I am suffering from strain in my eyes and also pain head and lower neck back due to hard working mobile repair.
Due to continuous work of what you described, your eyes get strained and you suffer from headache. Due to bending you r getting neck pain and it also causes headache. So if you can't change your work try to handle it well. First get eye sight check up as this also causes same problems of eyes strain. To prevent over bending use a high table or lower chair to sit so that your working should be as high as possible to prevent strain on your neck. Take breaks in between. Do eye exercises and neck strengthening exercises. Do meditation.

Types and Treatment for Astigmatism

MBBS, MS - Ophthalmology, Diploma in Ophthalmology , Fellowship in Cornea and Anterior Segment
Ophthalmologist, Ahmedabad
Types and Treatment for Astigmatism

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:

  1. Corneal astigmatism: It happens when your cornea itself is distorted.
  2. 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:

  1. A family history of astigmatism or other eye issues like dislocation of the cornea.
  2. Scarring or diminishing of your cornea
  3. Excessive partial blindness, which makes foggy vision at a separation
  4. Excessive farsightedness, which makes hazy close-up vision
  5. A past of eye surgeries, for example, cataract surgery (surgical expulsion of a blurred focal point)

Symptoms: The side effects of astigmatism include:

  1. Hazy, Bended, Or Fluffy Vision At All Separations (Close-Up And Far Away)
  2. Trouble seeing during evening
  3. Lazy eye
  4. Squinting
  5. Irritation in the eye
  6. Cerebral Pains

Diagnosis:

  • 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.

Treatment:

  • 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:

  1. Laser in situ keratomileusis (LASIK)
  2. Photorefractive keratectomy (PRK)
  3. 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.

Ophthalmologist Verses Optometrist (Spectacle Dispenser).

MBBS, DOMS, MS - Ophthalmology, , Fellowship in phacoemusification
Ophthalmologist, Patna
Ophthalmologist Verses Optometrist (Spectacle Dispenser).

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.

 

Regards

Dr Arjun Kumar Singh

Medicines do provide relief but whats more important is lifestyle modification for long term relief. No permanent cure but permanant life style changes will help, follow these instructions: take frequent breaks while you are working every 20-25 mins take break to look away from screen blink more frequently' level of screen should be below the level of eyes ac should not blow directly on your face.

This condition is called Eye strain, or asthenopia, in which the eyes get tired from excessive or intense use. It can be annoying, but it tends to disappear with rest. Although it’s not often a serious condition, eye strain could be a symptom of an underlying problem. Eye strain is known to cause fatigue, difficulty concentrating, and headaches Eye strain may lead to other problems, such as: •Headaches •Difficulty Concentrating •Irritability •Burning Sensation •Watery Eyes •Dry Eyes •Photophobia •Eye Pain. While watching TV/Mobile and studying make sure that the lightening in room is proper and you are at least at a distance of 10 Feet from TV to reduce and negate the effects. You can also reduce the intensity of the TV/Mobile screen by attaching a filter or by getting an eye-friendly screen. Above all, one must try to reduce the amount of TV/Mobile usage or take frequent breaks. You can also use zero number prescription glasses to reduce straining your eyes----- Homoeopathic medicine CINELUBE EYE DROPS (HAPDCO) Pour 2 drops 3 times daily.

Hello lybrate-user. You could consider the option of refractive surgery (lasik. Operations done to remove the refractive error (power) of the eyes are known as refractive surgery (lasik). There are certain basic criteria that most patients need to fulfill before they can safely undergo refractive surgery. To enumerate, they are: (1) stability of refraction: the power of the eyes should have become stable for a period of 1.5 years minimum without any change. (2) curvature of the cornea should be tested by a technique which is known as topography. (3) thickness of the cornea should be measured by a test known as pachymetry. The minimum thickness required is 550 microns. (4) dilated retina evaluation: this is one of the most important tests that should be performed by a trained retina specialist. This test helps in detection of any offensive lesion on the central or peripheral retina. In case of any retinal abnormality, these should be treated before undergoing the surgery for number reduction. (5) there should be no pre-existent corneal abnormality. (example: corneal scar, opacity, defect, etc.) another important suggestion is that whenever you go for the assessment (the above mentioned tests), you should discontinue the use of contact lenses at least 4 weeks prior to the assessment. The reason for this being that use of contact lens temporarily alters the contour of the cornea. It takes around 3-4 weeks for the restoration of the original corneal contour after removal of the contact lens. Another important point is that you, as a patient, should be compliant to put post operative medication in your eyes for at least 2 months. There is bound to be some discomfort, watering, foreign body sensation, pain after the surgery in most cases-you should be ready to tolerate that. A leave from work for 7-10 days after the surgery should be generally sufficient. Last but not the least, you should set realistic expectations from this surgery. Though extremely rare, there is a remote possibility that the surgery may need to be repeated. Also, the need for subsequent treatment for the eye may be required. Thus, you should be compliant enough to trust and follow your eye specialist. In case you have any other queries, feel free to contact me. Hope my suggestions help you, take care, regards.

At the age of 24 years being hypertensive is unusual ,so first try to take help of yoga & natural diet to CURE hypertension, you should get yourself checked up whether you are having really Squint or just exophoria, so consult in higher institution whether you really need surgery or just exercise. Cost of squint surgery is around 30 thousands depending on hospital, with regards.
