With technology at your fingertips, it is hard to think of times when the existence of laptops and television sets was unimaginable. Technology is common enough to be taken for granted in present times. TV and laptops are especially in widespread use. The primary reason could be entertainment, an urge to connect to the larger world, or the need to kill time. Such dependability leads to severe health hazards. Read on to find out more:

Effects of TV and laptops on your health:

    Sleep deprivation: Long hours of exposure to artificial light can lead to sleep deprivation.
    It can also lead to serious vision problems: Watching TV or using laptops for long hours can make your eyes vulnerable to constant glare. You fail to realize, but changing lights of a computer screen or of a television set in a dark room can be extremely strenuous for your eyes to adjust. Constantly changing lights can lead to glaucoma. However, dry and itchy eyes, headaches and poor vision are the commonly noticed effects.
    It causes obesity in children and adults: Since all your work can be done on the internet, you tend to become lethargic. You are too lazy to go to the market or to the bank. Even if you are not watching you use the television for background music. Adults therefore do not make qualitative use of their free time. Children are addicted to playing games and browsing sites on the laptop. They hardly indulge in outdoor games. This leads to obesity in adults and children all the same.
    Propels your desire to eat fast food or packaged food: Binge eating is a very common practice while watching TV or using laptops. Chips, pizzas, burgers, ice- creams, cold drinks and absolutely anything junk devoid of nutritional value are more liked by us. Junk food not only leads to weight gain but is also detrimental to our digestive system.
    Can increase the risk of infertility in men: Laptops heat up when used for a long span of time. This heat can increase scrotum temperature which results in reduced sperm production, leading to infertility.   

As is said, nothing in excess is good for your health. It is therefore, best to make controlled use of TV and laptops to avoid its harmful effects.

Watching TV and Using Laptop: How it Affects Your Health?

Glaucoma is a group of diseases that causes damage to your eye's optic nerve and gets worse over time. The optic nerve is a bundle of millions of nerve fibres which carry visual impulse from the retina at the back of eye to the brain. The increased Eye pressure, called intraocular pressure, can damage the optic nerve and fasten the natural nerve fibre loss. Since nerve cells can't regenerate this damage is permanent and irreversible.

Without treatment, glaucoma can cause total permanent blindness within a few years. Because most people with glaucoma have no early symptoms or pain from this increased pressure, it is important to see your eye doctor regularly so that glaucoma can be diagnosed early and treated before significant functional visual loss occurs.

If you are over age 40 and have a family history of glaucoma, you should have a complete eye exam with an eye doctor every one to two years. If you have any risk factors, you may need to visit your eye doctor more frequently.

What Are the Symptoms of Glaucoma?

For most people, there are usually few or no symptoms of glaucoma. The first sign of glaucoma is often the loss of peripheral or side vision, which can go unnoticed until late in the disease. This is why glaucoma is often called the "Sneak Thief of Vision" or "Silent Thief of Eye Sight".

If you have any of the following symptoms, seek immediate medical care:

Seeing halos around lights
Vision loss
Redness in the eye
Eye that looks hazy (particularly in infants)
Nausea or vomiting
Pain in the eye
Narrowing of vision (tunnel vision)
Risk Factors

There are several risk factors, which may lead to glaucoma, such as

Age of the individual
Ethnicity- African, Caribbean, Hispanics and Asians are at higher risk
Increased eye pressure or IOP History of glaucoma in family or relatives
Presence of Myopia or Hyperopia
Previous eye injuries
Use of steroids- as injections, tablets, eye or ear drops or ointments or protein supplements for muscle building in gyms or inhalers
Previous history of anemia
Individuals conditions affecting blood flow like hypertension, diabetes or high blood sugar, migraine etc are also at risk.
Treatment-

The treatment for glaucoma relies on the nature and seriousness of every case. Generally, glaucoma cannot be totally cured, but it can be controlled. Eye drops, pills, laser strategies, and means of surgery are utilized to maintain and prevent further harm from happening. Talk to your eye doctor to find out if you are at risk of developing glaucoma.

Glaucoma - 7 Signs You Are Suffering From It!

A common headache can have a number of reasons behind it, such as defective vision, hetrophoria or convergence deficiency, etc. Now, the question arises as to how they can cause headache. Read on to know more...

Q. Why should defective vision cause headache?

To attain a perfect vision, eyes with defective vision have to make sustained extra efforts, which results in headache. Even if the refractive error is very small, it can be the cause of headache. More prolonged the working and smaller the print, higher the incidence of headache.

Q. Can this occur at all ages?

Yes, it can occur at all ages. However, with age, the resistance decreases and hence elderly people are more prone to get headache. More the use of computer, mobiles, TV or prolonged studies precipitates headache

Q What is Hetrophoria?

Normally, both eyes always remain parallel, but in some cases, eyes have slight tendency to develop minor squint, may be convergent or divergent. This is called Hetrophoria or Latent squint. Such patients have to take extra strain to keep the eyes straight

Q. What is convergence deficiency?

For reading, both eyes have to converge and if there is weakness of convergence, extra strain has to be put on the eyes, which cause headache.

Q. What is the ideal method of refraction in young patients, I,e below 40 years?

Ideal method is to dilate the pupil with Tropicasyl plus drops. This has the advantage that the doctor can see the retina and Optic Disc. This is important to exclude any involvement of brain as the cause of headache. It also relaxes accommodation and hence provides correct refraction. In cases of Hypermetropia, it is extremely essential to dilate the pupil.

Q. What is the role of Autorefractmeter (a computer) in refraction?

It is a very important instrument to provide correct refraction, but it cannot be totally relied upon. Some opticians rely on it and give wrong numbers.

Q. What is acceptance Test?

You have refracted the eyes with Autorefractmeter or Streak Retinoscope but exact power is what a patient accepts. This is very important.

Q. What is astigmatism?

There is a difference in refraction in different meridians and it is important that a cylinder number is prescribed in correct axis. This is a difficult task and needs lot of experience.

Q. Is it important to correct astigmatism?

To relieve headache and strain on the eyes, it is very important that exact cylinder is prescribed.

Q. What is the role of exact centring of Optical Lenses?

You may give correct number, but if the centre of the Optical lenses and cornea do not coincide, satisfactory results are not obtained. To dispense correct lenses is a big art and the Optician must be qualified and well experienced.

Q. Does the quality of lens affect the visual comfort?

Yes, it is important that quality of lenses should be good, preferable fibre lenses which are Ant reflect coated. Crizal coating with capability to block the UV rays are very popular.

Conclusion: Refractive errors are important cause of headache and needs proper examination of the eyes, preferably after dilating the pupil. Astigmatic error even if too small may be the cause of headache. Spectacle dispensing is an art and a patient must select proper optician. Spectacles if advised for constant use must be used constantly to get full relief.

Defective Vision - Can it be a Cause of Your Headache?

Glaucoma is a type of eye disease in which the optic nerve of the eyes get damage. The problem gets worse over time and leads to a condition where a person is not able to see, thus blindness.

Glaucoma can also cause due to the pressure buildup inside the eyes. This buildup of pressure is known as intraocular pressure which leads to damage the optic nerve. The optic nerve of the eyes is responsible for transmitting images formed on the retina to the brain. Due to the damage of this optic nerve, people suffering from Glaucoma may lose their vision completely and permanently.

Glaucoma is one main leading cause of blindness all over the world. For treating Glaucoma, there are many options and surgical methods are available. However, Ayurveda is one of the most effective methods to cure this problem naturally and completely.

Symptoms

The problem usually does not show any early symptoms. However, some of the common symptoms that may occur due to Glaucoma are:

Seeing halos around lights

Red eyes

Vision loss

Lazy eyes

Nausea

Vomiting

Eye pain

Narrowed vision

Ayurvedic Treatment of Glaucoma

Ayurveda is known for its wisdom in treating body ailments in the most natural and effective way. Ayurveda seems to have a cure for every ailment and this is true for Glaucoma. There are many herbs and therapies available which help in relaxing the pain, reduce the redness, drain the deposited fluid, improves vision, etc.

According to Ayurveda, any problem is caused due to the disturbance of balance in the doshas. It says that the disturbance of Kapha dosha may lead to Glaucoma.

Among various herbs used in Ayurvedic treatment, some of the herbs used in Ayurveda to treat Glaucoma are:

Punarnava (Boerhavia diffusa): It is one of the leading herbs used to cure the Glaucoma. It has the diuretic properties which help in controlling the disease by draining the excess fluid from the eyes. It also prevents the damage of optic nerve and reduces intraocular pressure.

Triphala: Triphala is another herb used in Ayurveda to treat this problem. It is usually used as an eyewash. It also reduces intraocular pressure and prevents vision loss. The herb also possesses anti-inflammatory properties that protect the optic nerve from damage.

Amla (Phyllanthus emblica): It is also a beneficial herb that manages and treats Glaucoma. It contains Vitamin C and has antioxidant properties protecting the ocular tissue, optic nerve, and retina.

Take Away

Ayurveda is one of the most effective ways to treat Glaucoma. However, it is always advisable to consult an Ayurvedic specialist before going for any of these herbs. Some lifestyle changes and exercises along with Ayurvedic treatment will help a person to gain better result.

Glaucoma - How Can Ayurveda Avert It?

The most common vision problems are shortsightedness and farsightedness. Shortsightedness is when a person sees close objects clearly while distant objects appear blurry. It is more common than farsightedness and affects about 70% of the Asian population.

When there is a refractive issue, the prescription usually has a plus/minus with it and also a number. A  minus  symbol is used to represent shortsightedness; the greater the number of the glasses, the higher the shortsightedness. High myopia is a more severe form of shortsightedness where the power is -6.0 or higher.

Symptoms: 

As mentioned, the person will be able to see nearby objects but will have difficulty seeing far off objects.

Difficulty reading signs and boards
Squinting
Straining to reduce the strain on the eye
Tired and fatigue due to this eye strain, especially when in constant move like playing sports or travelling
How it happens?

Vision can be explained by a physical process where light passes through a lens and falls on the retina in the posterior portion of the eye where it forms an image. This is then sent to the brain where it is read and interpreted as a particular object. When the lens becomes elongated, the image that is formed is distorted in that it is formed in front of the retina and not on the retina. Though it gradually settles down with adulthood, in most cases, it progresses and requires corrective lenses. The corrective lenses ensure the image falls on the retina and visual perception is improved.

Treatment:

Corrective glasses are the most commonly used measure for nearsightedness. The lenses could be used either as spectacles or as contact lenses.
Laser surgery can also be used to correct the problem. A thin layer of the cornea is removed and the image formation is corrected.
Artificial intraocular lenses are also being used to treat this condition. They work like contact lenses and may need periodic replacement.
The most common technique, especially for high myopia is the use of surgery to correct the problem. This is a one-time correction and is a more durable solution than the earlier mentioned options.
Appropriate calculations are done to identify the lens to be used so that proper vision is restored.
Complications: 

Though not common, retinal detachment and variable postoperative refractive error can occur during the surgery.
It is very important to set realistic expectations with the patient in terms of what to expect before, during, and after surgery. If only one eye is going for repair, the chances of mismatch in vision could be present in the early stages. Being clear about what to expect will help in successful correction.

Myopia or Nearsightedness - How It Can Be Treated?

Visual impairment is a decreased ability to see to a degree that causes disabilities or problems, not fixable by usual means, such as glasses. Loss of vision may be acquired and develop suddenly. It may affect one or both your eyes.

What Causes Loss of Vision/Disability?

Loss of vision and disability can result from the following  

Clouding of normally transparent eye structures

Abnormalities in the retina

Abnormalities in the nerves carrying visual signals to the brain from the eyes

Changes in vision may also occur due to conditions like glaucoma, macular degeneration and diabetic retinopathy. 

Can Psychological Rehabilitation Help Manage Visual Impairment?

Vision loss and disability often interfere with one s functional ability in everyday tasks. Sometimes, the disability may be so devastating that it affects a person s mental health and behaviour. Psychological Rehabilitation is designed to help such visually impaired people deal with disability or impairment. 

Psychological rehabilitation involves a wide range of methods that aims to restore functioning after loss of vision, just as physiotherapy restores functioning after an injury or stroke. The program allows patients to continue living independently and maintain their quality of life despite vision loss. 

Complete or partial loss of vision can jeopardize one s career   you may not be able to continue with your job due to the disability.  Many people suffer psychological and physical challenges, which force them to escape the outside world. Psychological rehabilitation helps in the following ways  

Helps individual understand and accept the disability, and find ways to cope with it

Motivates them in to keep trying

Cope with the pain and depression

Overcome feelings of fear or despair

Prevents the person from sinking into a state of self-pity, which may hinder recovery

Rehabilitation Psychology adopts a holistic and expansive approach to treat visual impairment.
