First, we have to do the “Arrrrstigmatism Test."
Step 1: Astigmatism Test + Materials
You see, the lens ‘n your eye is similar to the lens in me telescope. When light hits the cornea, or the lens of your eye, it is focused onto one single point in the retina, where the image is detected and communicated to the brain. However, in people with astigmatism, the light is focused by the lens onto more than one point in the retina, causing t’ blurry effect. Now, let’s try it out with an eye model. I gots it when I searched for treasures in the Caribbean. Just kiddin’.
You will need the following materials:
PASCO Human Eye Model OS-8477
+62 mm lens
-128 mm lens
