Try natural balance trears works good for me after having eye surgery.

This is what my eye doctor said I have.
Posterior Vitreous Detachment (PVD) is a natural change that occurs during adulthood, when the vitreous gel that fills the eye separates from the retina, the light-sensing nerve layer at the back of the eye.

Causes really dry eyes.
Thats why he said to get Systane Balance for eyes cause it has what we need for our eyes not getting.

Systane, Visine and Lumify all work well for me.

I bathe my eyes every morning with simple household salt dissolved in hot water, steep a white flannel in the water then hold against your eyes DONT WIPE
This stops the itch and soreness. Hope it works for you.

Systane Balance eyes drops. My eye doctor told me to get this. He said as we get older that our eyes do not produce as much oil as they should. These drops do help. Walmart has them.
