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.

Astigmatism - Ways They Can Be Diagnosed!

78% of urban youth are in front of the computer screen/ mobile screen for about 12 hours a day. Such extensive strain to the eyes can have long term effects on vision.  Act now to protect your eyes by following these tips-

1) Ensure appropriate glasses or contact lens prescription which is also adequate for computer use. 
2) For prolonged exposure, use glasses to help with contrast, glare, and eye strain when using a computer.
3) Adjust your computer such that your eyes are level with the top of the monitor. This allows you to look slightly down at the screen.
4) Avoid any glare on your computer from windows or lights. Use an anti-glare screen if required.
5) Choose a comfortable, supportive chair. Position it so that your feet are flat on the floor.
6) If your eyes feel dry, blink more often.
7) Every 20 minutes, rest your eyes by looking 20 feet away for 20 seconds. At least every 2 hours, get up and take a 15-minute break.

Protect Your Eyes While Working. 7 best ways.

The most common vision problems are shortsightedness and farsightedness. Shortsightedness is when a person sees close objects clearly while distant objects appear blurry. It is more common than farsightedness and affects about 70% of the Asian population.

When there is a refractive issue, the prescription usually has a plus/minus with it and also a number. A  minus  symbol is used to represent shortsightedness; the greater the number of the glasses, the higher the shortsightedness. High myopia is a more severe form of shortsightedness where the power is -6.0 or higher.

Symptoms: 

As mentioned, the person will be able to see nearby objects but will have difficulty seeing far off objects.

Difficulty reading signs and boards
Squinting
Straining to reduce the strain on the eye
Tired and fatigue due to this eye strain, especially when in constant move like playing sports or travelling
How it happens?

Vision can be explained by a physical process where light passes through a lens and falls on the retina in the posterior portion of the eye where it forms an image. This is then sent to the brain where it is read and interpreted as a particular object. When the lens becomes elongated, the image that is formed is distorted in that it is formed in front of the retina and not on the retina. Though it gradually settles down with adulthood, in most cases, it progresses and requires corrective lenses. The corrective lenses ensure the image falls on the retina and visual perception is improved.

Treatment:

Corrective glasses are the most commonly used measure for nearsightedness. The lenses could be used either as spectacles or as contact lenses.
Laser surgery can also be used to correct the problem. A thin layer of the cornea is removed and the image formation is corrected.
Artificial intraocular lenses are also being used to treat this condition. They work like contact lenses and may need periodic replacement.
The most common technique, especially for high myopia is the use of surgery to correct the problem. This is a one-time correction and is a more durable solution than the earlier mentioned options.
Appropriate calculations are done to identify the lens to be used so that proper vision is restored.
Complications: 

Though not common, retinal detachment and variable postoperative refractive error can occur during the surgery.
It is very important to set realistic expectations with the patient in terms of what to expect before, during, and after surgery. If only one eye is going for repair, the chances of mismatch in vision could be present in the early stages. Being clear about what to expect will help in successful correction.

Myopia or Nearsightedness - How It Can Be Treated?

What crying does to your body

Do you know that every little activity that you perform on a daily basis impacts your body? what you eat, how long you sleep and even every tear you shed affects your body. Most people are aware of how their body reacts to major activities, like exercising, but few are aware of how the body reacts when they cry.

While you are generally concerned with the mental cause and effect of crying, have you thought about what crying does to you physically? tears are not always shed when a person is upset. Tears are a body's way of expressing itself as well as protecting itself. Everything from a happy ending in a movie to a dust particle in the eye can make you tear up.

There are essentially three kinds of tears. Basal tears and reflective tears help keep the eyes lubricated and irritant free respectively. It is the psych tears, which we commonly refer to as crying, that come as emotional responses.

Crying might be a sign of emotional stress and pain but if you are wondering how it harms your body, the answer is that it does not. Crying does not harm one's body physically. In fact it does better than harm to your body, purely physically speaking. Here's how-

- when you cry, your tears help your eyes remain clear.

- it also has anti-bacterial properties that keep your eyes clean.

- your eyes remain properly hydrated thus reducing any kind of irritation. You might feel dehydrated after a while due to the loss of water and salt.

- even the excess manganese in your body gets washed out through tears.

But for some, the act of crying can cause medical complications. It can lead to fits or can cause an acute shortness of breath. For those with severe heart conditions, there can be a cardiac pain. Crying can take a toll on your body if you have certain medical conditions. For most people crying does more good for their body than harm.

Conjunctivitis is a medical condition that is marked by redness in the eyes owing to the inflammation of the conjunctiva, which is the membrane covering the white part of the eye. The condition is further characterized by the discharge of yellowish pus fluid from the corner of the eye. This condition, which is essentially an infection, can occur to people of all age brackets. 

Causes and Symptoms 

Conjunctivitis can be caused due to several reasons namely allergies, irritants, bacterial and viral infections, among others. Apart from the redness in the eye, some other apparent symptoms of conjunctivitis are: 

    Thin and watery discharge in viral conjunctivitis 
    Thick, mucous like discharge ranging from yellow to green in case of bacterial conjunctivitis
    Sticky eyelids
    Increased reactivity to light 
    Blurred or foggy vision
    Nasal discharges 

It is difficult to distinguish between viral, allergic and bacterial conjunctivitis. Different fields of medicine prescribe treatments according to the cause of the condition. Although subtle differences, such as thick and thin discharges can be observed, in Homeopathy the cause is not that important. 

Homeopathic medicines are natural and highly effective. The medications, which are prescribed in Homeopathy can more than manage the discharges, swelling, the sandy sensation and redness in the eyes. Homeopathic medicines are effective when the condition causes the eye to get dry, red, congested and swollen. Bathing the eyes with sterilized salt water is also a popular method of treating the infection. In addition to these, Homeopathic doctors also provide tips to curb the likelihood of further complications. Removing your contact lenses while treatment and cleaning your spectacles on a regular basis, if you wear any, are duly recommended.

Treating Conjunctivitis With Homeopathy

Eye Strain is an umbrella term that denotes a number of symptoms that relate to the extended use of eyes as well as discomfort that may come from excessive smartphone and computer use. This condition may or may not lead to significant eye damage and is usually characterised by blurry vision, headaches and a feeling of dryness in the eye as you blink less which creates less tears. This may happen due to the extended use of the eye when you are following objects on a screen or staring at a screen for too long. So, is eye strain the cause of your headaches? 

Find out more in this article.

Causes: Eye Strain or Asthenopia is caused by concentrating on visually intense tasks like reading from texts that have a fine print, the use of computers and other screens for prolonged periods, and trying to focus on objects in the dark. This can lead to distress of the muscles in this area which can also cause eye strain leading to a variety of symptoms including double imagery and even headaches and mild migraine like conditions.

Eye Muscle Imbalance: When there is eye strain which leads to headaches, it can also give rise to eye muscle imbalance which makes it difficult to concentrate with both eyes at the same time. In such cases, one may need bifocal glasses so as to fix the issue and prevent such debilitating headaches to remain on a persistent basis.

Diagnosis: Digital eye fatigue and ocular eye strain leading to headaches can be diagnosed by a doctor with the help of regular eye examinations. In any case, one should have the eyes checked at least once a year. This is especially important if your job involves sitting in front of the computer screen for prolonged hours.

Symptoms: There are a variety of symptoms of these headaches that are caused by eye strain. Apart from blurry vision which does not allow the patient to see properly and clearly without glasses, it can also cause headaches with symptoms like nausea and sensitivity to light. Retinal or eye migraines do not necessarily have to come with headaches, but the pressure can be painful enough.

Treatment: To begin with, the best form of treatment for headaches born from eye strain includes prevention which can be done by getting plenty of rest and sleep even as we limit the hours spent in front of the screen. One can also lower the resolution of the screen and make it more ambient. Also, the screen should be placed at a considerable distance from the eyes. The doctor can also prescribe glasses and eye drops for better eye lubrication.
