People may have weak eyes due to a variety of reasons. Astigmatism happens to be one of those reasons. When one is affected by astigmatism, it results in blurry vision. The eye has a part called the cornea, which is the outermost layer of the eye and is responsible for allowing light to enter. When the cornea is not shaped as it should be, it leads to astigmatism.

However, this is not the only condition under which it can occur. In fact, there are two different types of astigmatism. One is corneal astigmatism which is the result of an odd-shaped cornea. The other is lenticular astigmatism, which occurs when the lens has an incorrect shape. More often than not, people are born with astigmatism. However, there are chances of developing this eye disorder after an eye injury or after an eye disease.

How to diagnose?
There are a few ways in which astigmatism can be diagnosed. 

One of the most popular methods is the visual acuity test. This measures the distance at which a letter is read clearly, as compared to what it should be. 
Another way is by refraction. By placing lenses in front of the eyes, the way they focus light is measured. 
The third way by which astigmatism can be detected is by keratometry, also known as topography. Light is focused on the cornea and the reflection is measured to find the curvature of that area.
Treatment options
The easiest way to go about treating astigmatism is by using corrective lenses. This is usually the method of treatment for people whose astigmatism is not that bad. The lenses could either be a part of spectacles or used as contact lenses. The good part about contact lenses is that the field of view is wider.

Orthokeratology (Ortho-k) works to improve astigmatism by using lenses as well. However, the lenses are of the hard variety. These lenses are useful for corneal astigmatism patients as they reshape the eye. Usually, they are worn while sleeping and most people can have normal vision the next day. However, if one stops using them, the eye goes back to its original state. So, they are not a permanent solution.

Surgery, however, can be a permanent solution to astigmatism. LASIK and PRK are two of the most popular types. RK is also popular, but to a lesser extent. It is good to remember that the risks of surgery should be discussed with a doctor prior to undergoing one.

Natural Remedies For Better Eyesight

An eye allergy or allergic conjunctivitis is a condition that strikes when certain substances irritate the eyes, which can cause a reaction. This reaction has varied symptoms starting from inflammation to watering and even redness and an itching sensation. So how can you tell if you have an eye allergy? this article will tell you all you need to know!

Causes: to begin with, this is an immune response that happens when the eye comes in contact with substances like dirt, grime, pollutants, pollen, nettle, pet hair, smoke, mold and more, which may cause irritation. These are typically known as allergens. The immune system takes these allergens to be invaders and begins attacking the same by releasing chemicals that cause these allergic reactions. Also, an eye allergy may be a symptom or outcome of other conditions like asthma, hay fever, or even eczema.

Symptoms: the eye usually bears a pink or red appearance when the patient is suffering from an eye allergy. Also, watery eyes are a common sight during this condition while scaling around the eyes may also take place. Further, itching and burning sensation may be felt by the patient and swelling or puffiness can be seen. The symptoms may afflict one or both eyes. The patient may also have a runny nose or stuffy nose as well as nasal congestion.

Difference between eye allergy and pink eye: conjunctivitis or pink eye is usually caused due to bacteria or a virus that spreads infection in the eye. But eye allergy is caused due to a response of the immune system that leads to an allergic reaction. While the pink eye may be a contagious condition, an eye allergy is not.

Diagnosis: the diagnosis of an eye allergy will be done with the help of various tests conducted by an ophthalmologist. The skin prick test will help in introducing allergens to find out if the spot gets raised or suffers from inflammation. Also, the doctor will check for other ailments like asthma and eczema.

Treatment: there are varied methods of treating this condition. To begin with, the doctor may prescribe medication like decongestants and antihistamines as well as steroids for more severe and persistent cases. Also, injections may be prescribed in order to do away with the allergic reaction and eye drops containing olopatadine hydrochloride may also be used.

Home remedies: staying away from allergens and using a warm and clean washcloth over the eyes, for a few minutes every day, may help in relieving the painful symptoms of the condition.

Do not forget to consult your doctor before you try any natural or home based remedies.

Are You Suffering From Eye Allergy?

Cataract can be defined as the clouding of the natural lenses in the eyes. This is caused by the clumping of protein in the eye lens. Cataract is a common eye disorder and the leading cause of loss of vision in people who are past their fortieth birthday. Cataract can occur in one or both eyes. When diagnosed properly, cataract can be treated with surgery to prevent blindness.

Depending on where and how they develop, there are many types of cataract. The most common amongst these are:

1.        Subcapsular cataract

These occur at the back of the eye lens. Diabetic patients are very susceptible to this kind of cataract.

2.        Nuclear cataract

Yellowish-brown cataract that form in the center of the lens are called nuclear cataract. This is usually seen in cataract caused by ageing.

3.        Cortical cataract

Cataract in the lens cortex are known as cortical cataract. These are wedge shaped and whitish in color. Spokes protruding out of these opaque wedges can be seen moving towards the center of the eye.

4.        Congenital cataract

Though they are not common, babies can also have cataract. Cataract formed at birth or within the first year of a baby's birth are known as congenital cataract.

5.        Secondary cataract

Cataract is one of the known side effects of diabetes and glaucoma. Some steroids and medicines are also linked to cataract.

6.        Traumatic cataract

If your vision becomes cloudy years after an eye injury, it could be a traumatic cataract. It can take several years for this to happen.

7.        Radiation cataract

Exposure to radiation can also lead to cataract. This is seen sometimes in patients who have undergone radiation therapy to fight diseases like cancer.

Though the type of cataract might differ from person to person, the symptoms are usually the same. Some of the common symptoms of cataract are:

1. Blurred vision
2. Reduced night vision
3. Increased sensitivity to light and glare
4. Seeing halos around lights
5. Colors appearing faded
6. Double vision

A reading test is the first step towards diagnosing cataracts. This is followed by tests to measure the eye pressure. Your doctor will also need to dilate the pupil to check the condition of the optic nerves and retina.

Surgery is the safest way to remove a cataract. Surgery is usually recommended when cataract begin inhibiting your daily life such as preventing you from driving, interfering with reading etc.
 
In most cases, this can be done as an outpatient procedure. The earlier it is diagnosed, the easier it is to treat. Hence, if you notice any of the symptoms mentioned above, get your eyes checked at once. The surgery is a day-care surgery only, so a person can go home the same day.

Is Your Vision Clouded? It Could Be Cataracts

5 myths about eye health and the real facts behind them

Your eyes are an important part of your health. There are many things you can do to keep them healthy and make sure you are seeing your best. However, there are a number of myths regarding what you should do and what you shouldn't do when it comes to maintaining good eye health.

Here are 5 of those myths busted:

Myth #1: reading in dim light and sitting too close to the tv hurts your eyes

Fact: sitting too close to the tv, you may feel eye strain or get a headache from reading in the dark, but it will not weaken your eyes. It fatigues your eyes but does not harm your eye health in any way.

Myth #2: eating carrots will improve your vision

Fact: carrots are rich in vitamin a, a nutrient essential for good vision. But eating carrots will only provide a small amount of vitamin a. To get the optimum amount, you need to include other sources of vitamin a in your diet as well, some of which are milk, cheese, egg yolk and liver. Spinach is best for eye health. It has lutein and zeaxanthin, both of which can help prevent cataracts.

Myth #3: if you wear glasses or contacts for a continuous period, your eyes will weaken

Fact: your eyes will not grow weaker by using corrective lenses. The prescription may change over time due to aging or absence of disease but it has nothing to do with your current prescription. Some children have correctable eye problems that do require glasses to improve the condition.

Myth #4: when you get something in your eye, rub it out

Fact: this is not true for everything that gets in your eyes. If any particle falls in your eyes dust it off. But if it is sand and small debris that gets in your eye, don't touch it. Use an eye wash for flushing it out. If an object gets stuck in your eye, don't remove it or rub your eye constantly. Visit a doctor at the earliest because some serious injuries may seem minor at first.

Myth #5: dark sunglasses can protect your eyes from the sun

Fact: the color of sunglass does not ensure eye protection. Look for sunglasses that block both uva and UVB rays. Exposure to the UV-rays of sunlight can have cumulative effects on your eyes. It increases your risk for cataracts, solar retinitis, and age-related vision loss. Even if your contacts have UV protection, wear sunglasses that block 100% of uva and UVB rays for full protection.
