Answer:
1.) Cataract
2.) Astigmatism
3.) Dry Eyes
4.) Presbyopia
5.) Myopia
6.) Hypermetropia
Explanation:
1.) A cataract is a clouding or opaque area over the lens of the eye - an area that is normally transparent. As this thickening occurs, it prevents light rays from passing through the lens and focusing on the retina - the light sensitive tissue lining located in the back of the eye.
2.) In Astigmatism,Vision becomes distorted when the surface of the cornea has an uneven curvature. Sometimes it is the eye's lens that is irregularly shaped. This type of irregularity causes light to focus on more than one spot of the eye, resulting in blurred vision.
3.)In Dry Eyes,Eye problems are some of the most well-known issues related to vitamin A deficiency. In extreme cases, not getting enough vitamin A can lead to complete blindness or dying corneas, which are characterized by marks called Bitot's spots.
4.) Presbyopia is a vision condition in which the lens loses its flexibility, making it difficult to focus on close objects. During the early and middle years of life, the crystalline lens of the eye has the ability to focus both near and distant images by getting thicker for near objects and thinner for distant objects. When this ability is lost, presbyopia results.
5.) Myopia results when the eye ball is lengthened from front to back or the lens is too curved.
6.) When the eye ball becomes too short or lens get flattened, light rays instead of getting focussed on the retina, get focussed behind the retina. Hence, the image is formed behind the retina. This condition is called hypermetropia, also known as long-sightedness. In this disorder, vision of nearby objects gets blurred
