I seem to find it more difficult to see things in low light compared with other people. Am I imagining things?
It's not uncommon. In low light levels, your pupils become larger and this can emphasise any small underlying errors in focussing, causing a blurred effect.
Occasionally, more serious conditions might cause problems with night vision, so you should book an eye examination with an optician and tell them your symptoms. They will give your eyes a thorough health check and find out whether you might benefit from spectacles or need a change in prescription.
