A Guide To Eyeglass Repair
Most reptiles cannot focus properly by shifting the shape of their eye lens to and fro and have to move their eye lens constantly back and forth, making them highly sensitive to motion and reduces them from focusing accurately on moving objects. This is one of the reasons why they love to run. You can tell that your snake is moving because it keeps shifting its position. As a result, you can know that your snake is not sleeping well. And if you have an eye problem, moving your snakes can help you by relieving the stress caused by your eye problem.
Moving the eye lens is called C interpersonal osteoarthritis.
It is also known as Blurry Vision because the patient is unable to perceive contrast, color, or clear vision. When your eye lens moves out of place, it causes discomfort in your eyes because it interferes with your retina. If this problem is not addressed quickly, it can lead to loss of eyesight which may cause a need for eyeglasses or contact lenses.
Snakes use two types of lenses, a bifocal lens, and a crystalline lens.
The bifocal lens is similar to the human eye in its structure and functions. It consists of two parts including the superior and the posterior capsule. The two parts are separated by a thin membrane called the choroid. The posterior capsule covers the retina and the superior capsule cover the lens and the eye. Both parts are named aqueous humor.
The choroid contains the primary cilia
which pulls the lens towards the eye and pushes it out of the eye. The crystalline lens epithelial cells sit on top of these cilia and divide multiple times a day. These cells make new lens fibers along with fluid-filled channels between the fibers.
When one or more of these choroid cells
become detached from the lens, they float around inside the eye and cause blurred vision or double vision. The choroid has two major functions in the eye. One, it acts as a funnel to drain fluid buildup under the retina to avoid blurred vision, and two, it produces new lens fibers. In the event of detachment, however, the process stops functioning properly.
Removing a detached lens
is done by cutting a small flap in the cornea with a surgical knife. The flap causes the anterior chamber of the cornea to clear so that the crystalline lens can replace the anterior chamber. It takes about thirty seconds for the corneal tissue to heal but vision returns to normal over time. About twenty-five percent of people with crossed eyes also experience double vision.
