Hello my dear Steemians,
Today I wanted to write for this contest that is running by @sahar78 , here is the link if you are also interested:
Eye is one of the important organs that give us a lot of information about our surrounding. Sometimes people are born without being able to see that makes a person handicap. When we are born majority of us are born with two healthy eyes and we are able to see everything, close and far. As any optical instrument our eye has a complex structure and also in order to be able functioning for a long time there is a protective shield, that is called “Cornea” and that is a shield that covers out pupil, iris and surface of eye.
As anything in our body needs care but also we need Vitamin and nutrients. For the important part of our eye for cornea we need Vitamin A, which is necessary products that keeps our eye sight being able to work properly. In some cases if there are not enough of Vitamin A, then cornea becomes dry and sometimes our glands for tears are not functioning and when we have any foreign body in eyes then eye is not able to wash it out with tears and people have a feeling of sand in eyes. Often those people will develop night blindness and without Vitamin A long term those problem can cause irreversible blindness.
Some people can get injuries and loose the eye sight either complete of some percent of it. While there are some diseases that can make your vision difficult such as Diabetes and using some medication like steroids. With the time we get older and there are age related changes that everyone will experience such as we can not see close very well, although it is still okay to see and recognise everything as well as reading on remote distance. That is often just happens once we are about 45 y.o. There is a way of help in such situation is reading glasses.
Couple of decades later, there are some degenerative changes and that is something that often difficult to fix. Another disease known like cataract is also happen when we are older and can affect our vision
I hope you also learnt something interesting today and I would like to invite @dave-hanny, @meriseptriyanti @djvijay for the contest.

Vitamins are very important for normal vision and for immune system reproduction. Nice write up

Yes, often we do not think about that until we suffer from lack of it :)
