Am I actually allowed to drive with only one eye operated on and the other still cloudy?

Nobody will give me a straight answer on this and I am starting to think they are all avoiding it deliberately.

First eye done four weeks ago, second one not until late November. The new eye is excellent. The old eye is like looking through a net curtain that somebody has been smoking next to for a decade. Together they produce something I would describe as "mostly fine, occasionally alarming".

The discharge letter said do not drive until your vision is adequate and you feel confident, which is the sort of sentence that means nothing to a man standing in a car park holding his keys. Adequate according to whom? Is there an actual test, or is it genuinely just vibes? And does the cloudy eye drag me below the standard even though the good one is now sharper than it has been in years? I do not want to find out the answer from an insurance company after the fact.

Not vibes, but not as precise as you would like either. From what I was told during my own gap the standard is about what you can read with both eyes open together, wearing whatever glasses or lenses you normally wear, not eye by eye. So a good eye can carry a poor one to a large extent. That is why plenty of people drive perfectly legally with one bad eye for years without anyone stopping them.

The catch is that legal and comfortable are two separate questions and only one of them is written down anywhere. I was legal well before I was comfortable.

What I did, and it cost me nothing: I booked in with my optometrist in the gap and simply asked her to check me against the driving standard and tell me straight. Ten minutes. She said yes for daylight, and told me to leave the dark alone until the second eye was done, which was fair because I had already worked that out myself on a wet Tuesday.

Ken, your clinic can also confirm at your review. Ask the actual question out loud rather than hoping the letter answers it. They are used to it.

Ken, I want to answer this carefully, because it is the question I was most anxious about myself and I got very little help with it at the time.

I am a patient, not a clinician, so take the practical shape of it rather than a ruling. The three things I eventually understood were these. First, the driving vision standard is a threshold you meet or do not meet, measured with both eyes together and with your usual correction on, so an excellent operated eye can genuinely carry a cataract in the other. Second, meeting the threshold is necessary but it is not the whole of it, because the letter also asks you to feel confident, and that second half is not a formality. During my own gap I was almost certainly legal for a fortnight before I was safe, and I knew it, because my glasses no longer suited either eye and the world had gone strangely flat. Third, and this is the part I would actually act on, the people who can tell you are your clinic at your review and your optometrist, and the licensing authority publishes the standard itself. Ring them. It is a five minute call and it removes the exact worry you are carrying about the insurance company.

What I did in the end was drive short familiar daylight routes, the shops and my sister's, with my husband beside me for the first two, and I left night driving alone entirely until the second eye had settled. That is not a rule, it is just what a nervous woman with one good eye did. The site's guide to driving after cataract surgery sets out how the standard and the confidence question fit together, and coping while you wait for cataract surgery has more on getting about in the meantime.

One thing I would gently push back on in your post: do not treat this as a box to tick before you get your keys back. If a junction makes you sweat, that is information, and it does not stop being information because a chart said you passed.

Belated report. Optometrist checked me in the gap as June suggested, I met the standard comfortably with both eyes open, and she said the same thing about the dark. So I drove days, not nights, and did not sit at home sulking for six weeks.

Second eye done on the 26th of November. Drove to my daughter's in the dark last Saturday, motorway and everything, and it was the first time since about 2022 that I have done that journey without gripping the wheel. Still get rings round the headlights with these multifocals but that is a different thread and I have already bored everyone with it.

Ask your optometrist, gentlemen. It is the cheapest answer available.
