You may be more interested in oils as eye drops because they provide more lubrication and longer lasting effects. One found that oil-water emulsions were more effective than solution-based eye drops. But there are no studies about the safety of homemade remedies using oils for dry eyes. Not all options have been tested on humans either.

Here’s what research on certain popular eye-drop ingredients say:

Castor oil: One pilot found that an eye emulsion of castor oil from Allergan effectively produced more stable tear film for at least four hours. Allergan has discontinued this product in the United States.

Coconut oil: There are no human trials involving this ingredient yet. One that used rabbits suggests virgin coconut oil is safe for human use, but it has no significant benefit compared to traditional eye drops and saline. In addition, coconut oils can be contaminated.

Omega-3 and omega-6: No human trials have been done for these. A 2008 cell suggests more research on its benefits for a topical application.

Chamomile tea: A 1990 concluded that a chamomile tea eye wash induces allergies and swelling. It’s best to avoid a tea-based eye wash due to potential contamination.

  • only use a fresh batch to avoid bacterial infections
  • use clean equipment that’s been recently washed in hot, soapy water
  • throw away any solution after 24 hours
