Twitching of your eyes is common especially in the cases of consumption of too much coffee or tea. Or if you read or did close work for a long time and wash your eyes. Or it could be due to lack of sleep or eye strain. I wouldn't get too concerned about it.
Another thing to consider would be from seasonal allergies which cause the eyes to be extremely dry. Apply Refresh eye drops or lubricant to restore moisture. Rest your eyes esp after reading or computer work before washing your face. Avoid prolonged exposure to computer work. Take frequent breaks to rest your eyes. Avoid eyestrain and Stress. Try to get enough rest and sleep. Moreover avoid drinking too much stimulants such as coffee and tea.
Another home remedy is to apply warm tea bags over eyes. This will also prevent you from developing wrinkles ;dark circles and puffiness around the eyes. Also the application of cold compress over the eyes would also help. to soothe the irritation.
As much as possible try to use sunshades to avoid dust. Sometimes, it's caused by a dislodged eyelash or some dirt. A good eye wash with Tearisol or Murine will help or plain warm clean water. Avoid rubbing your eyes to further cause eye irritation. Avoid wearing eye contacts until the symptoms clear; if you wear them. Avoid using any eye cosmetics for awhile. A word of caution; never share any eye cosmetics esp eye brush.
I had the very same eye problems. My eyes felt very gritty, sandy, painful and dry, irritated.and ,itchy . They were constantly red, swollen and twitching. I was tested for MS ( Multiple Sclerosis), MG (Myasthenia Gravis),and LE (Lupus Erythematosus), Hypothyroidism , Scleroderma and Scleratosis.and Tumors. These were all eliminated as differential diagnoses. Eventually, I was diagnosed with Blepharospasm with Ptosis. But in my case, it was so severe that it resulted in my inability to open my eyes. I became visually impaired. Refusing Botox shots, eventually, i underwent eye surgeries.
However, I strongly suspect that your eye twitching is most likely caused by the earlier mentioned less severe causes. and not from some eye disease. So try to follow my helpful hints to relieve this disturbing condition. The main goal is to keep those eyes well lubricated ;moist.;free irritation ;inflammation.;allergens such as pollen, pet's dander, cigarette smoke, air pollution, dust, weeds, and infection.
