Light rays bend when they enter from one medium to another of different density. The amount of bending is determined by the refractive indices of the two media. If one medium has a particular curved shape, it functions as a lens. The cornea, humours, and crystalline lens of the eye together form a lens that focuses images on the retina. Our eyes are adapted for viewing in air. Water, however, has approximately the same refractive index as the cornea (both about 1.33), effectively eliminating the cornea's focusing properties. When our eyes are in water, instead of their focusing images on the retina, they now focus them far behind the retina, resulting in an extremely blurred image from hypermetropia.

Why will goggles allow a swimmer underwater to focus more clearly on what he is looking at?
Goggles provide a barrier that prevents water from distorting the swimmer's vision, allowing them to see clearly underwater. The air inside the goggles creates a flat surface for light to pass through, reducing the refractive effects that occur when light enters water, which contributes to better focusing and clarity.
If you look through a sniper scope with night vision goggles will the picture be in night vision?
Yes it will, it may be you need to focus the goggles on the scope to make it a bit easier, and its a bit awkward because the goggles can bang into the scope. But I have mounted my 3 to 9 leupold day scope well forward on my AR 15 and I can easily look through and identify the target and hold the cross hairs on it, without any IR light. Short answer is YES!!
Can humans fly if they focus enough?
ANSWERNo. ANSWERWhether fortunate or unfortunate, humans cannot fly no matter how hard one may focus.
What did early humans focus on to explain their daily lives?
food
Are night vision goggles convex or concave?
Night vision goggles typically use convex lenses to gather and focus incoming light in order to improve visibility in low-light conditions. These lenses help to magnify the available light and provide a clearer image for the user.
Why refraction is important to a crocodile?
Crocodiles are amphibious reptiles which hunt prey both on land and in water. Previous refractive studies have suggested that their eyes can focus objects in air and that their ability to refocus the eye underwater may be limited. Examination of the plane of focus of six species of crocodiles both in air and underwater has revealed that they are generally well focused in air for distant targets and severely defocused underwater. These results suggest that sensory systems other than vision must play an important role in prey capture underwater.
