8. See halos around light
If your eyes have difficulty focusing light, then “halos” or rings may appear around sources of light, such as lamps/light bulbs in your home, car headlights or street lamps etc. Sometimes this can be easily corrected with a pair of glasses or contact lenses, however, it may also be a sign of the early stages of cataracts. Either way, it’s best to get a check up, as you may be in need of some glasses!
