7. Medication side effects: Some medications, such as stimulants or antipsychotics, can cause muscle twitching as a side effect, including eyelid tremors. 8. Allergies: Allergic reactions can cause eye irritation and inflammation, which can trigger eyelid twitching. What to Do to Prevent Eyelid Tremors? While eyelid tremors are usually harmless and temporary, there are some steps you can take to prevent or alleviate these involuntary movements: 1. Get enough rest: Make sure to get an adequate amount of sleep each night to prevent fatigue-related eyelid tremors. 2. Manage stress: Practice stress-relief techniques, such as deep breathing, meditation, or yoga, to reduce muscle tension and prevent eyelid tremors.
