How do doctors know if your blind?

How is blindness diagnosed? A thorough eye exam by an optometrist will help determine the cause of your blindness or partial loss of vision. Your eye doctor will administer a series of tests that measure: the clarity of your vision.

Can you randomly go blind?

Any damage to your retina, such as a detached retina or artery occlusion, is a possible cause of sudden blindness. A detached retina can cause total loss of vision in the affected eye, or it may only result in partial vision loss, making it seem as if a curtain is blocking part of your vision.

What Colour do you see when your blind?

Instead of seeing green and red as distinct colors, the person sees them as being very similar, thus the resulting color confusion and other frustrations. Color blindness is caused by a change or reduction of sensitivity of one or more of the light-sensitive cone cells in the eye.

How can you tell if a person is blind?

Many blind people can tell when a person is pointing or waving their hands or even looking at their phones by simple things like airflow and acoustics in the room. They do not hear better or have superhuman senses they just pay closer attention to the senses they have.

How do blind people perceive the world?

The blind use other senses and echolocation to perceive the world. Blindness is used to describe a wide range of visual impairments, though people often assume the blind experience complete darkness. Blind people perceive the world by using other senses, and even master the technique of echolocation for sight.

What are some things that help the blind?

Try a gift that engages other senses. Many blind people enjoy music and audio books. You can also try things like a braille label maker or a braille watch (assuming the blind person doesn’t already have them). You can also offer food, such as a fruit basket or chocolate, if you know their tastes.

What do completely blind people ‘see’?

Legally Blind: A person may be able to see large objects and people, but they are out of focus. A legally blind person may see colors or see in focus at a certain distance (e.g., be able to count fingers in front of the face). In other cases, color acuity may be lost or all vision is hazy.
