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.

There are several traditional methods used to correct vision, including wearing corrective lenses, or having eye surgery. However, with a few natural home remedies, eye exercises and general lifestyle changes you can improve your eyesight naturally.
The following eye exercises work to strengthen the eye muscles and maintain the flexibility of your eye lens in order to improve your vision. Some of the most popular exercises include:
Breathing Yoga Exercises:
This will encourage conscious breathing. The point of this is to relax your body and close your eyes. This allows the muscles to relax. Breathe in through the nose and out through the mouth for two minutes. When you finally open your eyes after two minutes, do not focus on anything. Repeat the exercise three times.
Each time you blink you are soothing and moisturizing your eyes. This can be done anywhere if your eyes are feeling weary or tired. Blink consistently for 4 to 5 seconds at a time for a period of two minutes.
These exercises were specifically designed to stimulate the various acupuncture points around your eyes. This aid in relaxing the muscles in and around your eye and helping to calm the mind. To execute this exercise you should place your elbows on a flat surface in front of you with your left palm covering your left eye. Your fingers should be resting on your forehead. Do the same with your right eye and right palm. The palms should cup the eyes, but not put any pressure on them. You should do this exercise for a period of three minutes.
It is important to eat the proper diet to promote eye health. This includes the addition of certain vision-enhancing foods if you currently do not consume them:
Bilberries: Fruit that is rich and full of antioxidants. These will aid in protecting the eyes from free radicals. They will also aid in better blood circulation in your eyes.

Other Eyesight Enhancing Tips
The fact is that it is much smarter to prevent eye problems, rather than treat them after the problem is present. While eye exercises and a healthy diet are important to your overall eye health, there are other tips you can use that will help to naturally improve your eyesight.
Minimize the extended period of time that you spend in front of the computer screen. Be sure to use our 10-10-10 rule while on the computer.
After every half-hour of television watching take a 10 minute break. This will provide a break for your eyes.
Try to look at objects far away when you take a break from in front of the TV or computer screen.
When your eyes feel tired or worn out, try washing them with cold water.
When they feel extremely tired, close them for a while to allow them to rest. The old saying is “take 5 to stay alive”.
When it comes to eye health, you must treat them as any other system in your body. This means providing exercise, and the proper nutrients. However, these are not the only elements that aid proper eye health.
In addition to the tips listed here, you also need to ensure that you receive plenty of sleep each day. You need to try to achieve six to eight hours each night to allow your eyes to fully rest and rejuvenate. If you do not get enough sleep, you may find that you have an abnormal amount of eye health issues.
Another important factor is to drink plenty of water. The body is composed of mainly water, meaning that you must replenish it regularly. This will help provide moisture to cleanse dust and debris from your eyes throughout the day. Water is essential for all of the body’s functions, including proper and healthy eyesight. In most cases drinking eight, eight-ounce glasses of water a day will provide enough moisture and water for your body.
However, if you live in a dry area, more is necessary to provide optimum eye health.
Taking care of your eyes is a life-long process. This includes preventing eye health issues, as well as the need to wear corrective lenses. There are thousands of success cases and studies that tell the benefits of proper eye health and preventative measures that you can take at home. The home remedies and lifestyle changes here will make a huge difference in the overall eye health that you have.
