When light changes from traveling in one medium to another, it will 'bend' or refract. However, water and your eye basically have the same refractive index, so the light will barely bend (unlike in air.) Your lens can't properly compensate for the lack of the refraction, so a normal person would become more farsighted, a farsighted person would become even more farsighted. However, a severely nearsighted person would get closer to normal as their eye defects compensate more for the lack of refraction.

Can pelicans see underwater?
Pelicans have relatively poor underwater vision compared to their excellent aerial vision. Their eyes are adapted for spotting fish from above the water's surface, but they lack the necessary adaptations for clear vision underwater. When they dive to catch fish, they rely more on their other senses and their ability to judge distances rather than on sight. Therefore, while they can see some movement underwater, their vision is not optimized for that environment.
Who has better peripheral vision older or younger people?
Younger people tend to have better peripheral vision than older people, as age-related changes such as reduced eye muscle flexibility and overall eye health can affect peripheral vision. However, individual differences and factors such as eye health and lifestyle habits can also influence peripheral vision abilities.

Does night vision work underwater?
Night vision devices are primarily designed for use in low-light conditions on land and may not perform well underwater. They rely on ambient light, such as moonlight or starlight, to amplify images, which is significantly reduced underwater due to light absorption and scattering. Instead, underwater environments typically use specialized lighting, such as underwater cameras with built-in lights, or infrared systems designed for aquatic use. Thus, traditional night vision is generally ineffective for underwater applications.
what kind of eye exercises will help nearsighted people?

What are the different types of eye ball shapes and how do they affect vision?
There are three main types of eye shapes: normal, nearsighted (myopic), and farsighted (hyperopic). The shape of the eye affects how light is focused on the retina, which can impact vision. Nearsighted eyes are longer than normal, causing distant objects to appear blurry. Farsighted eyes are shorter than normal, making close-up objects blurry. Normal eyes have a balanced shape for clear vision at various distances.
How effective is lasik?
Lasik is a very effective eye surgery. Nearsighted or farsighted patients usually get excellent results with Lasik vision correction procedure.

The FDA found that complications take place in 1% to 5% of Lasik procedures.
