If the focal point of light does not hit the fovea centralis, vision can become blurred or distorted. The fovea is responsible for sharp central vision, as it contains a high concentration of photoreceptor cells (cones) that detect fine details and color. When light is focused elsewhere on the retina, image clarity decreases, affecting overall visual acuity. Conditions such as refractive errors can lead to improper focal alignment, resulting in compromised vision.
The fovea centralis, also generally known as the fovea, is a part of the eye, located in the center of the macula region of the retina. It's important because it's the center of the eye's sharpest vision and the location of most color perception.
In an eye with 20/20 vision, the fovea is the focal point where the light coming through the lens converges.
Focal vision
focal length of the lens
The distance from a lens to the focal point is called the focal length.
Focal Point:The distance from the Lens to the Focal Point is called the Focal Point.
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.

The focal point of a circle is the center.
The distance from the center of a mirror to the focal point is called the focal length.
