I have Lamellar Ichthyosis and have significant sight issues due to corneal scarring. For the most part this is because my eye lids don't close properly and i don't blink because of it, which essentially means my eyes don't clean themselves and dry out easily. To help I use lacrilube at night and natural tears during the day.
The best way to discribe my vision is that its like looking through a pair of glasses that has been scratched significantly. I can see okay through the scratches, but when strong light sources hit them it flares and can at times be quite blinding. It would also be fair to say that I can not see as far or as accurately as most can, and due to this I no longer drive.
It would be best to wait to see what the doctor says, and go from there, no point stressing until you know what the true situation is.
