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.

Is Your Vision Blurry? What Should You Do?

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

The quality and sharpness of vision are generally measured with a Snellen chart. The Snellen chart shows letters of logically smaller size. Perfect vision is 20/20. This implies the patient or subject sees the same line of letters at twenty feet that a typical individual sees at twenty feet.

Here are a few doctor recommended tips that can be followed in order to achieve a perfect vision. These are as follows:

1. Eat right for good vision
Taking good care of your eyes begins with the food that you eat. Foods, for example, fatty acids, lutein, zinc and vitamins C and E may avert age related vision and eyesight problems, for example, macular degeneration and cataract as shown by certain studies. Eating these foods daily can lead to healthy eyesight. Following are some of the nutrients that can help us do so:

    Green vegetables, for example, spinach, kale, and collards
    Salmon and fish
    Eggs, nuts, beans, and other non-meat protein sources
    Oranges and different citrus natural products or juices
    Shellfish and pork

2. Quit smoking
Smoking makes you more inclined to get cataract, optic nerve damage and macular degeneration. The more times you attempt to stop smoking, the more probable you are to succeed.

3. Wear shades
The right sort of shades will shield your eyes from the sun's bright (UV) beams. An excess of UV exposure makes you more inclined to get cataracts and macular degeneration. Pick shades that piece ninety nine to hundred percent of both UVA and UVB beams. Wraparound lenses shield your eyes from the side. Spellbound lenses diminish the glare when driving. Some of the contact lenses come with UV protection as well. It is still a smart thought to wear shades for more protection, however.

4. Turn away From the Computer Screen
Gazing at a computer screen for a really long time can bring about eye strain, foggy vision, trouble focusing at a distance, dry eyes. The muscles around the eyes can start getting weak and painful if given too much strain. Turn down the screen brightness. You need to at present have the capacity to see, however, you should not feel like you are gazing at a very bright light. In case you are reading from the computer, use the zoom capacity to make the content bigger.

5. Pencil exercise
Take a pencil, and place it some place in the centre. Draw a letter, number or dot in on any side of the pencil. For this activity, you will concentrate on the pencil and the spot as you move it toward and far from your eyes. Pencil push-ups are rumoured to correct twofold vision and crossed eyes, yet it cannot hurt to attempt them for different issues since it is free, easy, and just includes focusing and refocusing your eyes. 

How to Have the Perfect Vision? Doctor Recommended Tips

LASIK stands for Laser In-situ Keratomileusis. This is a common eye surgery that helps in correcting vision problems. During this procedure, the cornea of the eye is cut across by a medical expert to raise the tissues and reshape them to correct vision. LASIK is suitable for patients who have shortsightedness, long sightedness or who suffer from astigmatism.

Here are the 5 benefits that a LASIK surgery offers:

1. Improved vision

A study reveals that 95% of the people who underwent this surgery achieved uncorrected visual acuity of 20/40 and 85% of the people achieved 20/20 vision. This procedure ensures that a patient achieves enhanced vision.

2. Quick results and recovery

This surgery enables you to return to your normal schedule immediately the day after the surgery. You can have clear and improved vision within a day.

3. Long- lasting outcomes

A minimum timeframe of 3 months is required for the eyes to adjust, after which LASIK results are permanently noticeable in a patient. No follow up procedures are required unless something wrong went with the surgery. The patient will continue to have improved vision unless there is any normal loss due to illness or aging.

4. No need of glasses

You no longer require glasses as your vision turns to normal post-LASIK surgery.

5. Goodbye contact lenses

LASIK surgery will help eliminate the need for contacts. You will be able to avoid all the problems pertaining to wearing a contact lens, including lens solution.

5 Benefits of Lasik Surgery

Cataract is clouding of clear natural lens present inside the eye, this is a major cause of decreased vision in elderly. Cataracts can occur in one or both eyes, usually developing very slowly. Things look blurry, hazy, less colourful and less sharp with cataract. 

Most cataracts are related to ageing, however many other factors can either increase the rate of formation or cause cataract formation. 

Causes of Cataract Formation-

Ageing: Most common cause. As the proteins present in the lens of the eye degenerates over the years ( just like any other organ) cataract is formed. If you are having Diabetes or hypertension, the rate of formation gets accelerated.

Radiation: Prolonged exposure to ultraviolet rays, especially UV-B rays, results in cataract in your eyes. Wearing sunglasses in the daytime helps in slowing down the process of cataract.

Genes: Many genetic disorders can result in congenital cataract ( cataracts present since birth) or early formation. Like in Lowe syndrome or Down's syndrome. 

Lifestyle Choices: Cigarette smoking, long hours of sun exposure regularly, antioxidant, poor diet etc. are responsible for the onset of cataract.

How To Detect Cataract?

Certain signs and symptoms suggest the existence of cataract in the eye. Depending on the type and level of cataract, problems in vision occurs. The main symptom is foggy cloudy vision as if seeing through a dirty glass window. 

Other Symptoms are- 

inability to see clearly in bright light (during the day) which becomes better in dim light ( evening and night) and vice versa. 
watery, tired eyes - mild pain in and around eyes. 
yellow tinge in vision 
Halos around light bulbs or bright light. 
If you are experiencing above symptoms and having problems in viewing things clearly, visit an ophthalmologist and get your eyes checked.

Foggy and Cloudy Vision - A Sign Of Cataract?

A person is said to have great vision more in the metaphorical way than in the literal sense. However, having both is just so important, especially as the ability to see reduces as a person gets older. Old age comes with its own set of problems, and vision loss is one of them. If kept in check from an early age, however, vision loss can be deferred indefinitely.

While a person's eyesight is likely to deteriorate over the course of his life, there is a lot which can be done in an effort to make sure that this is not the case. To start with, it makes good sense to be regular with eye check-ups. After a person attains the age of sixty, he or she should have a doctor take a look at his or her eyes on a yearly basis. There is no point trying to conserve eye sight if a person is too late in taking corrective action. By paying a visit to the ophthalmologist, a person will get to know the exact problem that he is suffering from.

A good diet which is rich in the nutrients which improve a person's eye sight does go a very long way in the long run. A person should make sure that is diverse enough to take care of the needs of a person and should include grapefruit, strawberries as well as berries and nuts.

One of the main things which can be done in order to preserve the health of a person's eyes until he or she reaches an advanced age is to stop smoking in all forms. As a matter of fact, tobacco leads to cyanide entering the blood stream and this does a lot of damage to the eyes. In fact, quite a few irreversible conditions of the eye are caused due to this.

Exercise is said to be good for a person at any age for a variety of reasons and it is really good for even the eyes, though the link may not be immediately so clear. It reduces the risk of age related degeneration by up to 70 per cent!

What is really interesting about a person's eyes is that they can be signs of trouble in other parts of the body. For example, if a person has blurry vision, they should get checked for diabetes. Also, eyes which do not produce enough natural lubrication can show a risk of rheumatoid arthritis and perhaps even thyroid disease.

All in all, a person's eyesight is so crucial to his or her overall health and wellbeing. We have only one pair of eyes, so we might as well take care of them!
