31M, optometrist noticed corneal haze during eye exam

Posted yesterday but did not include enough details so it was removed, sorry mods. Reposting again and providing more details as per the subreddit rules.

31 year old white male. Occasional drinker (3-5 drinks a week). Non smoker. Only notable medical history is intermittent dysphagia for the last 5 years. Doctors have ruled out MS, and given my age, seem to think it is anxiety induced. I only mention this because Dr. Google brings up something called Sjogrens, which apparently can cause dysphagia and corneal haze.

In terms of eye health, I have always slept with my eyes slightly open, but have never dealt with any major issues as a result of this.

I wear glasses most of the day, and my work has me staring at a screen anywhere from 10-12 hours a day. Occasionally wear soft contacts, anywhere from an hour to two hours in a day.

Saw an optometrist for an annual eye check up recently. He noticed corneal haze and referred me to an ophthalmologist. Didn’t seem super concerned but also get the sense he was trying to not freak me out. Unfortunately, couldn’t get an appointment until next month. My last exam was a year ago and the previous optometrist didn’t mention this.

I haven’t noticed anything particularly different with my eyes since my last check up. However, my prescription did slightly change.

2022 OD (Sphere +0.25, Cyl -3.5, Axis 003) OS (Sphere +0.50, Cyl -3.75, Axis 001)

2023 OD (Sphere Plano, Cyl -3.75, Axis 005) OS (Sphere Plano, Cyl -3.75, Axis 001)

Completely understand that no one can diagnose me, just hoping to get some more information in laymen terms. Is this pretty uncommon in my age group? Could this type of corneal haze be caused by sleeping with your eyes open?
