What i want to ask is,
When we get problem in our Eyesight, we get them checked up and set spectacles. This is also very much true that both the eyes have different eyesight and there fore different lenses are used to clear the problem.
So i just had a thought that, if the two eyes are different, then why do tears come from both of them and not from just one.

Tears come from the tear ducts just inside the bottom eyelid. They both produce tears but can be stimulated to do so individually. When you are crying both eyes water because that is the instruction given to the tear ducts by your brain. If you apply local stimulus to just one eye to make it water, only that one will water because it is a reflex response.
Stigmatism is a condition where the focus of your eyes are different from each other and require glasses to compensate. The problem comes from either development defects or strain on the eyes in different proportion to each other.

Tears are caused by tear ducts not the eyes. When your emotions are high the tear ducts overact and give your eyes more water than they need.

Its kinda like turning on two spigots at the same time and having hot and cold water coming out of the same spout.

Funny you should ask, my tears generally come from one eye.
I don't see why there should be any connection between correcting faulty vision and crying.

Because lacrymal glands are present in both the eyes.they do their work properly.
