A common headache can have a number of reasons behind it, such as defective vision, hetrophoria or convergence deficiency, etc. Now, the question arises as to how they can cause headache. Read on to know more...

Q. Why should defective vision cause headache?

To attain a perfect vision, eyes with defective vision have to make sustained extra efforts, which results in headache. Even if the refractive error is very small, it can be the cause of headache. More prolonged the working and smaller the print, higher the incidence of headache.

Q. Can this occur at all ages?

Yes, it can occur at all ages. However, with age, the resistance decreases and hence elderly people are more prone to get headache. More the use of computer, mobiles, TV or prolonged studies precipitates headache

Q What is Hetrophoria?

Normally, both eyes always remain parallel, but in some cases, eyes have slight tendency to develop minor squint, may be convergent or divergent. This is called Hetrophoria or Latent squint. Such patients have to take extra strain to keep the eyes straight

Q. What is convergence deficiency?

For reading, both eyes have to converge and if there is weakness of convergence, extra strain has to be put on the eyes, which cause headache.

Q. What is the ideal method of refraction in young patients, I,e below 40 years?

Ideal method is to dilate the pupil with Tropicasyl plus drops. This has the advantage that the doctor can see the retina and Optic Disc. This is important to exclude any involvement of brain as the cause of headache. It also relaxes accommodation and hence provides correct refraction. In cases of Hypermetropia, it is extremely essential to dilate the pupil.

Q. What is the role of Autorefractmeter (a computer) in refraction?

It is a very important instrument to provide correct refraction, but it cannot be totally relied upon. Some opticians rely on it and give wrong numbers.

Q. What is acceptance Test?

You have refracted the eyes with Autorefractmeter or Streak Retinoscope but exact power is what a patient accepts. This is very important.

Q. What is astigmatism?

There is a difference in refraction in different meridians and it is important that a cylinder number is prescribed in correct axis. This is a difficult task and needs lot of experience.

Q. Is it important to correct astigmatism?

To relieve headache and strain on the eyes, it is very important that exact cylinder is prescribed.

Q. What is the role of exact centring of Optical Lenses?

You may give correct number, but if the centre of the Optical lenses and cornea do not coincide, satisfactory results are not obtained. To dispense correct lenses is a big art and the Optician must be qualified and well experienced.

Q. Does the quality of lens affect the visual comfort?

Yes, it is important that quality of lenses should be good, preferable fibre lenses which are Ant reflect coated. Crizal coating with capability to block the UV rays are very popular.

Conclusion: Refractive errors are important cause of headache and needs proper examination of the eyes, preferably after dilating the pupil. Astigmatic error even if too small may be the cause of headache. Spectacle dispensing is an art and a patient must select proper optician. Spectacles if advised for constant use must be used constantly to get full relief.

Defective Vision - Can it be a Cause of Your Headache?

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?

Visual impairment is a decreased ability to see to a degree that causes disabilities or problems, not fixable by usual means, such as glasses. Loss of vision may be acquired and develop suddenly. It may affect one or both your eyes.

What Causes Loss of Vision/Disability?

Loss of vision and disability can result from the following  

Clouding of normally transparent eye structures

Abnormalities in the retina

Abnormalities in the nerves carrying visual signals to the brain from the eyes

Changes in vision may also occur due to conditions like glaucoma, macular degeneration and diabetic retinopathy. 

Can Psychological Rehabilitation Help Manage Visual Impairment?

Vision loss and disability often interfere with one s functional ability in everyday tasks. Sometimes, the disability may be so devastating that it affects a person s mental health and behaviour. Psychological Rehabilitation is designed to help such visually impaired people deal with disability or impairment. 

Psychological rehabilitation involves a wide range of methods that aims to restore functioning after loss of vision, just as physiotherapy restores functioning after an injury or stroke. The program allows patients to continue living independently and maintain their quality of life despite vision loss. 

Complete or partial loss of vision can jeopardize one s career   you may not be able to continue with your job due to the disability.  Many people suffer psychological and physical challenges, which force them to escape the outside world. Psychological rehabilitation helps in the following ways  

Helps individual understand and accept the disability, and find ways to cope with it

Motivates them in to keep trying

Cope with the pain and depression

Overcome feelings of fear or despair

Prevents the person from sinking into a state of self-pity, which may hinder recovery

Rehabilitation Psychology adopts a holistic and expansive approach to treat visual impairment. 




Loss of Vision & Disability - How Can Psychological Rehabilitation Help?

Eye allergy or allergic conjunctivitis is an adverse immune response of the body that occurs when it comes across an irritating substance or allergens like smoke, dust or pollen. The body assumes these to be harmful substances and releases chemicals called histamine to fight against them.

Symptoms of an eye allergy-

Allergy in the eyes causes the occurrence of certain symptoms-

  Itching in the eyes

  The sensation of burning in the eyes

  Redness

  Watery discharge

  Swollen eyelids

  Light sensitive

What triggers it?

An eye allergy is usually triggered by the following components-

  Pollen

  Dander

  Dust Mites

  Mould

  Pet Dander

  Exhaust from vehicles

What to do if you suffer from eye allergy-

  Consult an eye specialist or allergist - It is important to consult a physician since the symptoms may pertain to other allergies like asthma or eczema that have different treatment.

  Take proper medication - Take the prescribed eye drops, oral histamines or decongestants to alleviate the symptoms.

  Avoid the allergen - It is difficult to do so if the allergies are seasonal, that means if the eye allergies always occur during specific seasons of the year. If they are not seasonal, you can avoid the allergens if you

Keep the doors and windows closed at home and while riding the car
Take a shower or change your clothes after coming back home from outside
Wear an allergy-relief mask while outside to filter the smoke, dust, etc.
Wear glasses to protect eyes from the allergens
Wash hands after petting any animal
Use a dehumidifier to protect against mould
  Take allergy shots - These are good precautionary measures for seasonal allergies. These increase the tolerance for the irritants. Similarly some eyedrops can be given to decrease the frequency, severity and intensity of allergy episodes.

  Natural remedies - If nothing else works you can use a cold compress to relieve the itchy eyes. Eat walnuts, fish oil and flaxseed oil that contain Omega- 3 fatty acids to reduce inflammatory substances in the body.

What not to do if you are having an eye allergy-

  Avoid rubbing your eyes; that will further irritate your eyes and damaged the eye surface

  Do not keep your indoor surroundings dirty and dusty

  Do not dry-sweep the floors

  Do not pet any animal if you are allergic to animal dander

There is no permanent cure for eye allergies yet but the proper treatment and precautions can help to reduce many of the symptoms. Over-the-counter medications may work out for some people but others may require severe treatment. Remember in spite of prophylactic or therapeutic treatment if u are exposed to a high load of allergens, you will develop symptoms of allergies but they will be milder than if u had no prophylaxis.

Eye Allergies - What To Do & What Not To Do?

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.

4 effective tips for improving your eyesight

You'd be shocked to know that 1/3rd of the blind people of the world are Indians, which amounts to about 15 million people in India alone. Moreover, the risk of cataract is also high in India, with about 3 million people developing this condition, annually. Even the number of people with power in their eyes in India has gone up considerably. Thus, proper eye care is the need of the hour.

Here are some useful tips to maintain your eyesight, while improving your overall eye health.

1. Ensure that your eyes remain hydrated
You can do so by drinking the standard 8-10 glasses of water a day. Moreover, opting for a pair of sunglasses having a UV filter also proves to be useful in this regard. The reason behind is that sunglasses prevent the wind from robbing the moisture away from your eyes. Alternatively, you can ask an optometrist to prescribe a simple saline solution to hydrate your eyes and give them a soothing feel.

2. Don't keep looking at the computer screen continuously
Staring at the computer screen for a long time at a stretch can affect your eyes negatively. So, implement the 20/20/20 rule into your daily routine. According to this rule, you should remove your gaze from the computer screen every 20 minutes and then direct your vision towards an object kept at a distance of 20 feet for 20 seconds. This break helps your eyes to relax and refocus, consequently avoiding the occurrence of blurry vision.

3. Give your body a balanced diet and correct amount of sleep
Ensure that your daily diet contains green, leafy vegetables and fruits and food rich in antioxidants. These food products help in improving your vision to a large extent. Moreover, sleep for around eight hours every night to prevent eyestrain.

4. Make it a daily habit to perform eye exercises
The most effective technique to naturally improve your eyesight is performing eye exercises. Regular eye exercises not only enhance your vision but also give strength to your eyes.

Here's a simple exercise you can try. This works by applying heat to your eyes in order to relax them. For this, you can rub your palms together till they become warm and then place them on your eyes. Let your palms remain there for 10 seconds and then open your eyes.

It is also very important that you take care of your existing health problems like diabetes, hypertension, neurological problems or allergies and be regular with exercising such that it keeps your body fit and does not bear any impact on other organs like eyes.
