Although I havent stopped wearing one if I'm the inly one on top deck I remove it.

Exemption isn't based on condition, just the ability to wear one without significant distress or risk.

Basically if you can wear one, you're not exempt - but the law still allows for you to remove it afterwards if it will cause you harm or distress.
