How to Improve Eyesight

Vision is one of the best gifts granted to us. We tend to take this for granted. When our eyesight starts giving trouble that is when we realize its value. Like exercise is essential to maintain a healthy body, the same is true for the eyes too.  The eyes can be affected by many problems astigmatism, color blindness, cataract, conjunctivitis, glaucoma and various others. Many of them would have to be treated with oral medication, surgeries or other methods like use of external aids such as spectacles and contact lenses. Having said this it is also true that many types of eye problems can be avoided to a large extent by taking care of the eyes and many problems can be corrected with methods used to improve eyesight. Blessed are those who have good Eye Sight. But the others need not worry as eyesight can be improved to a certain extent by following some simple tips. Some eye exercises which would help in distressing the eyes and improve eyesight are given below:

1.  Sit in an upright position and rub your palms till they become warm and then hold it against your closed eyes. This will help in relaxing the eyes. Practice deep breathing while doing this exercise. Repeat it a number of times.
2.  Rolling your eyes clockwise and anti-clockwise helps the eyes. Remember to blink in between every repetition.
3.  Focus on an object close to you for sometime and then look at an object that is beyond it. Now again focus on the object close by. This helps in focusing on a close object, shifting focus and then again focusing close by.
4.  People who tend to watch too much of television or those who work long hours using the computer also face eye problems. It is important to look away for sometime every half and hour and focus on some object far off. This reduces the strain on the eyes.
5.  A healthy diet also plays an important role in shaping your eyesight. A diet rich in Vitamin A, C and E helps in reducing the chances of contracting cataract or being affected by eye problems like macular degeneration.

If the exercises are done regularly and a balance diet is maintained one can to a large extent maintain good eyesight and improve Eye Sight that has just started giving trouble. The exercises mentioned do not consume much time and can be accommodated in any busy schedule. A little time spared for your eyes will go a long way in having good eyesight.

Eye Care & Vision Problems : What Is Done in an Eye Exam?

Cornea Abrasion

The cornea is the outer most transparent portion of the eye which works mostly as a protective shield to the iris and pupil. A cut or scratch in the cornea is known as an abrasion. Corneal Abrasion can happen due to various reasons such as scratch from fingernails, foreign objects such as metal shavings or dirt affecting the eyes, overexposure to UV rays, wearing contact lenses for long period of time, brushes used for makeup and many such similar factors can affect the cornea.

But the cornea usually takes care of small abrasions on its own. The healthy cells take necessary action and slide themselves over and cover the injured portion so as to avoid any further damage to the cornea and prevent any kind of infection that is likely to affect the eye. Certain things can be done at home itself so as to avoid corneal damage.
1.    Rinse your eye well with water.
2.    Keep the eyes closed for sometime. Do not rub.
3.    Artificial lubricants that make your eyes tear are good.
4.    Over the counter medicines for pain would help but if the pain persists even after one dose it is best to consult a doctor.
But in case the abrasion is too deep, the healing process takes much longer and in the meantime the person would experience symptoms like pain, blurring of vision, spasm in the eye, redness of the eyes, tearing and also extreme sensitivity to light. If this happens then one should not wait for the cornea to heal on its own but seek professional help. Antibiotics and cycloplegics would be used to treat the problem. Seeking medical help would be the solution when you experience eye pain without any significant problem, blurring or loss of vision and such other problems. Sometimes the wound can be so bad that a corneal transplant can be the only solution.

Opthalmoscopes are used to determine corneal abrasions but a better option would be slit lamp microscopes which give a more magnified view of the problem. Evaluation can be better with the slit lamp microscope. It is important to let the doctor know all the treatment and medication that has been taken in advance. Corneal Abrasions can happen to anyone anytime but those who are involved in work such as welding and contact lens wearers are more at risk. One can take precautionary measures at times. Wherever possible it is important that the eyes are shielded well. In case a corneal abrasion still happens seek medical help at the earliest so that the vision is not affected.
