Light is crucial for our vision. We see objects around us when light bounces off them and enters our eyes. But sometimes, light can be the cause of vision problems when it causes halos or glare.
Halos are bright circles that appear to surround a source of light, such as oncoming car headlights. Glare is light that enters your eye but doesn't help you see better. Rather, it interferes with your vision.
Glare can be:

Amblyopia: Also known as "lazy eye," amblyopia is a condition that starts in childhood in which vision has not developed properly in one eye or the other. If amblyopia is left untreated, a child's vision will not develop correctly, and as the brain matures, one eye will remain with poor vision.
Aqueous humor: The clear, watery fluid between the lens and the cornea.
Astigmatism: A condition in which blurred vision is caused by the cornea being shaped more like a football than spherical like a basketball. Astigmatism may be compensated for through eyeglasses or contacts, or it can be corrected through refractive surgery.
Beta-blocker: A medication used in the treatment of glaucoma, beta-blocker eye drops help reduce the pressure within the eye by reducing the production of aqueous humor.
Carbonic anhydrase inhibitor: A type of medication used to treat glaucoma. Carbonic anhydrase inhibitors work by reducing the production of aqueous humor, thereby reducing pressure inside the eye.
Choroid: The layer of blood vessels between the retina and the sclera.
Choroiditis: A form of uveitis that causes an inflammation of the layer beneath the retina.
Conjunctiva: A thin layer of tissue that lines the inside of the eyelids as well as the outer surfaces of the sclera.
