Symptoms You Might Be Suffering From Computer Vision Syndrome

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 an Ophthalmologist.

Eyes need as much regular exercise to keep them healthy as any other organ of the body. Eye exercises are usually designed to provide strength to eye muscles, while improving focus, allowing flexible eye movements and helping stimulate the vision centre of the brain. Eye exercises might not necessarily improve eyesight but they help in preventing eye problems and maintaining the correct eyesight level.

Here are 4 eye exercises that can help strengthen the eye muscles and improve your vision:

1. Blinking - Your eyes get strained due to long hours of sitting at the computer or television and you tend to blink less. Whenever you blink, your eyes stay in darkness for a few microseconds that help to keep the eyes fresh, while reducing eye strain.

2. Palming - This exercise involves three steps:
- Taking a few deep breaths before beginning the exercise
- Make yourself comfortable by resting your elbows on your knees and slowly closing your eyes
- Cover your eyes with the cup of your palm, place your fingers on the forehead and the heel of your hand on your cheekbone

This exercise helps in achieving inner peace and calm and also helps in resting your mind.

3. Figure of eight - This exercise helps in strengthening the eye muscles and provides flexibility. In this exercise, you need to imagine a huge eight in front of your eyes. Slowly turn the 8 on its side. With the help of your eyes slowly trace the figure of 8. Repeat it the other way after a few minutes.

4. Near and far focusing - This exercise helps in strengthening the eye muscles and improves the vision of your eyes. It involves the following steps:
- Either sit or stand in a comfortable position for 2-3 minutes
- Bring your thumb about 10 inches in front of your eyes and try to focus on it
- Now try focusing on an object that is about 10-20 feet in front of your eyes
- Try switching between focusing on the other object and your thumb on each deep breath

Conjunctivitis is the inflammation of the tissue that lies over the white part of the eye and lines the inner side of the eyelid. It is usually the result of a viral infection and can easily spread from one person to another. Conjunctivitis can also be a symptom of STDs like Gonorrhea or Chlamydia. In newborns, conjunctivitis can be vision threatening, while in grownups it is not considered a serious health risk. The symptoms of conjunctivitis differ according to the cause of the infection. 

Some common symptoms of conjunctivitis are:

1. Green or white discharge from the eye
2. Redness of the white part of the eye
3. Inflammation of the eyelid
4. Waking up to crusted yellow discharge
5. Itchiness and burning in the eyes
6. Increased sensitivity to light
7. Blurred vision

An eye examination and testing a sample of the fluid secreted by the eye can be used to diagnose conjunctivitis.  It can easily be treated at home and does not require hospitalization. Antibiotics are often given in the form of eye drops and ointments to treat conjunctivitis. These usually need to be applied 3 to 4 times a day for a period of 5 to 6 days. Wash your eyes before putting the eye drops. Once applied, close your eyes and roll the eyeball around to distribute the medicine and keep it from overflowing out of the eye. Wash your hands immediately after applying the eye drops.

Viral conjunctivitis is highly contagious. If you are suffering from it, you should take a few days off work and restrict your social interactions. Wash your hands frequently as you may unconsciously rub your eyes. This is especially important with regards to meals and finger foods. Also, avoid sharing towels, pillowcases, etc. to minimize the transmission of the disease from one person to another.  

Avoid using makeup while being treated for conjunctivitis. With conjunctivitis, the eye is more sensitive to irritants and thus, a speck of makeup can worsen the situation. Also avoid contacts. If you wear contacts regularly, dispose the current set and start using a fresh set after your doctor gives you a clean chit. 

Artificial tears or non prescription eye drops can also be used to relieve the itchiness and burning in the infected eye. If only one eye had been affected by conjunctivitis, do not use the same eye drop bottle for both eyes.

Conjunctivitis is often caused by bacterial, chlamydia infections and allergic reactions, hence wear sunglasses for better comfort outdoors, and avoid rubbing your eyes Consult eye specialist if condition worsens, or if you experience blurred vision.
