Hello , my name is Dr.Dorina Gurabardhi. I understand your concern.
Some reasons that cause dryness on the eyes are:
-your air conditioner, heater, or other things around you could dry out your tear film.
-The natural aging process, especially menopause
-Side effects of certain drugs like antihistamines
Some advices that I can give to you are :
-Artificial tear drops and
ointments. This is the most common treatment.If you have chronic
dry eye, you need to use the drops even when your eyes feel fine, or they won’t stay wet enough.
-You can use
steroid eye drops, for
short periods, along with long-term measures.
-Adding fish oil or
omega-3 to your diet or can also help
Hope my answer was helpful, if you have any other questions I'll be glad to help, thanks!
