One of the most impactful things that you can do to stabilize vision and reduce digital eye dryness issues is use non-preserved rewetting eye drops formulated for evaporative issues (such as I-DROP MDG or Thealoz®). To be effective these drops should be used at least twice a day i.e. proactively!.
This is especially true for contact lens wearers as the ocular surface dries more quickly!
Warm compresses, prescription medications and Omega 3 supplements are also used to combat dryness – digital or not! See the Dry Eye BLOG posts
