Sometimes someone's eyeball shape makes it difficult for the cornea, lens, and retina to work perfectly as a team. When this happens, some of what the person sees will be out of focus. To correct this fuzzy vision, many people, including many kids, wear glasses.
Ever wonder how your eyes work? This article for kids takes you from the pupil to the retina and beyond.The white part of the eyeball is called the sclera (say: SKLAIR-uh). The sclera is made of a tough material and has the important job of covering most of the eyeball. Think of the sclera as your eyeball's outer coat. Look very closely at the white of the eye, and you'll see lines that look like tiny pink threads.The biggest part of the eye sits behind the lens and is called the vitreous (say: VIH-tree-us) body. The vitreous body forms two thirds of the eye's volume and gives the eye its shape. It's filled with a clear, jelly-like material called the vitreous humor. Ever touch toy eyeballs in a store?The lens' job is to focus light rays on the back of the eyeball — a part called the retina (say: RET-i-nuh).
Jaguar’s polarizing teaser video of the car brand’s makeover achieved exactly what it set out to do, according to its managing director: attract attention.
The tap would tighten a band of artificial muscle wrapped round your eyeballs, changing their shape and bringing blurry images into focus. While the idea has a high ‘yuk’ factor, the people behind it are confident it will be a safe and effective way to improve vision.
A tap on the side of the head would tighten a band of artificial muscle wrapped round your eyeballsMost of the eye’s focusing is done by the cornea, the hard transparent surface that covers both the pupil and the iris; the lens is responsible only for fine-tuning. Light travels through the cornea and lens to focus on the retina at the back of the eyeball.Stitching a band of artificial muscle to your eyeball sounds drastic, but Shahinpoor says the necessary surgical techniques are already commonly used for treating detached retinas. He claims his smart eye band is far more flexible than laser surgery, in which a laser flattens the cornea by eroding part of it.If the cornea or lens do not focus strongly enough or the eyeball is too short, the light will focus behind the retina, blurring images of close-up objects. This is long-sightedness.
The 77-year-old said he was healing from the infection, but that his recovery would take "some time".
Sir Elton John says he has been left with "only limited vision" in one eye after a "severe" infection."Over the summer, I've been dealing with a severe eye infection that has unfortunately left me with only limited vision in one eye," he wrote on Instagram.

We talk a lot about the importance of eye health, and the impact of screens and tech on vision, but we rarely directly compare the two. At the unveiling of an educational exhibit called "The Eye" Thursday (which is exactly what it sounds like -- a giant prototype of a human eyeball), the American Optometric Association made the case that we should be valuing our eyesight's capabilities with equal interest as the latest camera or OS update.Optometrists are using The Eye prototype to prompt people to get eye exams, but the unveiling really highlighted room for future research on technology's impact on vision. GIF by Jessica Rendall/CNET · Through The Eye, built for display in New York this weekend, the AOA also seems to be positioning the eye's likeness to tech as a tool of sorts to remind people to go in for eye exams, which is a good idea for most people at least once a year. But most notable was how the giant eyeball prototype, and all the tech buzz around it, also called attention to a lack of long-term research around consumer technology's impact on vision health -- at least compared to the growth of tech itself and the amount of time it demands from our eyes.Research hasn't linked long-term vision problems with tech use, but it also can't keep up with the rate of new technology and all the time we spend with it.Judner Aura, a tech reviews content creator and panelist at The Eye's unveiling, called attention to the lack of education around vision health, adding that he's looking forward to "increased language" around vision health and consumer technology.

The muscles hold the lens in place but they also play an important role in vision. When the muscles relax, they pull on and flatten the lens, allowing the eye to see objects that are far away. To see closer objects clearly, the ciliary muscle must contract in order to thicken the lens. The interior chamber of the eyeball is filled with a jelly-like tissue called the vitreous humor.The outermost layer, called the sclera, is what gives most of the eyeball its white color. The cornea is also a part of the outer layer. The middle layer between the retina and sclera is called the choroid. The choroid contains blood vessels that supply the retina with nutrients and oxygen and remove its waste products.

Keratopigmentation is often performed to correct a cosmetic disfigurement – corneal clouding, say, caused by disease or injury. Occasionally, it’s deployed to improve the vision of a damaged iris.
An unusual treatment that involves permanently changing the color of their eyes through an unusual cosmetic surgery procedure is soaring in popularity.
The US Food and Drug Administration has yet to approve keratopgimentation as a procedure in the US. But that hasn't stopped surgeons from finding workarounds: some are using lasers designed for vision correction off-label and buying dyes from companies overseas where they're certified, the WSJ reports."No surgery is free of risk," AAO clinical spokesperson JoAnn Giaconi in a statement at the time. "With purely cosmetic surgeries on the eye, it’s just not worth the risk when it comes to your good vision."
