The lesion will be at the opposite of the absent vision of the eye which is the left eye.

A lesion of the right optic nerve causes a total loss of vision in the right eye. the lesion would be of the left optic nerve is the vision were to be reversed
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.
Sharpness of vision is also called visual acuity.-Visual acuity is determined by the ability to see visual details (in normal light).
Visual snow is a rare condition that causes people to see static or flashes of light in their field of vision. It typically does not cause blindness, and most people with visual snow retain normal vision. However, in some cases, visual snow may interfere with visual tasks and quality of life, requiring management by an eye care professional.
It means seeing at 20 feet what a person with normal vision sees at 20 feet. A person who has 20/40 vision can see at 20 feet what the person with normal vision sees at 40 feet, etc. Some people have better than 20/20 vision.
Normal eyesight is typically defined as having 20/20 vision, which means a person can see at 20 feet what a person with normal vision can see at 20 feet. Eyesight can be measured using a visual acuity test, where a person reads letters on a chart from a specific distance.
If there is normal vision in both eye for the right half visual field but there is absence of vision in both eyes for left half of the visual field, then the lesion is in the left eye. Since the vision for right eye is clear, the lesion is in the left.
Normal vision in both eyes results in the right half of the visual field being dominant. The absence of vision in both eyes results in the left half of the visual field being dominant.
Usually a Snellen's Chart is used to assess vision.
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.
Sharpness of vision is also called visual acuity.-Visual acuity is determined by the ability to see visual details (in normal light).
When someone is decribed as having twenty-twenty (or more correctly 20/20) vision it simply implies that they have "normal" visual acuity or "sharpness" of vision. See "Visual acuity" in Wikipedia for a full explanation of the derivation of the term.
audio If vision is to visual then hearing is to sound or audio.
Having 24-24 vision means that a person can see clearly at 24 feet what a person with normal vision (20-20 vision) can see at the same distance. This is often used to describe individuals who have exceptionally sharp vision, surpassing the standard visual acuity. In essence, it indicates superior visual clarity and detail recognition.
A carefully and individually tailored program of vision therapy should result in a gradual improvement in whatever complex visual function is being addressed.
5/50 vision refers to a visual acuity measurement where a person can see at 5 feet what a person with normal vision can see at 50 feet. This indicates significantly reduced vision, typically classified as severe visual impairment. Such an individual may have difficulty seeing objects clearly at a distance, which can impact daily activities. This level of vision often requires corrective lenses or other visual aids to help improve sight.
Normal eye vision is typically defined as 20/20 vision, which means a person can see at 20 feet what a person with normal vision can see at 20 feet. This can be measured through a visual acuity test, where a person reads letters on a chart from a specific distance. Other assessments may include a refraction test to determine the need for corrective lenses, and a visual field test to check peripheral vision. Regular eye exams are important to monitor and maintain good eye health.
