Keratomalacia is a disorder of the eye. More specifically it is a degeneration of the cornea from vitamin A deficiency. It is with associated dryness that can lead to corneal thinning and perforation.
You get the symptoms and signs of vitamin A deficiency. Those are night blindness, Bitot's spots, keratomalacia and corneal ulcers and blindness. Your diet is usually deficient in vitamin D, unless you eat fish, specially fish liver. You get the vitamin D in presence of sunlight. Sub-clinical deficiency of vitamin D is very common, probably.
Insectivorous plants (flycatcher, sundew and slug catcher, to name only three) can grow in nutrient (mineral) deficient soils because they can catch insects and absorb the insect's nutrients.

Air, moisture and nutrient content are ways to compare compost and soil. Soil can be nutrient- and water-deficient in the case of sand and nutrient- and water-retentive in terms of clay and loam. Dark-colored, fresh-smelling, nutrient-rich compost may be added to correct air, moisture and nutrient deficiencies or excesses through amending, fertilizing or mulching actions.
