Refraction occurs when light enters (or leaves) a medium with a different (optical) density at an angle of less than 90o. The cornea, aqueous humor, lens, vitreous humor and air all have different refractive indices, so light refracts as it passes from one to the other.
3.7 Students learn to distinguish between myopia and hyperopia and outline how technologies can be used to correct these conditions. Myopia can be corrected by wearing concave spectacles or contact lenses or by refractive eye surgery. LASIK (Laser-Assisted in situ keratomileusis) involves making a very thin slice in the front of the cornea, shaping the underlying cornea using an excimer laser, then replacing the flap.
PRK (Photo Refractive Keratectomy) and LASEK (Laser Epithelial Keratomileusis) involve shaping the outer surface of the cornea using an excimer laser.



Phakic IOL (Inter-Ocular Lens) is the placement of a lens behind the cornea and in front of the iris.
Depth perception is possible because we have binocular vision - there is overlap (~ 120o) between our two eyes.
Photo pairs allow the same depth perception because each photo is taken by a separate camera, both aimed at the same point.
Stereo pairs with practice you can make the two images overlap (you will see three images - the centre one is 3-D).
The cloudy lens must be removed (either whole or after phacoemulsification with ultrasound) then replaced with an interocular lens. This dot point will be (has been) covered in practical lessons.A A  Refer to your Practical Record Book showing how changes in the curvature of a convex lens affects its focal length.

Stereo pairs with practice you can make the two images overlap (you will see three images - the centre one is 3-D).A  Placing a card between the photo pairs will allow you to see just one image.
