What else can I help you with?
The condition in which some portions of an image are in focus on the retina and other portions are blurred is called?
That is usually caused by irregular curvature of the cornea and referred to as astigmatism. It is a very common eye condition and can be corrected with lenses or surgery.
What is the name of the se rious condition of the retina?
Macular degeneration is a well-known serious condition of the retina.
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.
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
Can the eye sight be damage because of retina condition?
Yes, the retina is a pivotal part of the eyes ability to see.
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.
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 the innermost layer of the eye called?
The inner rear surface of the eye which contains photoreceptors it called the retina.
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.
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.
