|---|---|---|---|---|---|
| show | when light rays pass from one medium to another,their velocity or speed of transmission changes, and the rays are bent or refracted.
🗑

| show | the ability of the eye to focus deferentially for objects of near vision (less than 6 m, or 20 feet)
🗑
|

| show | the image formed on the retina as a result of the refractory activity of the len
🗑

| show | eye is able to accommodate properly. visual problem may result
-from lenses that are too strong or too lazy (overconverging or underconverging, respectively).

🗑
|
||||
| show | near sightedness. the image normally focuses in front of the retina. a person can see close object without difficulty. correction require a concave lens which causes the light reaching the eye to diverge.
🗑
|
||||
| Hyperopia | show 🗑
|
||||
| show | irregularities in the curvatures of the lens and/or the cornea lead to a blurred vision problem. Correction--cylindrically ground lenses which compensate the inequality in the curvature.
🗑
|
||||
| show | difficulty in focusing for near or close vision due to decreasing of elasticity of the lens. can be tested by near point of accommodation.
🗑

| A convex lens, like that of the eyes produces an image that is upside down and reversed from left to right. Such an image is called a________image | show 🗑
|

| during distance vision, the ciliary muscle is______, the ciliary zonule is_____, the convexity of the lens is_____and light refraction is _______ | show 🗑
|
||||
| During close vision, the ciliary muscle is _______, the ciliary zonule is ________, lens convexity is _____, and light refraction is ________ | show 🗑
|

| show | auricle (pinna), external acoustic meatus,stapes
