In summary: free for many, £21.43 for the rest. That’s in England. In Wales or Scotland, count your blessings. The test is cheap, the glasses are expensive, and the puff is hilarious. Don’t skip it—your eyes are the only ones you’ve got. Unless you’re a lizard, in which case, carry on.
Now go book. Your future self, squinting at a bus timetable, will thank you. And if you spy a pair of £500 designer frames? Just blink. They’ll still be there tomorrow. But your £21.43 eye test won’t last forever. Go while the price is right.
