Astigmatism is an eye condition where there is an imperfection in the curvature of the cornea. The cornea and lens are smooth and equally curved in all directions, which helps to focus the light rays to the retina. But if there is an imperfection in the curvature, then you will suffer from a refractive error. Astigmatism is not an eye disease. It is simply a condition where the eye is not able to focus the light.
Irregular shape of the cornea is the main cause for astigmatism. It might also be caused because of the imperfect shape of the lens. Suffering from astigmatism is very common. You are either born with the condition or you might have developed it after an eye surgery. It is an incorrect concept that watching too much of television or reading without enough light causes astigmatism.
There are three different types of astigmatism:
- Myopic astigmatism: When the principal meridians of the cornea are nearsighted.
- Hyperopic astigmatism: When the principal meridians of the cornea are farsighted.
- Mixed astigmatism: When one of the principal meridians is nearsighted and the other is farsighted.
It can also be classified in two other types:
- Regular astigmatism: When the principal meridians are perpendicular to each other.
- Irregular astigmatism: When the principal meridians are not perpendicular to each other.
Blurry or distorted vision, strain in the eye, eye discomfort, squinting and headaches are a few symptoms of astigmatism
If you notice the symptoms stated above, make sure you pay a visit to your ophthalmologist. If you are suffering from astigmatism, your doctor will do an eye test to check how much your eye is able to focus on light. After conducting his tests, he will determine how much power you have and you will have to wear glasses of that power. Apart from the option of wearing glasses or artificial lenses, you can also go for a surgery to correct the condition. LASIK is an option among the many other options of surgeries available.
Eat foods rich in sulphur. Foods like fish, green vegetables, pineapple, garlic, onion, olive oil, etc are rich in sulphur. Hence, eating these will help you battle astigmatism.

Respected sir, I am Adnan my eyes is very red before three day. What I m do, and also very pain in my eyes, water running is also in my eyes.
Whenever I read for like 4 hour my head start heating. Headache too. Tried medicine like metacin. But it gives just temporary relief. Tried hoga but not daily. I have numbers in eye. Can it be reason?
In past 2 days I hav severe eye pain and I wear spec instead of that I can not tolerate my pain what should I do?
I am getting my eye sight down day by day even after using glasses. Is there any natural way to fix or recover it. please suggest.
Considering lasik lasers (for eye glass removal) for their eye glass removal. One must read this as it has some serious implications/complications if done in haste.
There are lot of benefits by being myopic (eye power less than -3 d) and disadvantages in going for lasik laser in young age with low eye power.
You may never need glasses after 40 years (presbyopia) of age for reading if you use glasses or contact lens now instead of getting your glasses removed by lasik lasers (for powers less than - 3d and around -3d) but after lasers you may need the same so going for laser may keep you free from glass for roughly 15 to 20 years only. The myopia can come back even after lasik surgery.
There are variety of complications with lasik lasers like glare, halo and problem in colour contrast, dry eyes, problem in night vision, serious complications like corneal ectasia (may need corneal transplant) although advancement in lasers has minimized these issues still one should refrain from it since the percentage of side effects are highly underplayed
The disadvantages according to my experience outweighs the benefits in young age for those with low myopia (-3d) and considering the risks involved and amount of side effects associated with it which are highly under reported by the doctor.
Lasik operated emmetropic (having normal eye power) are not allowed in airforce, railways and army.
If you are young and advised for lasik in haste without giving due consideration about thickness of cornea, it may result in complications after 5 years and can affect rest of your life.
If you are having high eye power (more than -3d) then there are various issue which should be taken in consideration.
First and foremost, the corneal (outer membrane for eye) thickness must be measured by pachymetry. Indians have a thinner cornea around 400 to 450 micron as compared to western population (around 600 micron).
The critical thickness of cornea must be above 300 micron even after lasik lasers to avoid/minimize future complications.
Since laser burns the cornea, for removing every 1d of eye power, there is a reduction in 35 micron thickness in cornea.
Indians with average thickness of 400 to 450 micron thickness can only go upto 35*5= 175 micron reduction to ensure that their corneal thickness remains above crucial thickness of 300 micron.
So patients are advised to take a independent opinion from a experienced ophthalmologist preferably before going for lasik laser since procedure done on wrongly selected patient can lead to life long complication for the patient.
One can use contact lenses which have become quite advanced with time, if one does not want glasses. All that glitters is not gold and not every side effect can be predicted.

A fundamental aspect of eye care and the long-term prevention of vision loss for patients with diabetes mellitus involves the identification of specific retinal pathologies and the subsequent determination of the severity of diabetic retinopathy. Traditionally, this has been accomplished through individualized assessments by experienced eye care professionals, preferably following pupillary dilation. However, given that it is estimated that there will be more than half a billion persons with diabetes by 2030, necessitating nearly 2000 eye examinations per minute just to evaluate those in need once every year, this approach to retinal evaluation is unlikely to be sustainable by health care systems globally. Furthermore, despite multiple national and international initiatives to increase access and promote awareness regarding the need for eye examinations for all persons with diabetes, only approximately 18% to 60% of persons undergo examinations that attain the recommended ocular examination guidelines.
