Usual dosage for mild dry eye patients or patients with occasional intolerance in the eyes is 1 drop 2-3 times a day.

However you can use Hye Light ^TM as often as you need it.

In case you are a chronic artificial tear user prefer Hye ^TM. For long-term and frequent use Hye ^TM proves to be much more economical because of lower dosage and of course it is much more effective than  Hye Light ^TM.
