At Myopia Institute, we believe that taking proper care of your eyes starts with having comprehensive knowledge of how they work. Understanding how the different parts of your eyes work together and coordinate with your brain is important. Today, your vision therapy expert explains how your eyes see.
How Your Visual System Works
Light travels in a straight line until it bounces off an object in your visual field. They will then enter your eyes, first passing through the dome-shaped structure covering your eyes known as the cornea. Its clear, smooth and even features help produce clear and sharp images.
Afterward, the light rays will enter an opening, popularly known as the pupil. It’s surrounded by a colored area known as the iris that controls the pupil size, regulating the amount of light that comes into your eyes. The iris dilates your pupil when you’re in a dim place to admit light as much as possible. When you’re in a bright area, on the other hand, the iris constricts the pupil to prevent overwhelming your sensitive eyes.
The lenses are naturally flexible that allows them to focus the light rays toward your retina. They flatten when you’re looking at something far away and curve when you’re viewing something close. When they harden over time, you may need vision correction to help you see better. The last step includes the retina converting the light rays into nerve signals, which the optic nerve will deliver to the brain for translation.
Ways to Keep Your Eyes in Good Condition
Your eyes are incredible structures that perform a complex function: your sense of sight. This is why it’s important to take good care of them. For one, maintain a healthy lifestyle. Eat foods rich in eye-friendly nutrients, like leafy greens, deepwater fish and citrus fruits. Drink plenty of water every day to keep your eyes lubricated.
Quit sight-threatening habits, like smoking, as early as now. Using sunglasses whenever you’re outdoors is another good idea. Undergoing a complete eye exam regularly is one of the most effective ways to keep your eyes in good shape.
