With reference to hypermetropia, which of the following statements is/...
- Hypermetropia is also known as far-sightedness. It is a form of refractive error in which parallel rays of light coming from infinity are focused behind the light-sensitive layer of the retina when the eye is at rest. Hence statement 1 is correct.
- A person with hypermetropia can see distant objects clearly but cannot see nearby objects distinctly. The near point for the person is farther away from the normal near point. This is because in hypermetropia, the cornea is flatter or the axial length is too short. Therefore, the images do not focus by the time they reach the retina. Hence statement 2 is correct.
- This defect arises either because: the focal length of the eye lens is too long or the eyeball has become too small. This defect can be corrected by using a convex (outward facing) lens of appropriate power. Eyeglasses with converging lenses provide the additional focusing power required for forming the image on the retina. Hence statement 3 is not correct.

With reference to hypermetropia, which of the following statements is/...
Hypermetropia, also known as farsightedness, is a common refractive error that affects the ability of the eye to focus on nearby objects. Let's discuss the correct statements about hypermetropia:
- Parallel rays focused behind the retina:
In hypermetropia, parallel rays of light coming from infinity are focused behind the retina instead of directly on it. This occurs because the eyeball is too short or the cornea has too little curvature, causing light to focus beyond the retina. This results in difficulty focusing on close-up objects.
- People with a flatter cornea:
Individuals with hypermetropia typically have a flatter cornea compared to those with normal vision. The flatter cornea causes light entering the eye to be focused behind the retina, leading to blurred vision, especially when looking at nearby objects.
- Correction with a concave lens:
Hypermetropia is corrected using a concave lens, which diverges incoming light rays before they enter the eye. By using a concave lens, the focal point of light is shifted forward onto the retina, allowing individuals with hypermetropia to see distant and close-up objects more clearly.
In conclusion, the correct statements about hypermetropia are that parallel rays of light focus behind the retina and individuals with hypermetropia often have a flatter cornea. This condition is commonly corrected using a concave lens to adjust the focal point of light onto the retina, improving vision for individuals with hypermetropia.
