How do I find out what my prescription is?

You will need an up to date eye examination, at the end of this test your should be given a copy of your prescription.

We offer eye examinations at Chakshu London opticians, based within easy reach of Camden Town, Regent's Park and Primrose Hill. 

How do I send my prescription?

You can either upload a scanned image or photograph of your prescription when ordering or email to once you have placed your order. Please note that orders can not be processed until we have received a valid prescription.

What is pupillary distance (PD), and how do I get mine?

Pupillary distance (indicated on your prescription as PD) is the distance between the pupil centres of each eye, usually measured in millimetres. This is important for us to know in order to ensure you are looking through the optical centre of your lenses within the frame. This allows us to give you the best possible vision through your glasses. If this measurement is not included in your prescription, you can request it from your optician. 

However if you are unable to obtain this measurement, we would like you to follow this method of measuring your PD. 

What you need: 

A phone camera and a standard sized card (e.g. bank card/store loyalty card) 


Step 1: Hold the card below your nose (if using a bank card please ensure all private information is covered) 

Step 2: Hold your phone at arm's length to take a selfie, please ensure you look directly into the phone camera 

Step 3: Please email a copy of your selfie to, along with a copy of your prescription. 

Please note you will require a professional to measure your PD more precisely if you have been previously told that you have a squint (where you have an eye that turns in or out)

I require prism correction in my glasses, am I still able to order online? 

Currently we are unable to process prescriptions that include a prismatic correction.

Can I order lenses for any prescription online?

We currently offer prescription lenses online for anyone that has a SPH value no greater than +/-6.00 and a CYL value no greater than -2.50. Stronger prescriptions require more precise measurements to be taken. If your prescription is stronger than this, please visit us in store to order your glasses. 


What are polarised lenses? 

Regular sunglasses are tinted to reduce the amount of light that can pass through the lens to your eyes. In comparison, polarised lenses have a specially designed film to help prevent glare by limiting the direction of light that can pass through the lens. In particular, glare caused by reflection from water, snow and other light reflecting surfaces is cut out. 

A great asset for any skiers, fisherman and beach goers or even better if you're all three!

What are Sensity lenses? 

HOYA's Sensity lenses are 100% UV protected and are activated by UV light exposure and turn dark when you go outdoors and return to clear when you go indoors. They are great for people who spend a lot of time outdoors and don't want the hassle of having to swap from sunglasses to glasses.

Am I able to change the colour of the sunglass lenses?

You are able to choose between grey, green and brown tint colours online. In-store we have a wider range of tint colours available.

Can I find the same frames elsewhere?

Our varifocal glasses are designed in such a way that you have crystal clear vision at long distances, short distances and every distance in between. These special lenses avoid the need of swapping between two pairs of glasses. 

If you currently wear glasses for long distance and are finding that reading small text is getting more difficult or that you seem to be taking your glasses off to read more often then this is a sure sign that you need an additional prescription for near vision. This will be written as reading ADD in your prescription. 

To avoid having multiple pairs of glasses or constantly taking your glasses on and off, varifocals are the most convenient solution for you. Read more about varifocals here

I am having difficulty adjusting to my new varifocals glasses, what should I do?

Any new prescription can take a little while to adapt to however if you are having trouble adjusting to your new varifocals try these simple steps:With varifocals it is important to remember to point your nose in the direction you want to look at and lift your chin up slightly.
