Objects look blurry when they are not in focus on the retina of the eye. This can happen due to a refractive error in the eye, such as myopia (nearsightedness) or hyperopia (farsightedness), or if the lens of the eye cannot adjust properly to focus the light. Additionally, factors like aging, certain medical conditions, or drugs can also contribute to blurry vision.

Why are things in water are blurry?
Things in water appear blurry because the light passing through water refracts, or bends, due to the change in density between water and air. This refraction causes the light rays to scatter, resulting in the blurry or distorted appearance of objects when viewed underwater.
What is most common refractive error?
The most common refractive error is myopia, also known as nearsightedness. This condition causes distant objects to appear blurry, while close-up objects can be seen more clearly. It is usually caused by the eyeball being too long or the cornea being too curved.
What type of lens makes objects look smaller?
A concave lens makes objects look smaller. This type of lens diverges light rays, which causes the image to appear smaller than the actual object.
Why do objects look larger under water?
Objects appear larger underwater due to the refractive index of water. This causes light rays to bend as they pass through water, which makes objects look closer and larger than they actually are. Additionally, the distortion caused by the water can magnify the appearance of objects.
What happens when you look through a concave lens?
When you look through a concave lens, objects may appear smaller and closer than they actually are. This type of lens causes light rays to diverge, resulting in a virtual image that is upright and reduced in size. However, the image may appear blurry due to the spread of light rays.
What is it when you look at something and everything else is blurry?
When you look at something and everything else is blurry, it indicates a condition called myopia or nearsightedness. Myopia causes difficulty in focusing on objects at a distance while objects closer to you may appear clearer. It is a common refractive error that can be corrected with glasses, contact lenses, or surgery.
Is a condition in which faraway objects appear clear while near objects look blurry?
Farsightedness
Why are things in water are blurry?
Things in water appear blurry because the light passing through water refracts, or bends, due to the change in density between water and air. This refraction causes the light rays to scatter, resulting in the blurry or distorted appearance of objects when viewed underwater.
What is a person called who can see distant objects clearly but for whom nearby objects appear blurry?
A person who can see distant objects clearly but has blurry vision for nearby objects is experiencing nearsightedness, also known as myopia. This is a common refractive error in which the eye focuses light in front of the retina instead of on it, causing close-up objects to appear blurry.
What condition of the eye causes the leans go blurry?
cataracts
What does it look like when you need glasses?
blurry
What is the transparence of an emerald?
Emeralds can be:TransparentTransparent is given when objects seen through an emerald look clear and distinct. Such emeralds usually have excellent brilliance, even if they might have some minor inclusions.orSemi-transparentSemi-transparant is given to emeralds when objects look slightly hazy or blurry through the stone.
Do the pictures seen in the pinhole camera show the colour of the objects on the other side?
The pictures that are seen in the pinhole camera usually show the colors of the objects in front of the camera. The images usually look slightly blurry compared to the real colors.
What condition occurs when the eyeball is too long?
Myopia, or nearsightedness, occurs when the eyeball is too long. This causes light to focus in front of the retina instead of directly on it, resulting in distant objects appearing blurry.
What causes the mnotion of objects?
what causes the motion of objects
Who are people that can see things close to them but distance objects are blurry and difficult to see?
nearsided people
What happens if the light is focused behind or in front of the retina?
If the light is focused behind the retina, it causes nearsightedness (myopia), where distant objects appear blurry. If the light is focused in front of the retina, it causes farsightedness (hyperopia), making close objects appear blurry. Both conditions can be corrected with glasses, contacts, or refractive surgery.
