I am suffering from strain in my eyes and also pain head and lower neck back due to hard working mobile repair.
Astigmatism is a typical vision problem that occurs when the shape of the cornea is distorted due to injuries or other causes. With astigmatism, the lenses of the eye or the cornea curves. This irregular curve can change the way light refracts or passes through your retina. This causes hazy, fluffy, or twisted vision. Farsightedness and partial blindness are two different sorts of issues with the way light goes to your retina. Farsightedness is called hyperopia. Partial blindness is called astigmatism.
Types: There are two types of Astigmatisms. These are:
- Corneal astigmatism: It happens when your cornea itself is distorted.
- Lenticular astigmatism: Lenticular astigmatism happens when your lens is distorted.
Risks: Astigmatism can happen in youngsters and grown-ups. Your danger of creating astigmatism might be higher if you have any of the following:
- A family history of astigmatism or other eye issues like dislocation of the cornea.
- Scarring or diminishing of your cornea
- Excessive partial blindness, which makes foggy vision at a separation
- Excessive farsightedness, which makes hazy close-up vision
- A past of eye surgeries, for example, cataract surgery (surgical expulsion of a blurred focal point)
Symptoms: The side effects of astigmatism include:
- Hazy, Bended, Or Fluffy Vision At All Separations (Close-Up And Far Away)
- Trouble seeing during evening
- Lazy eye
- Irritation in the eye
- Cerebral Pains
- Visual Acuity Assessment Test: Patients are required to read letters from a graph at a particular distance to decide how well they can see the letters.
- Refraction Test: A refraction test uses a machine called an optical refractor. The machine has various remedial glass lenses that are used to read an outline while looking through lenses on the optical refractor.
- Keratometry: Keratometry is a route for your specialist to measure the bend of your cornea. They will do this by taking a look at your eye through a keratometer.
- Corrective Lenses: Remedial eyeglasses and contact lenses prescribed by a specialist are the most well-known and least obtrusive solution for astigmatism.
- Orthokeratology: Orthokeratology is a treatment that uses contact lenses to correct the deformation and flow of your cornea. You will wear inflexible contact lenses for certain time-periods. It is easier to wear them while you are sleeping and remove them during the day.
Surgery: Your specialist may suggest refractive surgery if your case is a serious one. This kind of surgery includes use of lasers or little blades to reshape your cornea. This will correct astigmatism permanently. The three basic surgeries for astigmatism are:
- Laser in situ keratomileusis (LASIK)
- Photorefractive keratectomy (PRK)
- Spiral keratotomy (RK).
All these surgeries might carry some risks depending upon the symptoms of your problem. As innovation advances, it is very important for the patient to explore more options before choosing which refractive surgery is a good fit for him or her. If you wish to discuss about any specific problem, you can consult a ophthalmologist.
Do you think the corporate spectacle sellers (including online) with a chain of shops the optician at the corner of your road can diagnose and treat you for your eye vision problem completely accurately (even a simple case like myopia)?
Think again. Once the damage is done, it is mostly irreversible.
Signs of near sightedness (myopia)- include blurring of vision, genetic predisposition if mothers and fathers are myopic, squinting (bhengapan), eye strain headache, feeling fatigued when driving or playing sports, malignant myopia where the vision loss can be rapid due to elongation of eyeball and is irreversible. Similarly there are various reasons for presbyopia, astigmatism.
The people with high myopia may suffer from retinal detachment (laser is required for its correction).
An optometrist is incompetent/not trained to look behind your lens. If he misses the retinal detachment and does not refer you to the eye surgeon, you will have to face the consequence.
In case of compound power, it is purely the competence of optometrist which will help in determining the power of lens. Many cases are coming up with wrong power calculation. It is advisable to consult an eye surgeon before going to a spectacle shop. Once the eye power has increased, it cannot be lowered without surgical intervention.
It's for the patient to decide whether he considers optometrist (guys with degree in power calculation sitting in corporate and local eye shops, authorized to calculate eye power, competent enough to diagnose even these condition completely and afford to miss the retinal detachment and silent diseases like glaucoma or other associated eye pathology if they are present in eyes.
The patient's power will increase through incorrect or incomplete diagnosis and harm his eyes. It's your eyes, always consult an experienced eye surgeon before you go to any spectacle shop to buy your spectacles?
There are silent and irreversible disease in family like glaucoma/kala motia which have a family history, it is the duty of the doctor to ask history of such disease.
Can you expect your local optician to ask such history? if he misses your glaucoma by not checking your eye pressure, you vision loss is irreversible.
The guy sitting in spectacle shop may sell you a branded eyeglasses, give a very good deal and pamper you with snacks but what purpose it serves if the some part of your diagnosis is missed and causes irreversible loss of vision.
The optometrist is trained just in power calculation and dispensing of contact lenses. He is not trained to diagnose and treat any eye disease, look behind the lens through indirect opthalmoscope, use instruments like slit lamp.
He is incompetent to treat any eye disease like amblyopia/lazy eye.
If he is giving medicine/drugs along with dispensing of spectacles, he is most probably committing a crime.
If you are going to optometrist first, it purely depends on his training and expertise whether he is able to suspect any associated pathology or not and refers you the eye surgeon and if he misses it or makes a wrong diagnosis, the loss is yours and only yours. Lastly the optometrist will be never held responsible for wrong diagnosis.
The doctor's prescription caries a legal value and he will always advice in patient's best interest.
