I earlier asked, and was confused, by the suggested requirement for an eye test, before you could renew your driving licence.
I was under the impression that it would require some special eye test, not that I was worried I might fail, rather that I was keen to make sure I could actually fit it all in in time. I had my annual test, just a few weeks ago, so I knew I was OK.
I've just received my licence renewal form. It is slightly different to the last one, but it's a 'self declaration', that your health, and eye sight if good enough to drive.
The paper form, is the easy option, though they suggest better to renew online. The online option is a new beta, and absolutely horrendous. The paper form is 'busy' enough, but quicker to complete.
It didn't request a new photo, much to my surprise.
