It looks like you must be allergic to something in environment , if so, both eyes should be affected usually.
Because of allergy there is periocular swelling which is minimal during day and as day passes u are more exposed and hence edema deteriorates.
Ocular allergy leads to tear film diaturbances which causes dry eyes and hence frequent blinking and may be twitching sometimes.
Also notice any drooping of eyelid once there is no swelling in lid.
Next Steps
start using antihistamine eye drops and frequent lubrication for atleast 4 wks.
Health Tips
Consult neurologist, if similar twitching or weakness or any sensation in any other body part.
