Vision impairment can mean a wide range of things. What we want to know is how far away someone can see, how wide their field of vision is, and what detail they see. We also need to know how the environment affects someone’s vision. Things like can your guest see black on white or bright colours better, how does the sun and reflection from the snow, or shade, affect their vision.
We use this information to establish the clothing we need to wear and the best goggles/glasses for your guest. It also helps in establishing the best way to guide someone, and also how to present information.
