Dry eyes can occur from involvement of any of the 3 layers of the tear film. The tear film has 3 layers- aqueous, lipid and mucin. The most frquent layer to be affected is the aqueous layer. It is seen due to increased evapouration of tears as can be seen with excessive hours in front of the laptop/computer/television or long hours of continous reading or writing. It can also be precipitated by excessive exposure to air conditioning or even very hot and humid climate. The treatment is in the form of tear supplements such as over the counter preservative free Refresh tears eye drops , 1 drop 4 times a day for about a month.If severe then lubricating eye ointment can also be used such as Lacrilube eye ointment, once at bedtime. Both of these eye medicines are available over the counter.
For seasonal allergic conjunctivitis, I would suggest that Pataday(olopatadine) eye drops, 1 drop twice a day can be used for 2 months. It is quite effective and helps to prevent recurrances.It is a prescription medicine. If you have not been examined by an eye doctor yet , then it is better to consult one, if the symptoms persist even after 1 month of regular use of the above suggested eye drops.
