Through Other Eyes

Ever wondered what it would be like to see through another person's eyes?

In these images we have simulated the picture seen by people with some of the common eye problems (click on the small pictures to enlarge them).

Long and Short Sight

 Long Sighted - The person sees things clearer at distance than at near. The light through the lens focusses behind the eye so we need to add lens power to the eyes to enable clearer vision.  Note the blurry "No Parking" sign.

 Short Sighted - The person sees things clearer at near with a blur in the distance. The light through the lens focusses inside the eye (not on the retina) so we need to subtract lens power to the eyes to enable clearer vision. 

 

Blurry Vision Caused by Astigmatism and Cataracts

 

blur.jpg (24371 bytes)

 Astigmatism - A condition where the person’s sight levels are in constant conflict for distance and near with the eye reaching a point of equal blur where neither distance nor near is perfectly clear. Note blurr and distortions.

cataract.jpg (27446 bytes)

 Cataract -A condition which develops when the crystalline lens of the eye begins to develop barriers stoping light from getting through it. Note the blurr but no distortions.

 

Macular Degeneration

 Macula Degeneration - The condition when the central area of our retina called the "macula" becomes inflamed due to some vascular dysfunction and if not treated immediately can lead to permanent blindness.  If its function is lost what  you would notice is that every time you tried to look directly at something there would be a shadow or blackspot directly in front of it obstructing you seeing it. Note loss of some cars in centre of vision field.
 

Retinal Detachment

 Retinal Detachment Occurs when retina lifts off the back of eye. Note loss of sight of the bus and distortions at edge of field of view.
 

Floaters

 Floaters - Floaters are tissue remnants located in the vitreous body. They will often move after a vigorous blink. Patients view.
