Answer:
1) Night blindness caused by nearsightedness, cataracts, or vitamin A deficiency is treatable. Corrective lenses, such as eyeglasses or contacts, can improve nearsighted vision both during the day and at night.
3) Corneal xerosis is characterized by a dry, hazy appearance of the cornea. It may start as superficial, punctate epithelial lesions. This stage quickly progresses to the stage of corneal melting or keratomalacia. Up to this stage, high-dose Vitamin A supplementation can result in the full preservation of vision.
4) A corneal ulcer is a small crater (ulcer) on the front part of the eye, usually resulting from infection. Bacteria, viruses, or fungi can cause a corneal ulcer. People who wear contact lenses are at higher risk for corneal ulcers because infectious agents may get trapped behind a lens.
