frames

Fit - As expected I'd recommend this product

  Great service. Frames not quite right

3rd February 2018

Great quality, value and service. Frames were smaller than anticipated and have a slight winged, V shape across face, which was hard to tell from pictures on website. It would be good if you had some function to try glasses digitally eg from uploading a photo of your self and then choosing frames. Have seen it elsewhere. Will still buy glasses from here as generally am very happy -apart from difficulty in selecting the right frame and size for face.

Fit - Too small I'd recommend this product

  Not bad

28th May 2017

The only thing I don't like is the lenses width, if it was slightly slightly smaller that would be nice but besides that it's nice and fancy

Fit - As expected I'd recommend this product

Help with frame sizes

Finding the correct frame size to suit you requires you to know a little about the different measurements that are used.  Size information is normally broken down in to arm / temple length (ranges between 120 - 150mm), bridge width (ranges between 14 - 24mm, and lens width (ranges between 40 - 62mm).  We also include a frame height measurement where possible, this can vary depending on frame style.

If you require further help, please do not hesitate to contact our customer service team on (646) 878-6195 (Mon - Fri, 9am - 5pm GMT) for further assistance.

I already have glasses, how do I find out their size?

If you have a pair of glasses that are a perfect fit, you can usually find the frame size information on the frame - usually on the arm or the bridge.

Size Guide - Frame Dimensions

What to look for?

What to look for?
You will often find a variety of information on the frame, including model number, branding and frame sizing. The numbers you are looking for will be similar to this format 150 - 22 - 50 although this can vary from manufacturer to manufacturer.  These numbers provide the following information:-

150 - Arm / temple size (in mm), a 3 digit value normally ranging from 120 - 150.
22 - Bridge size (in mm), a 2 digit value normally ranging from 14 - 24.
50 - Lens width (in mm), a 2 digit value normally ranging from 40 - 62.

I want a size that's not listed

We do our best to ensure we stock all available items from all our supplied brands so if an item is not listed it may be out of stock or discontinued. If you do not see the frame size you require please contact us through our Customer Services system where we will try to assist you.
