- Summary
Pedagogical animation of the hyperopic eye. Hyperopia or farsightedness is a condition where the eye is too short in relation to its refractive power. The light rays intersect behind the retina.
The corrective lens modifies the focal to shift the point of intersection to the surface of the retina. We also show that correction moves the "near point" closer to the eye.
You can click and drag the object to move it along the optic axis.
Diagrams are not drawn to scale.
- Learning objectives
