eyesight problems in dementia 2

I wonder why it is that Doctors don't understand the distress things like floaters in the eye cause to people living with dementia.

I now struggle to read unless I close one eye so that I don't see objects floating around in my other eye, and this is alarming at times 

Yet some doctors say everyone has them, and you just ignore them, but living with illness it's impossible to do

These things can be alarming at times, especially if you think you can see something like a spider on your eyeball.

These weird shapes can be very distressing when they  cross your eyesight.
