There are a number of different medications that can cause eye twitching during pregnancy and it's important to check with your doctor to find out if any of your medicines are contributing to the problem.

If you have allergies, this is another cause of eyelid twitching during pregnancy, especially because allergies may be made worse just by being pregnant.

Finally, your eyeglass or contact lens prescription could change dramatically during pregnancy, especially if you have diabetes or gestational diabetes. If this happens, you could develop eye strain from not being able to focus on objects properly and this eye strain can thus lead to eye twitching. So, it's important to also have your eyeglass prescription checked during your pregnancy to determine if it needs to be changed.
