Depth perception describes the eyes’ ability to determine the distance between objects. Both eyes perceive the same object a bit differently and at a different angle. The brain is able to merge both images into a single 3-D image in a process called stereopsis. This information allows one to determine how far the objects are, as well as how far apart they are from each other. People with poor depth perception lack the ability to process the information correctly.
Are you experiencing blurred or double vision? Twelve various eye muscles coordinate your eyes’ movements and position your focus on the visual target. If one of the muscles gets somewhat weak, you might experience headaches, double vision, or eye strain. If your eye doctor detects frailty in your eye muscles, they can add a prism to your usual lenses to ease the strain on your eyes.
Double vision, or diplopia, is a condition causing you to see two overlapping or separate images of the same object. Double vision can turn simple tasks into challenges. The act of reaching for a glass of water can be difficult when you see two glasses instead of one. If you suffer from double vision, you might experience poor depth perception. It affects your ability to drive, read, and play sports. The condition can interfere with your quality of life.
Many individuals who experience migraines also have problems with vertigo and vision. These symptoms can be quite scary. With the right treatment, however, they can disappear or get better. Many different factors can cause dizziness and headaches. Fortunately, complementary therapies, medications, and lifestyle changes can help reduce migraines and their related symptoms.
Eye allergies, also known as allergic conjunctivitis, are fairly common and occur when the eyes come into contact with a substance that your immune system perceives to be harmful. This substance is known as an allergen. When an allergen reaches the eyes, the body produces chemicals called histamines to protect you. It’s the release of these histamines that causes the symptoms that are commonly associated with an allergic reaction. Living with eye allergies can be frustrating, but there are things that you can do to minimize the likelihood of you experiencing a reaction. There are also treatments that can alleviate your symptoms.
A normal cornea is dome-shaped and looks like a ball. The cornea is the front surface that shields the interior of the eyeball. But, sometimes, its structure thins out and is no longer able to hold the round shape. The result is an outward bulge giving the cornea a cone shape. This condition is called Keratoconus. It affects both eyes, but usually, one is more affected than the other.
Safety on the roads doesn’t only depend on the condition of the vehicle you are driving or the weather conditions. Driving also requires exceptional visual skills. You need to be able to see objects in front of you and around you and respond quickly to them – for example watching and anticipating another vehicle changing lanes or pulling out of a side road in front of you, having enough peripheral vision and awareness to know when another vehicle is going to overtake you, or watching for pedestrians, bikes and other hazards. As such, it’s not surprising that most countries require drivers to meet certain visual standards in order to legally get behind the wheel.
Diabetic retinopathy is an eye complication resulting from diabetes. Blood vessels in the retina are damaged causing vision complications. Mild diabetic retinopathy causes controllable vision complications. However if left untreated, severe cases lead to vision loss. This condition affects people with type one and types two diabetes. Too much blood sugar blocks the tiny eye vessels in the retina. They leak into the retina causing vision complications. Nerves and fibers in the retina react by swelling and you develop macular edema. Eventually, the eye can develop scar tissue and damage the optic nerve, resulting in glaucoma.
There are many symptoms and issues that can be treated by your eye doctor, and in many cases, is actually better placed to diagnose and treat your condition. This is because eye doctors have undergone specific education and training in order to be able to specialize in the detection and treatment of conditions related to the eyes. Dizziness and headaches are two common neurological problems that an eye doctor can help with.
The function of the retina is to receive light that is focused by the lens of the eye and passes through it and then converting the light into signals which are sent to the brain which then tells us what we can see. Unsurprisingly, its function makes the retina one of the most important parts of our eye and essential for our vision. If it becomes damaged or affected by the disease, it could stop working properly causing temporary or even permanent vision loss. Fortunately, it is possible to preserve the health of your retina and maintain your vision for longer thanks to MacuHealth.
