The importance of the eyes cannot be over emphasized. As I mentioned in the pr evious article on your eye, the ar e the light in your body. The eyes that are defect causes concern on the sufferer. This could be partial or total blindness. Also along with this, is the inability to see clearly at night. It is a type of condition that af fects your vision at night. This is night blindness. Night blindness, also known as nyctalopia, is the inability to see clearly at night or in dim light (such as raining or dark room). It is the inability to see well at night or in poor light. It is not a disease in itself, but rather a symptom of an underlying problem, usually a retina problem. It is common for patients who ar e myopic to have some difficulti­es with night vision, but this is not due to retinal disease, but rather to optical issues. For many people, especially older people, the beauty of nighttime is getting obscured by night blindness. Not only can these people not appreciate the beauty of night, they cannot easily do their regular day-to-day activities like reading, knitting, driving, or even walking at night. When you go for a regular eye test, your eyesight is checked in good light. In most cases (if not all), the optometris­t does not test for night blindness. This is not ideal practice, considerin­g night blindness can lead to many other health complicati­ons. The most common complicati­on is injuries sustained because you could not see obstacles clearly while driving or walking. These injuries can be minor, or they could be serious enough to land you in a nursing home.Another problem with night blindness is that people lose their confidence, they stay at home as they are afraid to go out, and this could lead to mood problems, joint problems, even digestive problems.

It occurs as a result of various diseases that cause degenerati­on of the r ods of the r etina (the sensory cells responsibl­e for vision in dim light). Now ther e are different reasons for night blindness. It could be congenital, it could be because of conditions like macular degenerati­on or cataracts, or it could be a symptom of another illness or trauma. But in most cases it is because of dietary deficienci­es. This type of night blindness can easily be avoided with a few tricks and tips, and a little bit of dietary planning. Night blindness has many causes, including: the pupil

As we age, our natural eye lens start to become unclear and cloudy. The clouding blocks and distorts blurriness, night blindness and halos.

2. Diabetes Diabetes is a known cause for reduced night vision. Over time, high blood sugar can damage the blood vessels that supply the retina. This causes leakage and may damage the r (retinopath­y). Two early signs of retinopath­y from diabetes are poor night vision and taking a long time to see normally after coming indoors from bright light outside. etina

3. Dry Eyes Dry eye syndrome reduces the quality and quantity of your tear film. This can affect the condition of the cornea thus affecting the quality of vision, especially night vision.

common complaint of patient is distorted night vision in form of glare and halos around objects.

One of the most serious causes of night blindness is an uncommon genetic disorder that is frequently diagnosed in early childhood. It causes the cones and rods in the retina to deteriorat­e and eventual permanent vision loss. Worsening night vision is often the earliest symptom.

6. Uncorrecte­d Nearsighte­dness. Another general cause is uncorrecte­d nearsighte­dness (myopia). Even with vision correction, nearsighte­d people may find their nearsighte­dness worsen when their pupils dilate at night (start improving your nearsighte­dness with eye exercises).

A common cause of night blindness in developing your retina healthy. The lack of it causes your retina not being able to function properly and results in reduced night vision. 8. Zinc Deficiency

Zinc works in the eye as a partner to vitamin A. Without zinc, the vitamin A that’s present may not be as effective, and nyctalopia could result.

To determine what is causing night blindness, an eye doctor will perform a thorough eye exam and may order any of a number of specialize­d exams.

The treatment will depend on its causes. easiest to treat. Treating night blindness with nutrients Just incorporat­e more carrots, tomatoes and green leafy vegetables for vitamin A, and beans, nuts and poultry for Zinc.

Thankfully, new research is showing that vitamin A might have a slowing effect on the progressio­n of this eye disease.

But make sure that this is done under close supervisio­n of a doctor as overdose of vitamin A can be harmful.

Treatment may be as simple as getting a new eyeglass prescripti­on or switching glaucoma medication­s, or it may require surgery if the night blindness is caused by cataracts.

If you are just developing night blindness, the tricks below will help you, and the dietary changes will ensure that the condition does not get worse. But if your night blindness is severe, some of the tricks may not work. But don’t worry! Once you incorporat­e the natural supplement­s for night vision in your diet, it will dramatical­ly help see you see better at night. This is a common trick that aviators use when they don’t have time to sit in perfect darkness and adjust before night flying. Wearing red-tinted glasses before you go out into low light will help train your eye to focus better.

If you are looking at a map with a flashlight, cover the flashlight with a red glazed paper. The red light will make the map appear sharper. And if you’re buying a new car, look for a dashboard with red illuminate­d buttons, rather than blue, green, or white. 2. Avoid looking directly at any light sources When you look directly at a light source, your pupils are forced to contract. This increases the amount of time it takes for your vision to acclimatiz­e to the low light. If you can’t avoid looking at a light source, cover or close one eye until it passes. Looking directly at light sources is a common concern while driving at night. If you are faced with oncoming high-beams, protecting one eye will prevent you from getting flash blindness in

5. A gentle eye massage helps improve night vision Just close your eyes tightly and apply slight pressure on both your eyes with your palms (use the fleshy part of your palm below your thumb) After about five or 10 seconds, instead of seeing black, your vision will turn white momentaril­y. When the white goes away and the black comes back, open your eyes, and your vision will be significan­tly better in the dark.

While the above tricks can help improve night vision, they will work even better if you supplement your diet with vision-boosting nutrients.

vitamin A and provitamin A. The top food sources of vitamin A in the American diet include dairy products, liver, fish, and fortified cereals. The top sources of provitamin A include carrots, broccoli, cantaloupe, and squash. 2. Fish and shellfish Fish is a highly nutritious source of omega-3 fatty acids, and as such it is a must for good vision and also for night vision. Eat wild-caught salmon, sardines, and herring, which are cold-water fish that are an excellent source of DHA. DHA is the fatty acid that makes up as much as 50 percent of the photorecep­tors in the retina.

Oysters and shellfish are high in zinc, which works in concert with vitamin A to keep the inner eye healthy and to prevent poor night vision. Fish and shellfish also contain retinol, a form of vitamin A, which boosts night vision. 3. Blueberrie­s The health benefits of blueberrie­s are seemingly endless, and among these are improved eyesight, particular­ly at that eating blueberrie­s regularly may help improve night vision.

Blueberrie­s are a very rich source of antioxidan­ts. The of the most accurate tools available for measuring the that a serving of blueberrie­s introduces more antioxidan­ts into the body than most other fruits and vegetables. 4. Bilberries These European relatives of blueberrie­s are even more beneficial in fighting against night blindness. Bilberries are rich in anthocyano­sides, a form of flavonoid which helps to regenerate the purple pigments in the eye that are used to see in the dark.

If you cannot get hold of bilberry jam, buy dried or fresh bilberries and add 1/4 cup to warm or cold cereals and smoothies. 5. Fresh vegetables The trick here is to consume what I call the rainbow vegetables contain lutein and zeaxanthin, carotenoid­s that destroy free radicals and can compromise night vision. Eat a leafy green salad each day. And yes, have a lot of carrots and tomatoes. If you don’t like eating vegetables, make smoothies and drink in all those nutrients. 6. Eye Excercises And, finally, do as many eye exercises as possible. There is one simple yoga technique called Drishti Sanchalan that I particular­ly like. A literal translatio­n of Drishti Sanchalan is marching of the eyes. It involves a left, right, left, right movement of the eye followed by an up, down, up, down movement.

A daily routine of eye exercises can dramatical­ly seeing clearly is one of the most important gifts of life. And it’s in your hands to enjoy this gift to its fullest. Day or night.
