The ruler is great. It has a dual rule system; one is the standard 15cm rule which the other is between 20 to 40mm on both eyes. The standard rule allows you (with a friend) to take a binocular pupil distance reading and the other rule allows you (with a friend) to take a monocular pupil distance. (Binocular is the distance between your eyes // Monocular is the distance between your pupil(s) to the centre of your nose)
The monocular is ideally the one you should go for. It's said to be more accurate than the binocular in most cases. This came true for me as my right eye is 1mm more than my left eye. Had the binocular pupil distance had only been taken, it may have unforeseen caused vision issues.
Fit - As expected I'd recommend this product
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 03303 801 190 (Mon - Fri, 9am - 5pm) for further assistance.
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.
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.
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.
