Why is it easier to see items at a far distance than close-up?
If a person can see things far away better than close up, this is called far sightedness.

If the image focuses in front of or behind a certain point in the eye, it will cause far sightedness or near sightedness.
What is the antonym of myopic?
The opposite to myopic/myopia is HYPEROPIC/HYPEROPIA. Myopia is also known as short sightedness or near sightedness. Hyperopia is also known as long sightedness or far sightedness. A myopic eye focuses the image before it reaches the retina at the back of the eye. This is because the eye is too strong. A myopic eye will find it easier to focus on a close up object rather than a far away object. A myopic eye needs to be corrected with a minus/negative powered prescription lens (-). A hyperopic eye focuses the image after/behind the retina as a hyperopic eye is too weak. A hyperopic eye will have problems focusing on close up objects and in some cases it won't be able to focus at any distance. A hyperopic eye will be corrected with a plus/positive powered prescription lens (+).
