In cases of total blindness, where there is complete loss of vision due to conditions such as optic nerve damage or retinal degeneration, it may be challenging to fully restore vision. However, advances in medical technology such as retinal implants, gene therapy, and stem cell treatments show promise in potentially restoring some level of vision in the future. It is important to consult with medical professionals and specialists in the field of ophthalmology to explore available options and discuss individualized treatment plans.
The blind spot is the point is a person or animals vision which they cannot see without turning their heads. For predators the blind spot is behind them, but they have excellent front vision. For prey eyes tend to be on the side of the face rather than at the front in the center, this gives prey a much wider area of vision, but makes focusing on objects directly in front of them or behind them more difficult, these are the preys blind spots. In a car, the blind spot is the area you cannot see by using any of your mirrors, it can be seen by turning and looking over your shoulder and is the area between your immediate left and right upto about 5 metres back.
We have blind spots because part of the retina in our eye do not have light sensitive cells. Fortunately, we are not aware of our blind spots because the blind spots of our two eyes do not coincide.

At the small spot in each eye where the optic nerve exits the eye, they are no light receptors and therefore no vision. The blind spots are to the outer sides of the field of vision and therefore less critical than if they were close to the center. Also, the blind spot in each eye is compensated for by the other eye for those who have two intact eyes.
Legal blindness definitions vary but most commonly, if someone is registered legally blind they have visual acuity of 20/200 (6/60) or less in the better eye with best correction possible. Someone with average visual acuity may also be registered legally blind if ther visual field is less than 20 degress (around 180 degrees is normal) ----------------------------------------------------------------------------- When one's eyesight is so bad that it cannot be corrected back to at least 20/40 vision, but can still see light and shapes, then one is considered legally blind. ------------------------------------------------------------------------------ Some people have vision at all and they are of cause blind however, other people may always have had some vision or started out with vision that is now starting. There has to be some objective measure for these people which distinguishes them form people with just poor vision and allows them access to extra services to help them if they need it. The usual standard is that anyone with vision worse than 0/200 that cannot be improved with corrective lenses is considered legally blind. In addition, people with a visual field of less than 20 degrees diameter (10 degrees radius) are also considered legally blind.
The blind spot is also called the optic nerve head. It is located on the retina, about 15 degrees horizontal from center vision.
No one knows as no one has come back from the dead that has been blind to say what has happened after death. //I have heard a blind man declare that in a NDE (near death experience) he had sight. For the first time he was able to actually see, once he recovered his sight was gone again. It was only during the time he spent in the 'afterlife' that he had vision.//
You might be able to get your account back after being banned from AirG but it is totally up to the operators. You can try writing a letter or complaning to the account representatives, but there is no simple solution for getting your account back.
yes it can
people go back on your questions and think about it she is not blind ok put your head on
how could you be legally blind and be a quarter back? Jim Plunket's paretns were legally blind though.
the eyes is located a Little on the sides instead of front. A horse have a blind spot but it can kick real if you are there its in back of it. and I believe on the nose. so it cant see your hand if you have it strait in front of the head (centimeters).
