Question

Snow blindness is caused due to
A) Ozone hole
B) Nuclear winter
C) Acid rain
D) Greenhouse effect

Answer 1

Hint: Photokeratitis is brought about by characteristic or counterfeit overexposure to UV light. The "photograph" portion of the word signifies "light" and keratitis is an irritation of your cornea.

Complete Solution :
Snow blindness is the condition of loss of vision due to overexposure of UV light. When the layer of ozone gets depleted, a large amount of UV radiation starts reaching to the earth's atmosphere and an increased dose of UV radiation causes diseases.
Atomic winter or nuclear winter is a serious and drawn out worldwide climatic cooling impact estimated to happen after boundless firestorms following an atomic war. The theory depends on the way that such flames can infuse ash into the stratosphere, where it can hinder some immediate daylight from arriving at the outside of the Earth.
Since the mid 1980s, the world has realized that a huge atomic war could cause serious worldwide ecological impacts, including emotional cooling of surface temperatures, decreases in precipitation, and expanded bright radiation.
Acid rain has appeared to impact woodlands, freshwaters, and soils, executing bug and amphibian living things, making paint strips, consumption of steel structures, for example, extensions, and enduring of stone structures and sculptures just as having impacts on human wellbeing. So, this is not a correct answer.
The greenhouse effect is brought about by the air gathering of gases, for example, carbon dioxide and methane, which contain a portion of the warmth discharged from Earth's surface. The environment permits the vast majority of the noticeable light from the Sun to go through and arrive at Earth's surface. This is also not a correct answer.

So, the correct answer is option (A), Ozone hole.

Note:
Snow blindness ordinarily disappears on its own once your corneas recover. Indications will in general progress progressively longer than a day or two, as per the American Academy of Ophthalmology.
A specialist can affirm whether you have photokeratitis by looking at your eyes for UV harm. There's very little your PCP can do to treat photokeratitis. Resting your eyes from UV light is the most ideal approach to support mending.
