Swelling, drooping of the eyelid, inflammation of the eyes, nerve issues, or weakness of the eye muscles could be the cause if one eye suddenly appears smaller than the other. It can occasionally occur momentarily due to an allergy, infection, fatigue, or inflammation, but if it is new or getting worse, it shouldn't be disregarded. If you also experience pain, redness, double vision, headaches, or changes in your vision, please have an ophthalmologist examine your eyes. Early assessment aids in determining the precise cause and appropriate course of treatment.

If the viral infection affects the eye or results in irritation and inflammation, it may produce redness and minor eye pain. Avoid rubbing your eyes or applying sporadic eye drops by yourself. Wash your hands frequently, keep your eyes clean, and stay away from bright light if it makes you uncomfortable. See an eye doctor right away if you get blurred vision, swelling, wetness, or increasing pain since chicken pox can occasionally harm the cornea or deeper areas of the eye.

Stress, worry, sleep deprivation, fatigue, excessive screen or mobile use, coffee, or eye strain can all cause trembling or twitching of the head and eyelids. Prolonged phone use might exacerbate the issue by leading to poor sleep and eye fatigue. Try cutting back on screen time, getting enough sleep, staying hydrated, and abstaining from excessive tea, coffee, and late-night smartphone use. You should contact a physician or neurologist for a complete evaluation if the shaking gets severe, spreads to other regions of your body, produces headaches or visual issues, or lasts for many days.
