Twitching can occur in any muscle in the body. There are many causes for that like stress, caffeine, eye strain
, allergies and nutritional imbalance.
Your twitching of eye muscle might be due to electrolyte imbalance
mostly happens due to dehydration
. Some electrolytes are need for proper muscle function so have a proper hydration with ORS solutions, drink more water, and do some eye exercises before sleeping. Take some hot steam inhalation for nasal allergies.
