6th Grade: Complete and submit work on Google Classroom
Yesterday we learned how the eye really works and how we really see. We examined diagrams of the eye and how it produces images. We traced the light from the cornea, lens, pupil AND distinguishing rod cells from cone cells. Sight depends on the eyes detecting light and forming images. It also depends on the brain making sense of the images, so that we know what we are seeing.
Today we will be learning about Vision problems.
I can explain how vision problems such as myopia and hyperopia can be corrected with lenses that help focus light on the retina.
Define myopia and hyperopia.
Explain how lenses correct vision problems.
