    Solution:

    Concept- Hypermetropia is rectified by convex lens. We are expected to identify the flaws in eyes and how to fix them in this inquiry. In order to answer this query, we will talk about eye problems. We'll also talk about a couple of the causes of these eye abnormalities. This will assist us in comprehending how to cure or reverse these impacts. Therefore, we will also talk about how to fix them.
    Macular degeneration, cataracts, or glaucoma are just a few of the eye conditions that can cause problems. 1) Myopia is the main eye defect. Two) Hyperopia Third, astigmatism No. 4 Presbyopia
    In myopia, the near item may be seen clearly but the far object appears to be blurred. Now, because the eyeball is significantly longer, the picture is focused in front of the retina rather than on it, which is why this occurs. The value of the recommended lens to treat myopia is negative. As can be seen in the graphic below, myopia may be treated by employing a concave lens to concentrate the image in the retina.
    Similar to this, with Hyperopia distant items can be seen clearly but objects close by are blurry. Now, either the eyeball is significantly shorter or the eye's lens has a less refractive strength, the picture is focused behind the retina rather than on it. The recommended lens is effective in treating myopia. In order to concentrate pictures in the retina, a convex lens can be used, as illustrated in the figure below, to treat hyperopia.
    When the light rays do not strike the retina at a single focal point, astigmatism develops. The irregularity in the cornea's curve causes this problem. A specific spherical cylindrical lens that is positioned outside of the axis' focus can be used to rectify it.
    The natural thickening or deterioration of the eye's lens is known as presbyopia. It is a flaw that often develops with aging. With the right glasses, it may be seen well.This defect can be corrected by using a convex lens of appropriate power. Eye-glasses with converging lenses provide the additional focussing power required for forming the image on the retina.
    Hence, the answer is convex lenses.
