Eyes are the most precious organs of our body, without them, there will only be darkness in our life devoid of all colours. It is very important to maintain good eye-sight and to take good care of our eyes’ hygiene. It is prudent to get our eyes checked regularly so that we will always be ready to keep them glowing to perform well. The most common eye problems are Myopia, Hyperopia, Astigmatism and Presbyopia.
Myopia
Myopia or Nearsightedness is a vision condition affecting about 1/3 of the population. Nearsighted people can see near objects clearly while the distant objects remain blurred to them. The image of an object is not focused correctly on the eye as the eye ball is slightly longer than usual from front to back. The sign of Myopia is difficulty in seeing distant objects, like that of highway signs, TV screen and etc. Eyestrain or eye fatigue while driving is also one of the symptoms.
Hyperopia
Hyperopia or Farsightedness is a vision condition affecting about 1/4 of the population. People with Hyperopia have difficulty seeing objects that are up close, but are able to see distant objects well. The image of the object is not focused correctly in the eye as the eyeball of a farsighted person is slightly shorter than normal.
Young people with moderate hyperopia are more able to see clearly. Their natural lens are more able to accommodate to increase in focus ability. However, beginning at about 40 years of age as the eye gradually loses the ability to accommodate, blurred vision from hyperopia often becomes more apparent. Common signs of farsightendness includes:
- Difficulty in concentrating and maintaining a clear focus on near objects.
- Eye strain, fatigue and/or headaches.
- Aching or burning eyes after sustained concentration.
- Blurry vision for viewing distant objects.
Astigmatism
Astigmatism is a vision condition which prevents the image of an object from focusing accurately on the retina. As a result, vision remains blurred at all distances. This happens when the cornea (the front surface of the eye) is slightly misshapen. Astigmatism may accompany near sightedness or farsightedness. People with mild astigmatism will experience headache, eyestrain, fatigue or blurred vision at certain distances, while those with severe astigmatism will usually have blurred or distorted vision.
Presbyopia
Due to aging, it is common that almost everyone will suffer a gradual loss of flexibility in the natural lens of the eye. This will result in one not being able to carry out simple chores like reading, working on the computers and etc. It can start as early as 40 years old. This is an age related process known as Presbyopia. Anyone suffering from Presbyopia will experience one or all of the following symptoms. While one may be able to cope with it for a short term, the condition will get worsen if not address earlier.
- You will probably find yourself holding books, newspapers or product labels further away in order to read them clearly.
- You might experience difficulty while performing near tasks.
- You might face difficulty when reading in dim light.
