This patent application discloses a method of manufacturing eye drops that can be used to ameliorate or cure eye conditions such as cataracts, presbyopia, glaucoma, astigmatism, dry eye as well as for generic eye care uses. The sole active ingredient of said eye drops is citric acid—its aqueous solution around 0.9% by weight, which can be adjusted to either higher or lower levels of concentration according to clinical needs. Citric acid can be sourced either from industrial products or from natural fruits such as lemons and pineapples.
