Twitching or cramps in the eyelids is called Blepharospasm and is usually transitory. If this condition persists, the Homeopathic remedy Codelia is used - probably in a 30C or 1M potency. If the muscles of the eye are affected as well, then you will need Agaricus in similar potencies. Talk to your nearest Homeopath about the remedies and they can supply all you need. If yu have access to dried (or fresh) Bilberries, eating a handful of these will also ease twitching and irritation in the eyes and lids.
