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. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.

I am affected by eye infection it happens many times in a month and once it happens then it take 2-3 day to normal and it is very painful for me.
Myth: Staring at a computer screen all day is bad for the eyes.
Fact: Using a computer does not damage your eyes. However, staring at a computer screen all day can contribute to eyestrain or tired eyes. People who stare at a computer screen for long periods tend not to blink as often as usual, which can cause the eyes to feel dry and uncomfortable. To help prevent eyestrain, adjust the lighting so it doesn't create a glare or harsh reflection on the screen, rest your eyes briefly every 20 minutes, and make a conscious effort to blink regularly so that your eyes stay well lubricated.

Eyelid surgery or Blepharoplasty is a cosmetic surgery, which is used to correct droopy eyelids. It reduces the saggy quality of lower eyelids which you get with age and also rids of the excess skin from the upper lids. Apart from making your eyes look younger, Blepharoplasty also enhances your peripheral vision which can get affected due to sagging skin. An eyelid surgery does not help you get rid of dark circles or crow's feet which you get on the outer corner of your eyes.
Reasons to Consider Eyelid Surgery
Eyelid surgery is a good option if you want to get rid of the sagging skin from your lower eyelids or the excess skin on your upper eyelids. Sometimes with age your lower eyelids may appear puffy, making you look old and exhausted all the time. An eyelid surgery can make your eyes look younger and livelier and also do away with the grooves and lines formed under your eyes.
Precautions to take after the Surgery
You need to stay indoors after the surgery for more than a week for your eyelids to heal. You may suffer from dry eyes; so always keep ice packs handy. Your doctor may prescribe eye drops or artificial tears, according to your needs. Make sure you always use clean towels and consume painkillers only if your doctor recommends.
It is of primary importance to follow up the surgery with postoperative care. Your doctor will give you detailed information about dressing, a dosage of antibiotics, activity level allowed and also the complications which can arise. Make sure you follow all the instructions and are prepared for the symptoms associated with it.
Risks associated with Eyelid Surgery
Fortunately, major complications associated with Blepharoplasty are rare; yet there could be some side effects of this surgery. Sometimes, there might be cases of infection and bleeding or a bad reaction to anesthesia. Hematoma or accumulation of blood under the skin is also one of the side effects of eyelid surgery.
