Our eyes are one of the most important organs we have. Our eyes
allows us to see and understand the things around. They are also a way the
brain collects raw material to understand what we see to what we know, so it is
our responsible to keep them in a healthy condition.
Hence, the invention of photochromic lenses. There are
lenses that can darken to the intensity of UV radiation we are exposed to. I think
it is a great combination of two object; which are sunglasses and normal
spectacles. This also because it benefits the human body directly.
Another object is the toilet hand basin. I think this object
is a great way to save water. It is important for us to save water not only
because it cost a lot but because there are other countries that don’t have
access to clean water or in the worst case don’t even have enough water for the
country; for example south America has access 27.6 % of the water in the world percentage
whereas Asia which consist of many countries has only 30.6 % of the water in
the world. Therefore, if we can reduce the amount of water used, why not we do
so? I meant we do live of water, one way or another.
