Elephants have very good hearing and sense of smell, but poor eye-sight. Their normal hearing range depends on the volume of sound.
The normal eye vision range for individuals without visual impairments is typically 20/20. This means that a person can see at 20 feet what a person with normal vision can see at 20 feet.
The normal eye vision can detect a stimuli of over 120 degrees range vertically. It can also detect 160 degrees range horizontally.
What is the normal range?
The typical range of eye vision for humans is between 20/20 and 20/200. 20/20 vision is considered normal, while 20/200 vision is considered legally blind.
The normal range is
Its like a normal eye
Normal range is 6.0-7.0.

Far point- it is the range till where our eyes can see and in a normal human being it is infinity.Near point- it is the nearest possible distance from our eye till which we can see an object clearly. it is 25 cm in human.

The normal relationship between the refractive power of the eye and its shape is crucial for proper vision. The eye's refractive power, primarily determined by the cornea and the lens, should match the length of the eyeball; this ensures that light rays are focused directly on the retina. A perfectly spherical shape allows for optimal curvature, facilitating accurate focusing. If the eye is too long or too short, it can lead to refractive errors such as myopia or hyperopia, respectively, causing blurred vision.
