What is spherical aberration?
Spherical aberration occurs when light rays refract at different angles as they
pass through the eye. Even after basic vision conditions like nearsightedness and
farsightedness have been corrected, it can remain and impact your quality of vision.
Spherical aberration's effects are less noticeable in daylight, but they can cause
objects to appear blurry or hazy in low-light situations, too.
