What else can I help you with?
If the eyeball is too long images are focused in front of the retina and the result is?
When the light actually reaches the retina the image is blurred (except when looking at close objects when the image is focused on the retina and looks clear. The condition is known as short-sightedness.
What is the innermost layer of the eye called?
The inner rear surface of the eye which contains photoreceptors it called the retina.
What is the sensitive surface of the eye that acts like the film in a camera?
The retina is the sensitive surface of the eye that acts like the film in a camera. It contains specialized cells called photoreceptors that convert light into electrical signals, which are then transmitted to the brain for visual processing.
What kind of disease is central serous retinopathy?
Central serous retinopathy is a condition affecting the retina, typically characterized by fluid accumulation under the central retina. It is often associated with stress, certain medications, or other underlying medical conditions. Central serous retinopathy can result in blurred vision or distortion of images in the central visual field.
What causes myopia and hyperopia?
Nearsightedness and farsightedness are caused by light falling somewhere other than directly on the retina. Normally, light enters the eye through the lens and shines directly on the back of the eye called the retina. This is important because the retina is where all the receptors are, and they convert the light into nerve signals that are sent to the brain. In nearsightedness, light comes through the eye and lands in front of the retina, causing images far away to appear blurred. This can be caused by a curvature in the cornea or lens that is misdirecting the light, or by the shape of the eye itself. If the eye is longer than normal, light may fall in front of the retina. In farsightedness, light falls behind the retina, so that images close up appear blurred.This can also be caused either by the curvature of the lens or cornea, or by the shape of the eye. In the case of farsightedness, the eye may be shorter than normal.
What is the condition in which some portions of an image are in focus on the retina and other portions are blurred is called?
Its the myopia

What is the name of the se rious condition of the retina?
Macular degeneration is a well-known serious condition of the retina.
What is the name for unable to see distant object?
The condition of being unable to see distant objects clearly is called "myopia," commonly known as nearsightedness. In myopia, light entering the eye focuses in front of the retina instead of directly on it, leading to blurred vision for distant objects. This condition can often be corrected with glasses, contact lenses, or refractive surgery.
Why are some words sharp and others blurred when reading is to do with the retina of the eye?
If the area in the center of your vision is blurred, that is likely to be macular degeneration. If everything is blurry especially in strong light, it's likely to be a cataract. In any case, see a doctor.
Why are Visual sensations from images focused on the side of the retina tend to be blurred?
because there are more rods than cones in this region
What is the back of the eye called?
The back of the eye is called the retina. It is a light-sensitive layer of tissue that lines the back of the eye and contains cells that respond to light.
Can the eye sight be damage because of retina condition?
Yes, the retina is a pivotal part of the eyes ability to see.
Where is the image formed in myopia?
In myopia, the image is formed in front of the retina, resulting in blurred vision. This occurs because the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina instead of directly on it.
What is the medical term meaning any error in which images do not focus properly on the retina?
The medical term for this condition is "refractive error." Refractive errors occur when the shape of the eye prevents light from focusing directly on the retina, leading to blurred vision. Some common types of refractive errors include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
What is an eye condition in which images appear wavy or blurry?
An eye condition where images appear wavy or blurry is called macular degeneration, specifically age-related macular degeneration (AMD). This condition affects the macula, the central part of the retina responsible for sharp vision, leading to distortion or loss of central vision. Patients may experience wavy lines or blurred images, making tasks like reading and recognizing faces challenging. Early detection and management are crucial to slowing its progression.
What would happen if we had no lens?
If we had no lens in our eyes, the light entering our eye would not be focused onto the retina, causing blurred vision. The lens plays a vital role in adjusting the focus of incoming light to create a clear image on the retina.
