Dear optiboarders,
The last few weeks in my practice I had some customers with oblique cylinders (C-0.75 axis 135 and 45) which I prescribed the Hoyalux iD. Four of those customers really had problems adapting to the PAL. The following problem occured in all those 4 customers: when looking down they had the feeling the ground was more near then without the lenses; the world was spinning around when walking around. They had no problems just looking straight forward, but the problems occured when turning the head or walking. When we removed the cylinders from the lenses the problem was resolved.
Did anyone encounter this problem? Or does anybody know some research articles about oblique cylinders and progressive lenses?
I hope you guys can help me out.
Greetings,
Eelco
