Hyperopia

(Farsightedness)

The eye's shape is compressed, causing the focal point of the lens to be offset.

The compressed shape of the eye causes the focal point of refracted light to be inset. The compressed shape of the eye causes the focal point of refracted light to be inset.

How it affects UI design

Hyperopia can cause or exaggerate chromatic aberration. In some cases, corrective lenses can be the cause of exaggerated aberration. Be sensitive to juxtaposing highly saturated reds and blues, as they will create a "vibration" appearance called chromostereopsis. This can be unpleasant and causes text legibility issues.

Users may need to adjust text size in the interface for better legibility.
