Do blind people have faster reflexes?

Nope. Reflexes are completely independent of sight. They are neurological reactions to stimuli (predominantly touch).

Do blind people have pupillary light reflex?

If a person is blind because of retinal damage, they will no the generating visual signals to the optic nerve, and again, no retinal response. If the blindness is caused by damage to the optic nerve, even though the eye itself is intact, there will be no pupillary response.

How is legally blind different from blind?

Legally blind means a person has a corrected vision of 20/200 in their best-seeing eye. If visual aids such as glasses can correct a person’s vision to 20/20, they are not considered legally blind. Totally blind refers to a complete loss of sight.

Is a blind person just doing more with the same information than a sighted person does?

A new study from the University of Montreal found that blind people have no keener sense of smell than the sighted. Vision loss simply makes blind people pay more attention to how they perceive smells, the researchers said.

What is the fastest human reaction time?

around 0.15 s
The fastest possible conscious human reactions are around 0.15 s, but most are around 0.2 s. Unconscious, or reflex, actions are much faster, around 0.08 s because the signal doesn’t have to go via the brain.

Do blind people have light sensitivity?

The vast majority of legally blind people have some degree of vision. People with sight loss commonly experience photophobia, also known as light sensitivity. Sunglasses can help people with photophobia protect the eyes from bright lights that may cause discomfort or further vision loss.

Do blind people have no pupil?

Broadly speaking, like anything else having to do with blind people, it all depends on why they’re blind in the first place. If they were on safari and captured by Natives who poked his eyeballs with red hot pokers, then no, he has no pupils after the ordeal.

Do blind people hear better than sighted people?

How well a person can hear largely depends on how intact these hair cells are. Once lost, they don’t grow back – and this is no different for blind people. So blind people can’t physically hear better than others. Yet blind people often outperform sighted people in hearing tasks such as locating the source of sounds.

Do humans have slow reflexes?

D., neurobiologist. Many are faster and no doubt many are slower. The ballpark for human reaction time in ~200 ms. This varies quite a bit, depending on the stimulus, age (I’m lucky to hit 200 ms now), and so on.
