What Vitamin Deficiency leads to blinking of eyes?

[Ayuryogashram]

Hi friends, Recently i started to blink my eyes frequently. I don't know the real reason behind it.

May be it is due to some of the vitamin deficiency and don't know what it is. Can anyone help me in clearing my issue so that I can control or stop blinking every time.

Also let me know whether i need to go to eye hospital for a general checkup.
