It depends on the medical condition.
Temporal vision loss, often referred to as "temporal visual field loss," can occur due to damage to the optic nerve or pathways in the brain responsible for processing visual information from the nasal part of the retina. Conditions such as glaucoma, retinal detachment, or lesions in the brain (like those caused by tumors) can lead to this type of vision loss. It typically results in a loss of peripheral vision on the temporal side, affecting the ability to see objects on the sides. Early diagnosis and treatment are crucial to prevent further vision deterioration.
Hypoglycemia will occur, causing blurring of vision, headache, loss of consciousness, syncope, seizures, even death.
Vision and visual perception occur in the occipital lobe of the brain.

30 50 is considered mild vision loss, or near-normal vision.
Some of the conditions that occur more often among children with Down syndrome include: heart defects, vision problems and hearing loss.
When does a net loss occur
I RECENTLY WENT TO MY NEUROLOGIST CONCERNING PERIPHERAL VISION LOSS IN MY LEFT EYE FOR ABOUT AN HOUR. PRIOR TO THE VISION LOSS i HAD PAIN IN BOTH EYES. MY DOCTOR TOLD ME THAT IS WAS PROBABLY FROM A MIGRAINE EVENTHOUGH I NEVER GOT A MIGRAINE BEFORE OR AFTER THE VISION LOSS. SO THAT IS AT LEAST ONE REASON. I ALSO HAVE MULTIPLE SCLEROSIS WHICH IS AN AUTOIMMUNE DISEASE. I WAS DIAGNOSED WITH MS AFTER HAVING OPTIC NEURITIS. OPTIC NEURITIS IS AN INFLAMATION OF THE OPTIC NERVE. I ASSUMED THE VISION LOSS I RECENTLY HAD WAS DUE TO THE MS BUT MY DOCTOR DIDN'T THINK SO.
Ferrets are know to have poor eyesight and are very adaptable to vision loss. A vision impaired ferret may be easily startled and react by biting, so you need to approach them gently.
The first symptoms, a loss of night vision followed by a loss of peripheral vision, usually begin in early adolescence or young adulthood.
The density and location of the cataract determine the amount of vision affected.
