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?

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.

Headache - Can Eyestrain Be the Reason Behind it?

While spectacles are a fashion statement for some people, for others they are an uncomfortable necessity. Though contact lenses may be a little more aesthetically pleasing they too can be quite uncomfortable and cannot be worn throughout the day. Thankfully, there is a third way to correct vision. Laser surgery or LASIK, it is a popular refractive procedure that can correct common vision problems, such as nearsightedness, farsightedness and astigmatism. This procedure aims at reshaping the cornea so that light entering the eyes can be focused onto the retina for the person to have a clearer vision. 

Laser surgery is pain-free and quick in most cases. Usually, it does not take more than 15 minutes to correct vision in both eyes. The results of this surgery can be seen in as little as 24 hours. 

The first step of laser surgery to correct vision is to create a thin, circular flap in the cornea. This is then folded back to access the stroma or underlying cornea. An excimer laser is then used to remove some of the corneal tissue. For people suffering from nearsightedness, the cornea is flattened while for people suffering from farsightedness, the cornea is made steeper. In cases of astigmatism, an irregular cornea is smoothened. Once the correct gradient has been achieved the corneal flap is put back into place and the cornea is allowed to heal naturally. There are no stitches or bandages required in a laser eye surgery. You may feel a temporary burning or itching sensation in your eyes immediately after the procedure. It is important not to rub your eyes or place any pressure on them. Your vision may also be cloudy or blurred for the first few hours. A doctor will usually advise you to rest for a few days after the surgery so that your cornea can heal properly. In a few days, your eyesight should stabilize, though, in a few rare cases, it may take a little longer. You should also avoid any form of strenuous exercising for a few days after the surgery. 

Though LASIK surgery has a very high success rate, there are very rare occasions where spectacles may still be needed even after the surgery. Thus LASIK is a choice of treatment for many who seek freedom from glasses.

LASIK - Say No to Boring Glasses! 

As you reach the age of 40, you will likely notice changes in your vision. Perhaps you have difficulty reading a book without glasses, or distinguishing between colours. These changes occur as an effect of ageing. However, nowadays people in their teens are also exposed to a host of eye disorders and vision problems, mostly resulting from eye injuries and visual stress.

The most common disorders of the eye, which affect the age group 19-40, are Refractive errors. The following signs and symptoms characterize such disorders-

  Haziness
  Double vision
  Halos or glares when you are surrounded by bright lights
  Headaches
  Squinting
  Eye strain

What are the Refractive errors?

Refractive errors develop when light cannot focus on the retina (the light-sensitive tissue situated at the rear side of the eye) directly due to the shape of the eye. The change in the cornea s shape, the ageing of the lens, or the length of your eyeball can lead to refractive errors. Most people suffer from one or more of the above conditions.

Type of Refractive Errors:

Following are the most common types of refractive errors-

  Myopia or Nearsightedness - If you have this condition, you will see nearby objects clearly but distant objects will appear blurry. This happens because the light comes to focus right in front of the retina, instead of on the retina.

  Hyperopia or Farsightedness - This condition is just the opposite of myopia. Distant objects are clearly visible but those located close to you appear blurry. However, some people may not observe any problem with their vision at a young age. If you have significant hyperopia, objects at any distance, far or near, can appear blurry.

  Presbyopia - This age-related condition affects your ability to focus on things closely. This happens because as you age, the lens of the eye is unable to change shape to allow the eye to focus on nearby objects clearly.

  Astigmatism - In this condition, the eye cannot focus light onto the retina evenly. As a result, images appear stretched out and blurry.

  Amblyopia or Lazy eye - This vision development disorder begins during early childhood and infancy. In this condition, the eye does not achieve normal visual acuity despite using contact lenses or prescribed glasses. Usually, amblyopia affects only one eye.

Can early diagnosis help treat the problem?

Yes, it can. Your eye care specialist can diagnose refractive errors and detect what exactly is impeding your vision with a comprehensive dilated eye examination. Upon encountering the symptoms mentioned above, one should consult an ophthalmologist at the earliest and get oneself checked.

If the condition is detected early, vision problems due to refractive errors can be treated. The common treatment options include the use of contact lenses, prescription glasses, and surgery (in severe cases).
People with visual problems should also adopt some lifestyle changes to correct their vision - eat more veggies, get adequate sleep and rest, abstain from smoking etc. Additionally, you should get periodic eye check-ups to monitor the condition.

Difficulty In Vision - It Can Be Better If Treated On Time!

Vision is one of our most important senses. Reduced vision that triggers the need for corrective glasses is one of the most common disorders associated with the eyes. Crossed eyes are another such common disorder that affects the eyes. In medical terms it is also known as strabismus. This condition is a result of miscommunication between the brain and the eye muscles that result in misalignment of the eyes. It is largely a hereditary condition and should not be confused with a lazy eye syndrome.

Crossed eyes can cause double vision and disorientation. Your depth perception may also be affected. It also causes eye strains and headaches that affect the quality of your life. This condition is seen mostly in children. If not treated in time, it can continue into the adult years as well. The development of crossed eyes in adults who have not suffered from this condition as children is usually a sign of a serious condition such as a stroke.

Some symptoms characteristic of this condition are:
1. Independent movement of eye balls
2. Tilting the head to a side
3. Squinting
4. Varied points of reflection in each eye
5. Frequently bumping into things as a result of impaired depth perception.

Treatment for this condition can be surgical as well as non surgical. Non surgical treatment aims at strengthening the eye muscles and treating the visual system as a whole. The aim is to not allow the eye to become lazy or amblyopic. Wearing an eye patch over the strong eye and forcing the weak eye to be used is one of the most common form of this treatment. Corrective glasses can also be used to treat this condition in cases where it has been triggered by excessive farsightedness. In some cases, medication may also be injected into the eye to relax the eye muscles.

Surgery to correct this disorder involves correcting vision by strengthening or weakening the eye muscles. To do this, a surgeon must first make a small incision in the outer layer of the eyeball to reach the affected muscles. To strengthen the muscle a small section is removed from the muscle and the remaining part is then rejoined. This makes the muscle shorter and forces the eye to turn towards that side. Alternatively, the doctor may make a partial cut across the muscle to elongate it and let the eye turn further away from it.

Crossed Eyes - How Can It Be Treated

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.
