In brief: Viruses
Pink eye in general means that you have a severe virus that causes significant itchiness.
Most people however with a crusting, eye redness, lid swelling have an unstable tear film from blepharitis. See Eyedoc2020.blogspot.com "lid hygiene" on how to use warm compresses & diluted tea tree oil on closed lashes to help & list of other csuses

In brief: Several causes:
Pink eye, also called conjunctivitis, can be caused by a virus, a bacteria, or an allergy.
Each one presents slightly differently, so it is important to get seen and diagnosed properly to get the proper treatment. A few serious problems can also cause a red eye. If you have pain or decreased vision, be seen immediately. Blepharitis is infection of the eye lid and lashes, not the conjunctiva.

Most often "pink eye" refers to contagious viral conjunctivitis or an infection of the lining of the outer eyeball and lids.
The most common species are adenovirus that also are associated with common colds and upper respiratory infections.
