Usually halos are indicative of glaucoma. But At this age glaucoma is unlikely  ,unless you are using steroids drops for a longer time. There are many other conditions resposible. Hence i will suggest you to get your complete physical examination done.

Not necessarily it is due to glaucoma ...need to examine and do full retina check up..use lubricating eye drops optive 3-3 times a day in the meantime

Hello There are many eye conditions in which a patient reports haloes around light bulb Glaucoma is just one of them.

Coloured haloes seen as soon as you wake up and goes away with blinking.. and after that if you are perfectly fine.. mostly it is due to mucus in your eyes due to allergic conjunctivitis. Other reasons are glaucoma and cataract. Try using lubricant eyedrops and wash your eyes with cool water. Still if it persists seek an online consultation.
