Welcome to HCM.. Thanks for the query..
Is the eye getting totally closed or just twitching?
It could be an essential blepharospasm
where you have an involuntary closure of eyes..It can range in severity from fine twitches to total closure of the eye affecting the vision...
Depending on the severity and symptoms botox
injections can be given to relieve the spasm..
Or twitchings can be because of stress
also.. because of excessive near work or computer use.. Take some simple measures like voluntary blinking of eyes, regular breaks in between work, using artificial tear drops etc.,
Hope this information helps you.. Take care...
