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.

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

Night blindness is also called nyctalopia.It's a type of vision impairment. People with night blindness experience poor vision at night or in dimly lit environments. It is not a disease in itself, but rather a symptom of an underlying problem, usually a retina problem.

What Causes Night Blindness?
A number of eye conditions can cause night blindness, including:
1. Nearsightedness or blurred vision when looking at faraway objects.
2. Cataracts or clouding of the eye's lens.
3. Retinitis pigmentosa, which occurs when dark pigment collects in your retina and creates tunnel vision.
4. Vitamin A Deficiency
5. Zinc Deficiency
6. Dry Eyes
7. Diabetes

Are the Symptoms of Night Blindness?
The sole symptom of night blindness is difficulty seeing in the dark. You're more likely to experience night blindness when your eyes transition from a bright environment to an area of low light, such as when you leave a sunny sidewalk to enter a dimly lit restaurant. You're likely to experience poor vision when driving due to the intermittent brightness of headlights and streetlights on the road.

How can I Prevent Night Blindness?
You can't prevent night blindness that's the result of birth defects or genetic conditions, such as Usher syndrome. You can, however, properly monitor your blood sugar level and eat a balanced diet to make night blindness less likely. 

Orange colored foods are excellent sources of vitamin A, including:
1. Cantaloupes
2. Sweet potatoes
3. Carrots
4. Pumpkins
5. Butternut squash
6. Mangoes

What are the Treatment Options for Night Blindness?
The treatment will depend on its causes.
1. Nutrient deficiency (Vitamin A and Zinc) is the easiest to treat. 
2. If the cause is cataract, you can go for cataract surgery to remove the clouded lens and replace it with artificial intraocular lens. Vision is usually dramatically improved after surgery. 
3. For dry eye syndrome, lubricate your eyes with artificial tear drops as they provide instant relief. Just make sure that they are without preservatives. 
4. Diabetic retinopathy can be prevented with tight control over blood sugar, active lifestyle and good dietary habits.
5. As for retinitis pigmentosa, unfortunately there are no treatments available. Thankfully, new research is showing that vitamin A might have a slowing effect on the progression of this eye disease.

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.
