Few body parts are as essential to your life’s enjoyment as the eyes. These allow you to appreciate various things and handle multiple activities of daily living. A nationwide survey found out that most people believe that the worst outcome of most health issues they might be battling is the loss of vision. Unfortunately, vision loss is still among the leading complications of most diseases. One of the most common eye conditions nowadays is peripheral vision loss or tunnel vision.
The primary approach for correcting tunnel vision lies in smart glass eyewear that has prisms. The condition is characterized by the loss of the ability to see things on either side of your vision or along its upper and lower sides. This explains its ‘tunnel vision’ name. The prism added to the eyeglass lens expands the field of view of people suffering from this condition. In so doing, the patient regains a wide field of vision. Here are some of conditions that often lead to peripheral vision loss.
Glaucoma
This is the leading cause of tunnel vision. It arises from a rise in the pressure behind your eye, such that it eventually damages your optic nerve. With this eventuality, people with glaucoma experience ‘’blind spots’’ around their visual field. Other than tunnel vision, glaucoma will lead to cloudy and blurred vision, seeing of halos around lights and severe projectile vomiting. The projectile vomiting, when coupled with eye pain, is an indicator of increased pressure in your brain and should be promptly checked before it causes brain damage and vision loss.
Cataracts
These result from clumping of the proteins that constitute your eye. This clumping eventually clouds your vision and affects your vision field. There is one type of cataract that starts in your eye’s centers and forms a nuclear cataract. Even so, most start from the sides of your eyes and will often cause peripheral vision loss. Extra light sensitivity, seeing colored objects as yellowish or faded, and problems with night vision are the other common symptoms of cataracts.
Retinitis Pigmentosa
This is a progressive eye condition that affects the retina’s light-sensitive cells. The retina conveys the visual information that has been collected by your eyes to the brain. The effect on your retain will often start as a peripheral vision loss. Some people also experience night blindness that progresses to color blindness. Most cases of retinitis pigmentosa are linked to genetics, and there is currently no definitive treatment for the same.
Stroke
More and more people nowadays are getting strokes because of uncontrolled hypertension. In these cases, blood flow to the brain is disrupted, and your brain is depleted of oxygen and nutrients. Depending on the timeframe between the start of a stroke and restoration of blood flow, you suffer different effects. One of the common effects of a stroke is peripheral vision loss.
A prism for your eyeglasses is the best choice for managing tunnel vision from the above causes. At times, however, the peripheral vision loss is only temporary. This is often in vasovagal syncope when suddenly rising from a sitting or sleeping position and extreme panic or emotional stress.
