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 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.

The affected eye is extremely itchy.

The eyelids get swollen.

It is painful, especially when the surroundings are bright.

A crusty layer may or may not form during sleeping and it can make it difficult to open the eye.

The infection typically affects one eye first and catches on to the other eye within a day because it is highly contagious. People in contact with the affected person are highly susceptible to contracting the infection.

This highly contagious infection is painful and itchy and needs immediate attention. The treatment is the same no matter what the cause. The main causes are:

Bacterial infection (indicated by sticky secretion).

Viral infection (indicated by a watery secretion).

In infants, it can be the cause of a partially opened tear duct.

Sometimes it happens due to an allergic reaction.

A Chemical reaction.

Contact lenses must be removed to prevent further infection. Infected contact lenses must be discarded or disinfected.

Contact with other people must be avoided. Direct physical contact, using the same towel or eye products must be avoided.

Avoiding touching the unaffected eye, it might prevent infection of the second eye.

Using a lukewarm compress can relieve some of the pain.

Using an over-the-counter hydrating eye drop can relieve some of the itchiness and the annoying sensation of having something in the eye.

Conjunctivitis - How Can Ayurveda Help?

Eyeglasses and contact lenses are both used for vision correction. Both of the options have their advantages and disadvantages but a number of factors like lifestyle, comfort and age etc. are important while deciding which one to choose. Here is a list of the fundamental differences between using spectacles and using contact lenses:

1. Distance from the cornea
Lenses are worn directly on the eye and are in constant physical contact with the cornea while glasses are worn over the eyes. Contact lenses may cause infections in the eye because the user has to touch the eye in order to wear them and to take them off.

2. Difference in vision
Since the lenses of spectacles are a little distance away from the eye, vision can be slightly distorted but contact lenses can provide natural and accurate vision. Also, side vision is not improved by glasses as you have to turn your head to see what is beside you. The contacts move around with your eyeballs and the peripheral vision is in focus.

3. Ease of use
Some people find eyeglasses difficult to use because of the constant weight on the face and the obstruction caused by the frames of the glasses. There may also be a constant need to adjust the frames. Often eyeglasses slip down the nose when you sweat or engage in rigorous physical activity. Contact lenses are free from all these hassles - they are not distracting or obstructive and so they are extensively used by dancers and athletes. Spectacles is very uncomfortable to wear during the rains or in humid weather because they fog up.

4. Infections and complications
Contact lenses can get displaced inside the eye and they can be difficult to reposition. They also cause the eyes to itch and water if you wear them for a very long time at a stretch or if tiny dust particles enter your eyes. The use of eyeglasses is far more flexible in this respect - they can be removed in case your eye itches or burns, but regular use of glasses causes dark circles and bags under the eyes.

5. Aesthetic differences
People often prefer contact lenses as they do not change the physical appearance - they help you look natural and you can also use colored lenses to change the color of your eyes. Glasses may look slightly unnatural but some people also prefer them for the fashion quotient.

Lens Vs Specs

The ability to see is one of our greatest powers and it needs to be valued and looked after. Sometimes this involves wearing glasses to improve our vision. Spectacles not only help us see better but also prevent straining and further deterioration of the eye muscles. Here are a few signs to watch out for that will indicate your need for spectacles. Keep in mind however that a comprehensive eye exam is the only way to determine the power required for your spectacles. 

-  Blurred vision
Blurred vision or the inability to focus on something in the distance is one of the first signs or eye deterioration. When it comes to children, watch out for complaints of inability to read the writing on class blackboards.

-  Frequent headaches
Unexplained headaches that come and go could be a sign that you need glasses. These headaches can usually be felt at the end of a long day or after watching television. 

-  Constant squinting
Squinting is a natural way to improve vision. This is because the act of squinting reduces extra light and light scattering thus allowing us to see something clearer. Thus, if you notice yourself squinting more than usual it is time to schedule an eye exam.

-  Difficulty working on a computer
Struggling to read figures and words on a computer screen is usually a sign of poor vision. Try adjusting your screen angle and the distance of the screen from your eyes to see if your vision improves or worsens. 


-  Difficulty adjusting to lights
Sudden increased sensitivity to lights can be a sign of many eye disorders with vision problems being the most common. 


-  Eye strain
Occasional pain in the eyes after a long day or as a result of an allergic reaction is nothing to worry about. However, if this pain persists for a few days, it could be an indication that you need spectacles. 
Deterioration of vision is usually a very gradual process and so you may not realize when it begins. However, the earlier you start wearing corrective glasses to improve your vision the easier it will be to control the deterioration of the eye muscles and you may even be able to rectify your condition completely. So, do not ignore any of these warning signs. Even if you do not have any of these symptoms, it is a good idea to get a thorough eye examination at least once a year.
