Common Eye Conditions
Are You Experiencing Any of These Eye Conditions?
How powerful our eyes are, though on average the size of the eyeball is only about an inch in diameter and weighs around 0.25 ounces, 80% of sensory information our brains receive is from the eyes. Human eye works much like a digital camera. Light is primarily focused by both the cornea and the crystalline lens then reaches the retina which acts as an electronic image sensor of a digital camera, converting optical images into electronic signals. The optic nerve then transmits these signals to the visual cortex- the part of the brain that controls our sense of sight. Amazingly, they allow us to see 10 million colors. However, many abuse and neglect their eyes.
What is astigmatism?
Astigmatism is a common type of refractive error. It is a condition in which the eye does not focus light evenly onto the retina, the light-sensitive tissue at the back of the eye. Astigmatism frequently occurs with other vision conditions like nearsightedness (myopia) and farsightedness (hyperopia). Together these vision conditions are referred to as refractive errors because they affect how the eyes bend or “refract” light.
What are the causes of astigmatism?
- Result to eye injury or eye surgery
- Rubbing the eyes
What are the signs and symptoms of astigmatism?
- Distorted or blurred vision at all distances
