Oh, gosh, as a fellow person w eye problems I can sympathize.

Failure to contract properly used to cause me a lot of problems in my
school years when I was in a class that used projectors or scopes, and
clay paper in books or articles was difficult but luckily a retinal
specialist I saw then got me using colored sheets of plastic over such
papers.  They used to be available then cheaply from stationary stores
or photography stores but I don't know about now. It also turned out
that I was over corrected.  I don't know about you but I have been very
myopic for many years so it is a choice of having things a little fuzzy
but larger in size or sharper but very small in my correction.  I do
better with fuzzier and some guessing because over-correction  or too
small a size puts me to sleep.

With recent damage (from glaucoma and vitreous tears) I was having
trouble with my iBook and falling asleep at it about a half dozen times
a day, but we have found that the MacBook screen is easier for me so I
now have that.  (Bad eyes get expensive...)  Computer screens have
really improved.  I used to have a special UV filter I had to hang over
them but no longer need to do so.

If you wear glasses has your correction itself been looked at by a
different ophthalmologist?  Have mechanical means to reduce glare (such
as filters over papers with high clay content), and even using
sunglasses with computer screens if needed, been tried?

Eyes do dilate with attraction, but it is possible that you could be
allergic to the ferrets, their litter, something they have rolled in,
pollen still trapped in their fur from a past pollen season (like
ragweed season just past), something in their shampoo, something in
their food or treats, etc. or sadly even to the ferrets themselves. Has
any allergy eye med like Patanol been tried to see if that helps?

Best of luck to you.  You can contact places like Lighthouse and
various other eye disease/sight loss groups to find out who the best
specialists are in your area.  If your university has a med school
there will likely be very good ones there.
