My eyes are foggy. What's going on?

A fogging of the eye is a clouding that indicates problems with refractive media such as cornea, lens, or vitreous opacity. Most sudden manifestations are associated with corneal edema. Common causes include corneal trauma, corneal abrasions, keratitis, corneal foreign bodies, or corneal edema caused by glaucoma attacks, and corneal clouding after keratitis recovers. Some young patients wear contact lenses after wearing, if not good care or wear too long, overnight wear without rest is also easy to cause corneal edema, the patient will present fog. If the disease is slow, it may be due to cataract or corneal degeneration, it is recommended to go to a regular hospital for examination in time.
