Which type of glasses should not be worn when driving at night?
- A Half-moon
- B Varifocal
- C Bifocal
- D Tinted
Why this is the answer
If you're driving at night or in poor visibility, tinted lenses will make everything appear darker. This will make it more difficult for you to see in what are already difficult conditions.
Why the other answers don't fit
- A
- Half-moon — The shape of the frame is not the problem; how much light gets through is.
- B
- Varifocal — Varifocal lenses are clear and may be worn at night.
- C
- Bifocal — Bifocals are also clear; it is tint that cuts the light.
Where this comes from
- Driving: the essential skills — section 13
- The Highway Code — rule 94

Where this question comes from
The question, its options and the explanation are reproduced word for word from the DVSA revision question bank under licence. The licence requires them to appear unaltered, so we cannot reword them and neither can anyone else — that is why you will meet the same wording on other sites. Everything else on this page is written by Theory Hub: the explanation of why each wrong answer is wrong, the topic guide and the revision notes.
