These conditions are sufficiently confusing without adding similar-sounding names into the mix! But both hyperopia and presbyopia are common.

And another question, is hypermetropia and presbyopia same?

Hyperopia, also known as farsightedness, is a condition wherepeople are able to see distant objects clearly but objects up close seem blurry. Hyperopia can occur at any age, and it is often there after birth. Presbyopia is a condition where people see blurred when looking at close objects even with glasses. People also ask is presbyopia the same as hyperopia? Farsightedness (hyperopia) is often confused with presbyopia, but the two are different. Presbyopia occurs when the eye's lens loses flexibility. Farsightedness occurs when the eyeball is too short. This results in an underfocused image that requires the help of the lens to re-focus it.

Can you live with no eyes?

You don't need eyes to surviv. Some people may lose an eye due to an injury or have one removed because of cancer. In rare cases, a person could be born without them. While a lack of eyes can create many challenges for a person, they technically aren't a vital organ for survival. What if all humans were blind? If we all suddenly went blind, the vast majority of humanity would die quickly as we'd lose almost all infrastructure, communication, and ability to survive without such things.

Also, can a blind society survive?

How has humanity survived? Yes, some species evolve without the use of much sight ? moles, bats etc ? but they make up for that thanks to greater sensitivity in their other senses, other abilities humans don't have (like echolocation) as well as the particular environments they live in.
