I just got my prism glasses on Friday and was told to start wearing them slowly, starting with 2 hours a day. I have prism sunglasses and prism reading glasses. The first 1/2 hour seemed fine and I had them on for about 1 1/2 hours the first day. The second day I was a passenger in a car and my vision doubled and was blurry. Is this normal or does it mean I had them on too long. I can't get over how distorted things sometimes look, it like looking in those funky mirrors at the fair. Anyone have different experiences.

I was told to wear them full time right from the beginning. Distorted vision etc. will occur because you are retraining the brain to see in a different way. I think it took me a good three or four weeks to really notice a benefit in terms of reading and feeling better. Some people adapt right away.
You may want to revisit the idea of wearing them for short periods of time to start. your brain will be required to jump back and forth and I wonder if that is a good thing! I think I would try 100%. Studies on prisms in glasses show that people (even without a brain injury) have a very quick adaptation time.
Perservere. I think it should make a difference!!
Hope so.

Perhaps your vision is also difficult as a passenger in a moving vehicle? I have been told that if you have vision difficulties (binocular vision, for me), tracking moving objects while riding in a car would elicit motion sickness and headaches.

For me, the prism glasses at 100% took four weeks to notice a difference, and even now, I am struggling. It is better, but slow progress.

Don't hesitate to contact your neuro-opthalmologist! They can provide advice based on your feedback.

Good luck!
