Look After Your Eyes - Have A Portable Ophthalmoscope
Everyone at one time or another has experienced some sort of eye discomfort. If you are experiencing some of the common eye disorders such as bloodshot eyes, tired, burning, dry, infected, irritated, itchy, light sensitive, ulcerated, or watery, so therefore knowledge on how to care for your eyes is of use to you.
The human eyeball is approximately an inch in diameter and spherical in shape. The white coating of the eye is attached to six muscles that control the eye's movement and another one that controls the eyelid. The cornea is a clear transparent layer at the front of the eyeball and is an extension of the white of the eye or sclera. The iris is the layer situated under the cornea. its dark brown color contains melanin, a pigment that establishes the eyes' color. The circular part of the eye, the iris, is responsible for controlling the diameter and size of the hole and the amount of light reaching the inner layer of the eye. Pupil is the term used for the eye's small opening in the middle. The lens precisely lies beneath it. The eyeball has an innermost layer called the retina.
How the eyes function incessantly at an astounding velocity is quite intricate. In perceiving an object, light rays go through the cornea and body of watery fluid, and through the iris to the lens. The lens inverts the image on the retina, turning it upside down. The image is then inferred by the brain as it was in its original position. Eye muscles alter the form of the lens as it directs the illumination accurately on the retina. Images on each eye is considered a single, combined image as the brain understands it.
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. The start of cataract may also be associated with diabetes. The blood vessels in the eyes slowly solidifies triggered by the condition of having high blood pressure therefore harming one's vision and even losing it. Viral infections, regularly eating foods with no nutritional value and deficiency in vitamin intake are also the causes of vision impairment.
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. It may have triggered by allergy, bacteria, virus, smoke, dust or chemical irritants. Bacterial or viral infections are highly contagious. If a person has glaucoma, he/she is likely to go blind because as the fluid pressure inside the eyeball intensifies, it destroys the optic nerves. The eyes hurting especially in the morning is a sign that a person has glaucoma. Reduced side vision, rainbow halo around lights, and inability to adjust to a darkened room. Iris irritation, far-sightedness, near-sightedness, keratin debris build-up on the conjunctiva or Bitot's Spots, lazy eye or amblyopia, macular damage, eye's vitreous humour deposits, diabetic retinopathy, colorblindness, cataracts, blurred vision, eyelids inflammation, and astigmatism are other forms of eye disorders.
