For a healthy eye, this distance is theoretically infinite, as parallel rays from distant objects focus precisely on the retina without strain.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The human eye is a complex sensory organ that enables vision by detecting light and converting it into electrical signals for the brain to interpret.<\/p>\n","protected":false},"author":9,"featured_media":15261,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[63],"tags":[72],"class_list":["post-15195","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-science-and-technology","tag-gs-3"],"_links":{"self":[{"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/posts\/15195","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/comments?post=15195"}],"version-history":[{"count":2,"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/posts\/15195\/revisions"}],"predecessor-version":[{"id":15263,"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/posts\/15195\/revisions\/15263"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/media\/15261"}],"wp:attachment":[{"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/media?parent=15195"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/categories?post=15195"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.nextias.com\/blog\/wp-json\/wp\/v2\/tags?post=15195"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
