	Blind spots
		Because of this, you should have a "blind spot" (actually two, one for each eye), a place pretty much in the middle of what you can see where you can't see.
		Maybe the blind spot for one eye is at a different place than the blind spot for the other (this is actually true), so you don't notice it because each eye sees what the other doesn't.
		The spot disappears because it falls on the optic nerve head, the hole in the photoreceptor sheet.

		Directly behind the pupil is a small yellow-pigmented spot, the macula lutea, in the center of which is the fovea centralis, the area of greatest visual acuity of the eye.
		In general the eyes of all animals resemble simple cameras in that the lens of the eye forms an inverted image of objects in front of it on the sensitive retina, which corresponds to the film in a camera.
		Blindness caused by cloudiness or scarring of the cornea can sometimes be cured by surgical removal of the affected portion of the corneal tissue.

		Vertebrate retina are layered with neurons in front of the photosensitive cells, mollusk retina are reverse with photosensitive cells in front of the neurons, this provides mollusk with no blind spot and may provide clearer vision, but may also provide slower retinal recycling and thus slower vision refeshing and motion detection.
		The blind spot is a point on the retina where the optic nerve pierces the retina to connect to the nerve cells on its inside.
		In anatomy the orbit is the cavity or socket of the skull in which the eye and its appendages are situated.

	Professor criticises medicine's 'blind spot', patients' symptoms
		Professor Michael Sharpe highlights medicine's 'blind spot' in dealing with symptoms that are not just expressions of disease.
		These include the many cancer patients who also suffer from depression, the one third of medical outpatients whose symptoms are not to be explained by disease, and patients with controversial syndromes such as chronic fatigue syndrome or ME.
		He says this 'blind spot' is a result of relegating aspects of medicine not associated with diagnosing and treating disease to the pre-scientific 'art of medicine', or even to complementary and alternative medicine.

		Since pathology and anatomy are so closely related, you'll find that this section also contains descriptions of the most common causes of visual loss: cataract, glaucoma, macular degeneration, and retinal detachment, as well as many other common eye diseases such as conjunctivitis (pink-eye), presbyopia ("arms getting too short"), floaters, and iritis.
		This hole (anatomically it's really more like a window with a screen over it) in the sclera is our natural blind spot (one per eye) and it's "filled" with the head of the optic nerve, which is just like a bundle of threads (1.5 mm in diameter).
		When the pressure inside the eye rises (glaucoma), this spot also happens to be the weakest spot in the eye, so the optic nerve literally is crushed, and it dies.
