The far point of a normal, relaxed eye is at infinity. True or false?

No

Not sure

Yes

The far point is the distance from the eye at which light from a point would be focused onto the retina when the eye is relaxed (unaccommodated). For a normal, emmetropic eye, parallel rays from objects at infinity are focused onto the retina without any effort, so the far point lies at infinity. That’s why distant objects can be seen clearly without accommodation. In other situations, like myopia, the far point is a finite distance in front of the eye, which is why distant objects blur unless corrected. So the statement is true.

It depends
