Read the passage in the human eye and answer the questions.
Eye is a natural optical device by which humans could see objects around him. It forms an inverted, real image on a light sensitive surface. It works on the phenomenon of refraction of light through a natural convex lens. However, Meena was unable to see clearly the words written on the black board placed at a distance of approximately 3 m from her. Her mother discussed the same with the doctor. Doctor explained to her about this defect of vision and its correction.

The human eye is a fascinating organ that allows us to see the world around us. It acts as a natural optical device, forming an inverted and real image on a light-sensitive surface. This process is made possible through the phenomenon of refraction of light, which occurs when light passes through a natural convex lens in the eye.
In the given passage, Meena is experiencing difficulty in seeing clearly the words written on a blackboard placed at a distance of approximately 3 meters from her. To understand the reason behind this vision defect and its correction, Meena's mother consults a doctor.
The doctor explains that the image of the object is formed at the retina of the eye. Let's further delve into the details of the different parts of the eye and their role in vision:
1. Cornea: The cornea is the clear, transparent front surface of the eye. It acts as a protective covering and also helps in focusing light rays onto the retina.
2. Iris: The iris is the colored part of the eye that controls the size of the pupil. It adjusts the amount of light entering the eye by changing the size of the pupil.
3. Pupil: The pupil is the black circular opening in the center of the iris. It regulates the amount of light entering the eye. In bright light, the pupil constricts, and in dim light, it dilates to allow more light to enter.
4. Retina: The retina is a layer of light-sensitive cells located at the back of the eye. It contains specialized cells called photoreceptors (rods and cones) that convert light into electrical signals. These signals are then transmitted to the brain via the optic nerve, where they are interpreted as visual images.
Based on the given information, the doctor correctly states that the image of the object is formed at the retina. This is because the retina is the innermost layer of the eye that contains the light-sensitive cells responsible for capturing the image and converting it into electrical signals.
In cases where a person is unable to see clearly at a distance, such as Meena's difficulty in reading the words on the blackboard, it is likely due to a refractive error. Refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), or astigmatism, occur when the light entering the eye does not focus properly on the retina. Glasses, contact lenses, or refractive surgery can be used to correct these vision problems.
In conclusion, the human eye forms the image of an object at the retina. Understanding the different parts of the eye and their functions helps us comprehend how vision works and how vision defects can be corrected.
