Computer Eye Problem :-

Computer Vision Syndrome

Computer vision syndrome (CVS) is a temporary eye vision problem resulting from focusing the eyes on a computer display for prolonged, uninterrupted periods of time.

Different problems encountered after prolonged use of computers. You can have some of these problem

  • Headaches
  • Eyestrain
  • Neck ache and backache
  • Blurred vision
  • Dry & Irritated eyes
  • Sensitivity to light
  • Double Vision
  • Red eyes
  • Contact lens discomfort
  • Glare sensitivity
  • Slowness in changing the focus of your eyes
  • Excessive tearin
  • Changes in color perception
  • Excessive tearing

Reasons for CVS

When using the computer your blink rate decreases by a drastic 70 percent. Generally speaking it means that instead of blinking an average of 14 times per minute, you are now blinking 7 times per minute.

  • If your eyes are dry or irritated, use eye drops to moisturize and lubricate
  • Place reference to typing materials close to the computer screens.
  • Blink frequently
  • Visual breaks: A good rule of thumb is 20/20, 20 minutes, look 20 feet away for 20seconds.
  • Avoid shifting at a location with direct blower or an A.C or for a long period in a room with low humidity
  • Install a glare guard, an optically coated glass anti-glare filter.
  • Use a non-reflective paint or coverings on the walls.
  • Make sure there is sufficient light to read hard copy without straining.
  • Use a stand for hard copy so that source documents and the computer screen are at roughly equal distance from the eyes.
  • Adjust the height of your desk or chair so the middle of the computer screen is about 20 degrees below eye level. The screen itself should be 16- 30 inches from your eyes.
  • Choose screens that can tilt and rotate. A keyboard that you can adjust is also helpful.
  • Electrostatic charge on the computer which attracts & accumulates dust particles which can cause skin rash or irritation in sensitive individuals, clean computer screen regularly.
  • Adjustable chair.

Diabetic Eye Problem :-

Preventing diabetes related eye problems

You can do a lot to prevent diabetes eye problems.

  • Keep your blood glucose and blood pressure as close to normal as you can.
  • Have an eye care professional examine your eyes once a year. Get this examination even if your vision is OK. The eye care professional will use drops to make the black part of your eyes-pupils-bigger. This process is called dilating your pupil, which allows the eye care professional to see the back of your eye. Finding eye problems early and getting treatment right away will help prevent more serious problems later on.
  • Ask your eye care professional to check for signs of cataract & glaucoma. See if you are planning to get pregnant soon, ask your doctor if you should have an eye exam.
  • If you are pregnant and have diabetes, see an eye care professional during your first 3 months of pregnancy.
  • Don't smoke.

Diabetes problems

Too much glucose in the blood for a long time can cause diabetes problems. This high blood glucose, also called blood sugar, can damage many parts of the body, such as the heart, blood vessels, eyes, and kidneys. Heart and blood vessel disease can lead to heart attacks and strokes. You can do a lot to prevent or slow down diabetes problems.

Staying healthy with diabetes

  • Healthy food.
  • 30 minutes exercise
  • Regular medicines
  • Regular blood glucose checking
  • Check your feet everyday for cuts, bruises
  • Daily brush & floss teeth
  • Blood pressure control
  • Don't smoke

Diabetes can cause problems in your eyes

High blood glucose and high blood pressure from diabetes can hurt four parts of your eye:

  • Retina. The retina is the lining at the back of the eye. The retina’s job is to sense light coming into the eye
  • Vitreous. The vitreous is a jelly-like fluid that fills the back of the eyes exercise
  • Lens. The lens is at the front of the eye. The lens focuses light on the retina
  • Optic nerve. The optic nerve is the eye’s main nerve to the brain.

Retina problems because of diabetes

Retina damage happens slowly. Your retina have tiny blood vessels that are easy to damage. Having high blood glucose and high blood pressure for a long time can damage these tiny blood vessels.

First, these tiny blood vessels swell and weaken. Some blood vessels then become clogged and do not let enough blood through. At first, you might not have any loss of sight from these changes. Have a dilated eye exam once a year even if your sight seems fine.

One of your eyes may be damaged more than the other. Or both eyes may have the same amount of damage.

Diabetic retinopathy is the most common diabetes eye problem.


  • New blood vessels grow.
  • New blood vessels are weakand leak blood into the vitreous of your eye.
  • The leaking blood keeps light from reaching the retina.
  • You may see floating spots or almost total darkness. Sometimes the blood will clear out by itself. But you might need surgery to remove it.
  • Over the years, the swollen and weak blood vessels can form scar tissue and pull the retina away from the back of the eye. If the retina becomes detached, you may see floating spots or flashing lights.

Different efforts which can reduce the chances of retinal problems

Keep your blood glucose and blood pressure as close to normal as you can.

Your eye care professional may suggest laser treatment, which is when a light beam is aimed into the retina of the damaged eye. The beam closes off leaking blood vessels. It may stop blood and fluid from leaking into the vitreous. Laser treatment may slow the loss of sight.

If a lot of blood has leaked into your vitreous and your sight is poor, your eye care professional might suggest you have surgery called a Vitrectomy.

vitrectomy removes blood and fluid from the vitreous of your eye. Then clean fluid is put back into the eye. The surgery can make your eyesight better.

Symptoms of diabetes caused retinal problems

You may not have any signs of diabetes retina damage, or you may have one or more signs:

  • Blurry or Double vision
  • Rings, Flashing Lights, or Blank Spots
  • Dark or Floating Spots
  • Pain or Pressure in one or Both of your eyes
  • Trouble seeing things out of the corners of your eyes
  • If you have retina damage from diabetes, you may have blurry or double vision.

Other eye problems related with diabetes

You can get two other eye problems-cataracts and glaucoma. People without diabetes can get these eye problems, too. But people with diabetes get these problems more often and at a younger age

  • A cataract is a cloud over the lens of your eye, which is usually clear. The lens focuses light onto the retina. A cataract makes everything you look at seem cloudy. You need surgery to remove the cataract. During surgery your lens is taken out and a plastic lens, like a contact lens, is put in. The plastic lens stays in your eye all the time. Cataract surgery helps you see clearly again.
  • Glaucoma starts from pressure building up in the eye. Over time, this pressure damages your eye’s main nerve-the optic nerve. The damage first causes you to lose sight from the sides of your eyes. Treating glaucoma is usually simple. Your eye care professional will give you special drops to use every day to lower the pressure in your eyes. Or your eye care professional may want you to have laser surgery.


Children Eye Problem :-

First Eye Examination of Child

Infants must have an eye examination during their first 12 months of life. Choose a time when he or she is usually alert and happy.

Eye Examination of Child

It is advisable to demonstrate & explain to the child what will happen during a vision checkup. This will help to reduce any anxiety your small child might be experiencing. It also helps to learn about your child's specific fears and concerns so that you can take corrective measures ahead of time.

  • Act out some of the procedure to guess the worries that your child might not be able to articulate.
  • Reassure your child that you will be there with him or her during the entire procedure.
  • Make your child realize that the check-up is not a punishment but rather a way to guarantee the healthiest vision possible.
  • Respect the wishes of an older child who might not want you to be present during the procedure. Privacy is important to adolescents and should be protected.
  • Inform your eye doctor if you have a family history of eye problems requiring vision c orrection, such as nearsightedness or farsightedness (refractive errors), lazy eye (squint/weak eye), or eye diseases.

Psychological Problems with Undiagnosed Vision Problems

Children who have undiagnosed vision problems can suffer from low self-esteem. They can become frustrated more easily, have trouble concentrating on reading, feel stupid, experience frequent headaches, or rub their eyes.

Once their vision is corrected, children with eyeglasses hold their heads high and exude confidence---if their parents are positive and supportive.

Making Child comfortable with Spectacles

  • The child needs to have a nice feeling after wearing specs. Thin, lightweight plastic and photochromic lenses, and so many neat frames, can make your child feel enthusiastic about wearing glasses to emulate older kids or express an individual sense of style.
  • Photochromic lenses, which change from light to dark when ultraviolet light is present, provide 100% protection from harmful UV rays and glare. This makes child enthusiastic to wear glasses. Children like to wear glasses that darken in the sun.
  • Make certain that your child feels a part of the frame selection process. Nothing is more important in terms of getting children to wear their glasses and take better care of them as well.

Common Eye Problems in Children

Eye tests and general examinations often are conducted to detect the possible presence of these types of eye problems commonly found in young children:

Decreased vision your Childs’s eye may have some vision problem. The child should be examined to provide the best possible vision with glasses.

Lazy eye (amblyopia)

Your child's eyes should be examined for early detection of vision problems such as lazy eye or amblyopia, in which one eye is weaker than the other. With amblyopia, eye patching often is used to help strengthen the weaker eye.

Unfortunately, amblyopia is not always correctable with eyeglasses or contact lenses and may require eye patching to strengthen the weaker eye

Misalignment of eyes (strabismus) - Crossed or misaligned eyes can have different causes:

  • Problems with muscle control in the affected eye or eyes. If strabismus persists in young children, a condition known as lazy eye or amblyopiacan develop along with related vision problems.
  • Inability to maintain alignment of both eyes for correct focus as distant objects move nearer (convergence insufficiency)
