Eye Care – Try a new perspective

Clear vision is obtained when light coming in to a healthy eye is focussed directly on the retina.

Myopia (short sightedness):

When light coming into your eye is focussed in front of the retina.

This makes you see close things clearer without glasses, but things at a distance appear blurry. Spectacles or contact lenses may be worn for driving, watching TV or looking at the board at school.

Hyperopia (far sightedness):

When light is focussed at the back of the retina.

This makes you clearly see objects at a distance, but objects close up are blurry without glasses.

Depending on the degree of farsightedness, people expend their focussing effort to see things clearly at a distance also.

This can cause eye fatigue, headache, lazy eye or crossed eye.

Astigmatism:

This occurs when the front surface of your eye (cornea) is not perfectly round and is slightly oval in shape. Both distance and near vision are blurry. Spectacles are needed to be worn for clearer vision.

More than 75% of people around the world have astigmatism at different degrees.

Presbyopia:

As you age, you lose the ability to focus on close objects. The lens in your eyes lose elasticity, which makes it hard for you to focus at near objects.

This can be corrected with glasses. We do expect the strength of the glasses to increase over the years until it becomes stable; that is when the lens are not elastic at all.
