By Edited Sep 6, 2016 0 0

Poor night vision

So you have difficulties seeing well at night? Fact is you are among millions of people who have poor night vision around the world. Difficulties seeing at night are just but the initial sign of cataracts that are in their advanced stage. Extreme cases of poor vision at night can be detrimental since they can cause night blindness. 

Reduced vision at night could as well be an indicator that you’re suffering from other eye related hereditary problems which may include retinitis pigmentosa or more severe problems. Reduced night vision can be corrected if medical attention is sought early enough when the condition has not deteriorated. 

What Exactly Causes Poor Night Vision?

It’s difficult to analyze reduced vision at night without having to look at what causes it in the first place. Research has shown that causes of reduced night vision emanate from a wide range of causes which range from exposing the eyes to long hours of sunshine to lack of important vitamins in the body to chronic conditions such as diabetes. Below is a comprehensive look of major causes that have been linked to poor vision at night. 

Cataracts… The lens, which are situated behind they eye’s pupil experience a cells turnover over a lifetime. This is a natural, self-regulating process that is meant to refresh the eyes cells and replace damaged cells. Over time the worn out cells form piles of waste in the eye. This buildup of dead cells leads to formation of cataracts. It is difficult to know when cataracts are forming in the eye because this is a slow, usually progressive and painless process. The cataracts eventually clog the lens.

The initial indicator of cataracts is most of the time decreased vision at night. A patient will experience alteration of light brought about by the cataracts. This distortion produces hue around lights particularly at night. Farsightedness and nearsightedness is also rampant when cataracts form in the eye. 

Lack of Vitamin A… Vitamin A, mostly found in carrots and green or yellow leafy vegetable is a crucial vitamin that is known to make eyesight better. Apart from improving eyesight, it also maintains the Retina normally situated at the back of the eye in a healthy state. Although lack of vitamin A is not a common cause of poor night vision, a good number of people who have been diagnosed with this condition have be found to have insufficient levels of vitamin A in their bodies.

Vitamin A deficiency mostly happens to people who have digestion problems which mean that the body doesn’t absorb the vitamin from the digestion tract. They body may not be able to absorb vitamins for the digestive tract owing to a number of conditions such as pancreatic insufficiency, celieac disease and Crohn disease. 

Diabetes… Research shows that if you have diabetes then your chances of suffering from poor vision at night are high. High levels of blood in the sugar eventually become toxic and end up causing damage to the nerves in the eye and blood vessels as well. Damage is caused to the retina, the part of the eye where focusing of images takes place. This is a condition known as Retinopathy. Early indicators of this condition are reduced vision at night and not being able to see after getting into a room from bright sunlight outside. 

Lack of Sufficient Zinc… Zinc and Vitamin A work hand in hand to keep the eye healthy. Vitamin A alone is not as affective when there is a Zinc deficiency. As a result you may suffer from reduced night vision if the Zinc levels in the body are low. To up the Zinc in your body, beef, poultry and beans are some of the foods you may consider eating. 

Over Exposure to Sunlight… Have you experienced blurred vision at night after spending a considerable amount of time in the sun? This is a clear indicator that the UV rays are tampering with your eyesight. So risky is exposing your eyes to long hours of sun that it can interfere with your ability to see at night for even up to 48 hours. To make sure that you’re always protected, doctor’s advice that you wear sunglasses on a regular basis.

Retinitis Pigmentosa… This is a relatively rare congenital disorder. This condition mostly occurs in young adults especially those who are within the 20-30 years age bracket. The earliest indicator that you are suffering from this condition is poor night vision. This is followed by a massive loss of eyesight which may ultimately lead to total eyesight loss although a good number of people may retain a considerable amount of vision. 

Complications after a LASIK Eye Surgery… Although this is a rare cause of poor night vision, a good number of complaints have been documented over time. The most wide spread grievance is inability to focus and formation of hues around objects. These conditions may exist during the day but are more nagging and perceptible during the night. Some people are more exposed to poor night vision than others as a result of LASIK eye surgeries. The good this is a doctor can examine how prone you’re before conducting the surgery. LASIK eye surgeries are risky and you may have to mull over how to naturally improve vision instead of opting to undergo surgery. 

Treatment of Night Vision Problems

Cataracts; the major cause of diminishing vision at night can be treated. The immediate form of treatment available is undergoing through a cataract surgery whereby the clogged lens is replaced with a manmade lens known as an intraocular lens. Although the eyesight is enhanced dramatically, you may have to wear glasses thereafter.

Strict control of blood sugar can help keep Retinopathy in check. If the Retinopathy is at an advanced stage, a laser is used to destroy minute vessels that might cause harm to your vision. The laser which is referred to as panretinal photocoagulation generally restores vision but it may be lost or reduced ultimately.

If you’re suffering from either Vitamin A or Zinc deficiency, you may consider taking supplement for both of these nutrients or simply eat a diet rich vitamin A and Zinc.

If you detect the complication at its infant stage, the surest, painless and effective way to address the problem is through eyes exercises. However, to make sure that the exercises are effective, you have to perform them regularly preferably three times a day. It may also help understanding the differences between farsightedness and nearsightedness as well.
