Final answer:
The ozone layer in the lower part of the stratosphere protects us from getting melanornia and eye problems.
Step-by-step explanation:
In the lower part of the stratosphere, a thin layer of gas called ozone protects us from getting melanornia and eye problems. Ozone absorbs and filters out most of the sun's harmful ultraviolet (UV) radiation, preventing it from reaching the Earth's surface. This protective layer of ozone is known as the ozone layer.
