    Could this be cataracts?

    I have noticed a halo when i look into lights… like a slight glare. I am only middle-aged (40) so I don't think it's likely for me to be having serious eye problems at this stage yet… is this a sign of cataracts?

    It is possible that the halo you can see is caused by early cataract formation; however, there are several other possible causes, including refractive error (long or short sight, etc), raised intra-ocular pressure and various corneal conditions.
    Find a reputable optometrist and make an appointment for an eye exam.

    Generally halos are due to your cornea ,or the window at the front of the eye has edema.Cataracts ca also be the cause but less likely,a more serious cause is angle closure glaucoma so should be seen asap.Drugs such as digitalis and chloroquine can have the same effect

    Typically halos around lights are due to a corneal problem. If the halos are the same colour as the light then it’s probably cataracts or a refractive error. If the halos are coloured eg the colours of the rainbow, and the source light is white, then most likely it’s a corneal problem and could well be due to raised intraocular pressure. This could lead to glaucoma. Either way, it’s critical that you have an eye exam ASAP to rule out any serious conditions.
