The art of vision......experience the extra time and care we take

Emmetropia: The Eye with normal vision.

 

Light from a distant object (e.g. Motorway sign) is first partly focused by the cornea and then finely focused by the natural crystalline lens behind the pupil and brought to a sharp focus on the retina. The natural focusing muscles of the eye are relaxed and distance vision is clear.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Myopia: The Short-sighted eye.

 

Light from a distant object is focused by the cornea and crystalline lens to a point in front of the retina so the image falling on the retina is blurred. The natural focusing muscles of the eye are relaxed and distance vision is blurred.Using the focusing muscles to focus the image only makes the image more blurred.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Hyperopia: The Long-sighted eye.

 

This is the opposite to short-sightedness; light from a distant object is focused by the cornea and crystalline lens to a point behind the retina so the image falling on the retina is blurred.

The natural focusing muscles of the eye are relaxed and distance vision is blurred.

 

Using the focusing muscles to focus the image makes the image clear. Many people who have a small amount of long sight automatically focus their eyes and are never aware that their vision is anything less than perfect.

 

However people with higher amounts of long sight can suffer headaches and intermittent blurred vision as their eyes feel the strain of the constant focusing effort. If the long sight is greater again it can cause a squint. (This is when one eye turns into the nose when looking straight ahead)
