In this case, the distant objects are clear while nearby objects appear blurry.<\/li>\n<li>In this condition, the light is focused behind the retina rather than on the retina. This defect results due to the eyeball being smaller than usual. So the distance between the lens and retina is smaller than it should be in a normal eye.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" class=\"aligncenter wp-image-133618 size-full\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/img-1646330487972.jpg\" alt=\"\" width=\"318\" height=\"319\" srcset=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/img-1646330487972.jpg?v=1646330489 318w, https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/img-1646330487972-300x300.jpg?v=1646330489 300w, https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/img-1646330487972-150x150.jpg?v=1646330489 150w\" sizes=\"(max-width: 318px) 100vw, 318px\" \/><\/p>\n<p><strong>Hyperopia<\/strong><\/p>\n<ul>\n<li>Hyperopia can be corrected using a convex lens which helps in focussing the light at the correct place.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Table of Contents Hyperopia Astigmatism Presbyopia Summary What\u2019s Next?
