That is not true; please be careful to do research before posting so you don't spread misinformation. If a light source is diffuse/omnidirectional, then it will be blurrier the farther it is from the distance your eye is focusing on. Only if the light is a ray (a collimated beam with very little spread and very small diameter), such as the ray produced by a laser, then it will be in focus regardless of the distance at which it is produced.
