Night blindness is also called nyctalopia.It's a type of vision impairment. People with night blindness experience poor vision at night or in dimly lit environments. It is not a disease in itself, but rather a symptom of an underlying problem, usually a retina problem.

What Causes Night Blindness?
A number of eye conditions can cause night blindness, including:
1. Nearsightedness or blurred vision when looking at faraway objects.
2. Cataracts or clouding of the eye's lens.
3. Retinitis pigmentosa, which occurs when dark pigment collects in your retina and creates tunnel vision.
4. Vitamin A Deficiency
5. Zinc Deficiency
6. Dry Eyes
7. Diabetes

Are the Symptoms of Night Blindness?
The sole symptom of night blindness is difficulty seeing in the dark. You're more likely to experience night blindness when your eyes transition from a bright environment to an area of low light, such as when you leave a sunny sidewalk to enter a dimly lit restaurant. You're likely to experience poor vision when driving due to the intermittent brightness of headlights and streetlights on the road.

How can I Prevent Night Blindness?
You can't prevent night blindness that's the result of birth defects or genetic conditions, such as Usher syndrome. You can, however, properly monitor your blood sugar level and eat a balanced diet to make night blindness less likely. 

Orange colored foods are excellent sources of vitamin A, including:
1. Cantaloupes
2. Sweet potatoes
3. Carrots
4. Pumpkins
5. Butternut squash
6. Mangoes

What are the Treatment Options for Night Blindness?
The treatment will depend on its causes.
1. Nutrient deficiency (Vitamin A and Zinc) is the easiest to treat. 
2. If the cause is cataract, you can go for cataract surgery to remove the clouded lens and replace it with artificial intraocular lens. Vision is usually dramatically improved after surgery. 
3. For dry eye syndrome, lubricate your eyes with artificial tear drops as they provide instant relief. Just make sure that they are without preservatives. 
4. Diabetic retinopathy can be prevented with tight control over blood sugar, active lifestyle and good dietary habits.
5. As for retinitis pigmentosa, unfortunately there are no treatments available. Thankfully, new research is showing that vitamin A might have a slowing effect on the progression of this eye disease.

Night Blindness: Causes and Symptoms

4 tips for a great eyesight

An important organ of the body, eyes must never be taken for granted and need to be protected at all times. In addition to protecting them, you also need to improve as well as maintain their overall health.

Here are some of the ways of keeping your vision in top form:

1. Eat for good eye vision

To have healthy eyes and consequently good vision, you need to have foods that keep them in good health. Nutrients like Zinc, vitamins C and E, and Omega-3 Fatty Acids can help to fend off age-related sight problems such as cataracts or macular degeneration (a condition characterized by the deterioration of the middle portion of the retina). Foods like eggs, nuts, green leafy vegetables, oranges and citrus fruits are what you need to have to get good eye health. 

2. Kick the Smoke habit

Smoking can adversely affect your eye health and can make you prone to eye conditions like cataracts, macular degeneration and damage of optic nerve (a nerve that transmits impulses from the eyes to the brain). By kicking this habit, you end up saving your eyes from irreversible damage.

3. Use sunglasses

Exposure to the Sun's ultraviolet rays for a long period of time can make you prone to common eye problems including cataracts. To protect them from the Sun's harmful rays, you need to use sunglasses that block 99-100% of Ultraviolet A (UVA) and Ultraviolet B (UVB) rays.

4. Go for a regular eye checkup

Going for regular eye examinations can help in protecting your vision and ensure you see clearly. Eye examinations are important to help you find eye problems like glaucoma (a condition wherein the optic nerve is damaged, resulting in vision loss). A comprehensive eye examination can help in identifying problems like nearsightedness, farsightedness or astigmatism (an eye defect that occurs to a deviated spherical curvature).




4 Tips for a Great Eyesight

The eye is a complex organ. It is made up of a number of different parts which together build a sense of image. Retina is a very significant part of the eye. It is this part of the eye that helps it project the image. The object image is ultimately created on this part of the eye. But it is also a very sensitive and delicate organ. There are many abnormalities that may affect the retina. Central Serous Retinopathy is one such abnormality.

This medical condition of the eye is precipitated when there is a buildup of fluid behind the retina. This leads to the detachment of the retina. The patient may experience gradual or even sudden loss of vision as the central retina gets detached.

The Retina and its Structure

The retina is a very important part of the eyes. It is a membranous structure where vision takes shape and is composed of several layers. It contains special photoreceptor cells that help in identifying color, vision, etc. There are different cells that help in central as well as peripheral vision. The central region of the retina is also known as macula. Retinal Detachment is a disorder of retina that can turn people blind or low in vision. Medical intervention is necessary to regain lost vision.

Symptoms of Central Serous Retinopathy

Patients need to be aware of the symptoms lest they should be caught completely unaware of it.

Objects may appear farther away than usual.

White portions of images may appear dull and lines may appear crooked.

Patients may experience blurry vision in the initial stages.

However, it does not always a precipitate symptom. If fluid buildup is not affecting the central vision area, the patient may not experience any deterioration in central vision. This is a perception that the central part is responsible for the central vision. He or she may experience a clear central vision, although there is a fluid buildup. Nevertheless, it may eventually push the central part and detach the retina resulting in Central Serous Retinopathy. Patients may experience a darkening or blurring of their central vision. This is usually limited to one eye. However, one may experience such problems in both eyes at different stages of life.

Risk factors

Though the contributory factors are not well known, it is thought that stressful lifestyles and some medicines can contribute to such ailments.

Treatment

Treatment may not always be required in all cases. Doctors may just ensure that built-up fluid is draining out. However, if fluid is not draining out, medical intervention is necessary doctors may go for treatments like photodynamic therapy, thermal laser treatment, or medications. Doctors may also recommend stopping steroids and bringing in lifestyle changes.

Conclusion:

People who notice any changes in their vision or experience pain or blurry vision should consult an Ophthalmologist as soon as possible. If a person is already suffering from any eye disease and experiences such symptoms, he/she should immediately seek medical attention without waiting for his/her next appointment.

In some cases, the fluid dissolves itself with no further medical treatment. However, if it does not, a variety of medicines and medical treatments are available.

Eye Allergies - 5 Homeopathic Remedies For It

Blurred vision is most often a sign that you need corrective spectacles for near sightedness, far sightedness or astigmatism but it could also be a sign of a bigger problem including eye diseases or neurological problems. Blurred vision involves the loss of sharpness of vision and objects appearing hazy and out of focus. It can affect one eye or both eyes simultaneously.

Whatever be your age, it is a good idea to consult a doctor as you begin to experience a blurred vision. To measure the extent of your vision problem, a doctor will do a comprehensive eye examination including spatial contrast sensitivity and a standard eye chart test. Some of the factors that trigger blurred vision are:

1. Myopia or nearsightedness
2. Hypermetropia or farsightedness
3. Astigmatism caused by an irregularly shaped cornea
4. Presbyopia - the diminished ability to focus on objects due to the hardening of the lens in the eye
5. Dry eyes or the lack of lubrication on the surface of the eyes
6. Hormonal changes during pregnancy
7. Migraine headaches
8. Temporary floaters in the eye formed by the liquefying of the gel in the eyes
9. After effects of lasik surgery
10. Eye drops or medication
11. Overuse of contact lenses
12. Diabetes

Blurred vision can also be a symptom of a serious condition such as cataract, glaucoma, macular degeneration, diabetic retinopathy and cardiovascular diseases.

Treatment for blurred vision depends on the factors triggering it. Wearing corrective glasses can cure blurred vision caused by myopia, hypermetropia and astigmatism. These conditions can also be treated by lasik surgery. For blurred vision related to diabetes, check your blood sugar and get it into its optimal range.

Exercises for the eye muscles can also help sharpen vision and lower the rate of eye muscle degeneration. Some of these exercises are:

1. Alternately focus on an object close to you and another far from you for ten seconds each.
2. Blink your eyes and hold for two seconds
3. Roll your eyes clockwise and anticlockwise. Repeat 15-20 times.
4. Rub your palms together to generate heat and place over your eyes to relax them.

A healthy diet with plenty of vitamin a can help keep your eyes healthy and prevent blurring of vision. Wearing sunglasses can also protect your eyes from harmful uv radiation and lower their rate of wear and tear. Lastly avoid reading in moving vehicles and holding a book too close to your face.
