The patches apparently blur things beyond a few metres but leave close vision unaffected. Optically, I’m not exactly sure how they can achieve this, reading glasses would achive this but you can’t stick them on on top of your regular prescription.
If you’re visiting Israel on holiday I’d be interested to see these things so see if you can pick up a set. They seem to be selling for about £5 but if you’re from Scotland you’ll know that’s only the price to start haggling from.
