I'm worried about dry eye syndrome.

Some time ago, my eyes started feeling dry and tired. I think it's because I often look at screens on monitors and phones for long periods. Artificial tears bought at the pharmacy provide temporary relief from dry eyes, but after some time, my eyes become dry and stiff again. I visited an ophthalmologist and was prescribed various eye drops, but if I use them consistently and on time, will my condition actually improve? From now on, I need to pay close attention to my eye health.
