The eye is a vast and intricate structure that provides one of the most visceral and vital senses to the human experience. In order to properly diagnose and treat any eye condition, we need to understand and study the structure of the eye.
Starting from what we first notice when we see the eye: the iris, the pupil and the crystalline lens to the inner structures of the eye: the cornea, the ciliary body and the vitreous body.
All of these elements and more contributions in the way we see life. In this video, we examine each of these specifics of the eye as we know it; from its location to its function to the way it shapes our vision.
The human eye belongs to a general group of eyes found in nature called” Camera -type eyes" Just as a camera lens focuses light onto film, a structure in the eye called the cornea focuses light onto a light-sensitive membrane called the retina.
It’s a big word, but it simply means your eye isn’t completely round. Almost all of us have it to some degree.
A normal eyeball is shaped like a perfectly round ball. Light comes into it and bends evenly, which gives you a clear view. But if your eye is shaped more like a football or the back of a spoon, light gets bent more in one direction than another. That means only part of an object is in focus. Objects at a distance may look blurry and wavy. It’s fairly easy for an eye doctor to fix with glasses, contacts, or surgery.
Is it hard to see distant objects, like highway signs, until you’re a few feet away, but easy to read a book up close? Chances are you’re myopic, also known as nearsighted. It’s a pretty common condition that your eye doctor usually can fix with eyeglasses, contacts, or eye surgery.
A common refractive vision error, Astigmatism is the focus of the light rays entering the eye on multiple focal points, neither of which is on the Retina, which is needed for correct and healthy vision. This condition is caused by a distortion in the shape of the cornea receiving the light rays.
Astigmatism causes blurred vision, which if left untreated can proceed to increase and decrease vision along with it. There are multiple treatment options for Astigmatism at Magrabi Hospitals including contact lenses prescription, lasik surgery and more.
Open Angle Glaucoma is the most common version of Glaucoma to adults, which can only be detected through regular professional examinations to your eye doctor.
It occurs when the eye’s liquid is not regularly drained out of the eye as fast as it is produced. This causes pressure that eventually reaches the Optic Nerve, causing damage to the impulses reaching the brain.
Aging can be an influential part of the Glaucoma disease cycle. That’s why older people are always advised to regularly visit their eye practitioner.
