Dry eyes is a severe problem. In this condition, eyes could sting and feel burning & pain. Dry eyes could also lead to eye inflammation, corneal ulcer, cataract and other vision problems.

Eye drops are normally prescribed by the physician in this condition but in my opinion (which could be wrong as I am not a professional) this device would be proven more useful as it is sending the signal to the brain and eyes are producing tears naturally.

Nice hunt, @hafizullah & Good Luck.
