Eye sight and Television viewing - How it affects?

Television Viewing

Television will not hurt the eyes if you have a fairly large screen, do not keep the room in total darkness, do not sit too close to the set or at an angle, and do not watch steadily for extended periods. It can be wise to be arbitrary about children's viewing, setting an hour as the limit for Swimming Rarely does swimming cause ear trouble unless there is a nose, sinus, or throat infection. Learning how to breathe in through the mouth and out through the nose during swimming is a helpful preventive measure. In the case of a perforated eardrum, however, you should have your doctor's permission and advice before going swimming. 

Once in a while, an eardrum may be perforated by the pressure of high diving; pain, and sometimes bleeding, will result. If you see a doctor immediately, there will probably be no permanent harm from such an accident. Deafness There are many degrees of hearing impairment. Mild hearing loss may go unnoticed. When the loss is great enough to produce some difficulty in communication, the condition is commonly called "hard of hearing." When so much hearing ability is lost that a loud voice, even a voice amplified by a hearing aid, cannot be heard, the condition is called deafness. 

Hearing impairment may stem from an inner ear problem; essentially, this is nervedeafness. Often, the impairment is of the conductive type in which there is no nerve involvement but rather some defect in the conduction of sound waves in the outer ear canal or the middle ear. An infection, injury, or congenital deformity may close the ear canal, and the canal may need surgical reconstruction. If an eardrum has been partially destroyed by infection, plastic surgery may repair it. If the middle ear bones are damaged by infection, corrective surgery may help.

Otosclerosis, a common form of impairment, involves the stapes, one of the middle ear bones. Because of overgrowth of bone, the stapes cannot vibrate properly and so is unable to transmit sound waves. An operation to mobilize the stapes has restored hearing for many people. And other surgery may be used when the mobilization operation is not suitable. 

Many types of hearing impairment can be overcome to a marked degree, even almost completely, with hearing aids. It is tragic to think of all the people who lead handicapped lives because they believe that others will make fun of them if they wear an aid. If this was ever true -and we doubt it-it is certainly no longer true with aids that bear no resemblance to trumpets. 

Modern devices are well designed and effective when properly chosen. Since various hearing impairments differ, it is important to find an instrument suited to the wearer's specific needs. A specialist, not a salesman, can give you the right advice.  Consist of having your own and your children's hearing tested at regular intervals and of seeing your doctor the moment you or a child feel any pain, note any ear discharge, experience any unusual buzzing, ringing, or pressure in the ear, or become aware of any seeming diminution of hearing acuity. 

Eye sight problems and cure

Fortunately, eye glasses have become so "glamorized" that resistance to them is disappearing. For people in special occupations-actresses and others-who would find ordinary glasses a handicap, contact lenses which fit directly over the eyeball are often useful. 

They are expensive, not always easy to insert, and may be tolerated for only limited periods. Contact lenses, however, are constantly being improved, and your eye doctor can advise about their suitability for you. Exercises for the eyes may be helpful under some circumstances. They should not, however, be used without first consulting an eye doctor. 

There can be grave danger when exercises are used indiscriminately to try to correct vision difficulties that in reality may stem from glaucoma or some other potentially serious disorder that needs attention without delay. An ophthalmologist-an eye specialist who has had medical school and additional postgraduate training in the field-has the background to check not only for eye defects and problems per se but also for any systemic problems that may show up through the eyes.

 It is usually important to see such a specialist whenever you believe you have an eye problem. His examination and diagnosis can make a valuable contribution to maintaining your general health as well as improving your eye health. He can prescribe not only suitable glasses but also, when appropriate, helpful corrective eye exercises.
