True blindness may be caused by trauma to the eye, severe conjuntivitis due to IBR (infectious bovine rhinotracheitis) or pink eye or other infections, leptospirosis, lead poisoning, selenium toxicity, fungal infections, vitamin A deficiencies, rabies, vitamin B12 deficiency, neoplasia of the orbit or conjunctiva, cataracts, congenital malformations, etc.
Blindness is fairly uncommon in cattle, but it can occur for several reasons. Blind cattle may be seen circling, knocking into objects and have no menace response ( they won’t blink when a hand is waved in front of their eye).
Common diseases that cause blindness are onchocerciasis, syphilis, diabetes, glaucoma, trachoma. Many other less common diseases may cause blindness.
Night blindness, xerophthalmia or dry eyes, blindness, dry eyes, and other inflammatory diseases and conditions.
Depends on what diseases the cattle had and whether they were transmissible to humans or not.

Yes. Cattle that consume this plant can develop paresis, loss of coordination, blindness and even death.
diseases caused by D.N.A are also called genetic diseases and include hay fever asthma and colour blindness

Yes, night blindness can be genetic. It is often associated with inherited conditions such as retinitis pigmentosa and congenital stationary night blindness, which affect the retina's ability to function in low light conditions. Genetic mutations in specific genes can lead to these conditions, resulting in difficulty seeing at night or in dimly lit environments. However, night blindness can also be caused by non-genetic factors, such as vitamin A deficiency or certain eye diseases.
