1.2.4 explaining implications of condition

Question 1

presbyopia

Answer 1

1. this is why people become more longsighted as they age

presbyopia is where due to normal age related changes

the lens side th eye comes less flexible and looses its ability to focus at near.

it is why most people need reading glasses past 40

Question 2

myopia

Answer 2

often called short sightedness. myopia causes distant objects to appear blurred. The eye ball is too long for the normal focusing power of the eye -

focusing problem the re light normally travels through the eye and focuses on the light sensitive layer - retina.
in myopia the light focuses too far forward and in front of the retina causing things to be blurred in distance.

easily corrected with lenses which focuses light properly.

Question 3

hyperopia

• struggle to see things upclose
  light focuses behind retina lsl
  due to eyeball being too weak or too short.
  causing things to look blurred

most children have hyperopia which gets better on it own with age.

Answer 3

1. Long sightedness is the inability to see near objects as clearly as distant objects, and
   the need for accommodation to see distant objects clearly.
2. Long sight is when your eyeball is either too short, or the cornea at the front of the your is not curved steeply enough. If you are long-sighted you have to focus more to see things clearly than you would if you were perfect sighted. It affects your vision of things that are far away as well as things that are close to you, but is more noticeable for things that are close to you
3. You find it more difficult to see clearly objects that are close to you. For example, words on a page or your phone screen may seem blurred.

Question 4

astigmatism

Answer 4

might notice blurring or distortion

easily corrected with gas or special topic lenses that focus light correctly

Question 5

amblyopia

Answer 5

• referred to as lazy eye which is a childhood condition were the vision doesn’t develop correctly usually in one eye.

-Lazy eye or amblyopia may be caused if a young child needs very strong glasses, has one eye that is significantly more short-sighted or long-sighted than the other, or has a squint (where the eyes are not looking in the same direction). This means that the sight in the affected eye or eyes does not develop properly.

Question 6

kertaconus

Answer 6

eye condition in which the cornea the clear dome shaped part of the front of the eye progressively thins causing a cone shaped buglge to develop.

symptoms- include fq change or blurring of vision , double vision in one eye, obj both far and near look distorted , bright lights have haloes, light streaking, ghost images

Question 7

rd

Answer 7

At the back of the eye there is a layer that is greatly responsible for your vision, called the retina. If you imagine the retina as wallpaper, in your eye there appears to have been a tear, a portion of the retina broken off. This is now starting to peel off and is causing a curtain to come over your vision. This wallpaper needs to be reattached ASAP to restore vision and prevent any further loss.

Question 8

glaucoma

Answer 8

ithin the eye, there is a certain amount of pressure. This can be either high or low, just like with blood pressure. In the case of glaucoma, this is generally when the pressure in the eye becomes higher than it should & starts to damage the optic nerve, the nerve that connects the eye to the brain letting you see. In most cases glaucoma sufferers will experience no symptoms until significant damage has occurred.

Question 9

cataract

Answer 9

cataract is a clouding of part of the eye called the lens. Vision becomes blurred or
dim because light cannot pass through the clouded lens to the back of the eye.

Question 10

bleh /dry eye

Answer 10

ry eye occurs when your eyes don’t make enough tears, or your tears evaporate too quickly. This can make your eyes feel scratchy or irritated, and in severe cases may temporarily make your vision blurry.
Dry eye is more common in women and in people aged over 65. This is because as you get older, your eyelids are not as effective at spreading your tears across your eyes when you blink. Also, the meibomian glands in your eyelids, which produce the oily part of your tears, become less effective and may become blocked. This is a condition called blepharitis.

Question 11

bleph

Answer 11

1. blepharitis is a condition in which chronic (i.e. long-term) inflammation of the eyelid margins causes symptoms of eye irritation. Sometimes there are no symptoms. There are two types of blepharitis, which sometimes occur together:
   - Anterior blepharitis, which affects the outside front edge of the eyelids (near or among the roots of the eyelashes)
   - Posterior blepharitis, which is also called Meibomian Gland Dysfunction (MGD), results when the condition affects the inside rims of the eyelids (just behind the eyelashes) which contain the meibomian glands. (The meibomian glands produce a thin layer of oil which normally prevents the tears from evaporating too quickly; if they are inflamed, this mechanism does not work properly)

Question 12

DR

Question 13

AMD

Answer 13

the back of the eye there is a layer that is greatly responsible for your vision, called the retina. On the retina, there is this small area called the macula. This is responsible for your detailed, central vision and with macula degeneration, there is a slow deterioration of it, causing some blurred vision and distortion in the vision. It is a very common condition in those above the age of 70 & is something we monitor.
