Dry eye is a condition to manage rather than cure.

It differs by cause. Where screen use or the environment is the main factor, there are cases of becoming comfortable relatively early once those are adjusted. Where menopausal hormonal change or an autoimmune condition is the background, it must be managed over a long period.

The measures by which we follow the course are how many times you put in artificial tears and the point in the day when the eyes become gritty. Change comes in the form of discomfort that lasted all day becoming confined to the afternoon.

It is also affected by the seasons. Many people worsen in the dry winter and in summer when air conditioning is used.
