Prescription Sunglasses

Download a voucher of D&A website and get a test for a tenner. I had one a couple of months ago at big branch on regent Street and they did a loads of tests for eye health, blind spots etc. before I even got to see the optician for the eyesight test itself.

They only give you the standard prescription data to take away but apparantly if you really want you can hit them with an FOI request and get a copy of results of every test plus your PD and then email that info to an optician in Hong Kong and get glasses made up for £20.

+1 for D&A.
