Eyesight Care
I believe all of us at some point in our existence, have gone through some troubles with our eyes. If you have experienced eyes that are tired, bloodshot, burning, dry, infected, irritated, itchy, sensitive to light, ulcerated, or watery, then information on keeping the eyes healthy will be important to you.
A human eyeball takes the form of a globe and measures almost one inch in diameter. The outer portion of the eye with white color is controlled by six muscles. The eyelid is also controlled by another type of muscle. The face of the eyeball is made up of a transparent layer, which is an extension of the white outer layer. This white outer layer is called the sclera. The membrane underneath the cornea is called the iris. It is dark brown in color that contains the pigment called melanin. The eye has a hole in the middle that has muscles that determines when it contracts and when it expands basing from the amount of light it is exposed to. The eye’s center opening is called the pupil and exactly beneath it is the lens. The eyeball has an innermost layer called the retina.
The act of seeing is actually a complex, multi-step process that goes on continuously and at breathtaking speed. The illumination enters the cornea and body of watery fluid, then through the iris and to the lens, as things are perceived by our eyes. The inversion of the representation of the perceived object happens in the retina. The brain re-interprets this image so that it is perceived upright. There is a concentration of the light on the retina as muscles change the figure of the lens. Corresponding images from both eyes are interpreted by the brain as single, fused image.
Eye disorders are often the result of injury, eyestrain, allergies, and long use of contact lens. Also in numerous cases, eyes may be harmed or vision is impaired by a different cause, which is attributed to another disease. An example is diabetes. Diabetes can trigger the retina and the vitreous to bleed profusely, resulting to sight loss. Early cataracts also may be related to diabetes. For people who suffer high blood pressure, blood vessels in the eyes slowly thickens and as a consequence eyesight is damaged and even lost permanently. Unhealthy eating habits, lack of vitamins and viruses can harm the eyes as well.
A person experiencing watery red eyes with swelling and itching and has pus in its membrane is suffering from conjunctivitis or also called as pinkeye, wherein the lining mucous membrane on the eyelid that covers the white portion of the eye is inflamed. Causes may be by allergy, bacteria, virus, smoke, dust, or chemical irritants. When a person is suffering from an eye disorder caused by a bacteria or a virus, he/she can easily transmit it to other people who he/she comes into contact with. Glaucoma is an eye ailment where fluid pressure in the eye escalates causing the eyeball’s exterior to harden. Aching in the eyes particularly in the morning is a signal that glaucoma is present. Reduced side vision, rainbow halo around lights, and inability to adjust to a darkened room. Further eye disorders consist of iris inflammation, night blindness, Bitot’s Spots, dimness of vision or amblyopia, near-sightedness, far-sightedness, loss of central vision of the eye, eye floaters, dry eyes, diabetic retinopathy, colorblindness, cataracts, obscured vision, eyelid inflammation or blepharitis and astigmatism.
