General Eye

Hyperopia:

1,
Definition: When the eye adjustment Still, the parallel light through the eye after the inflection focus on the retina Oakley Split Jacket Transitions Solfx sunglasses, it is not external objects on the retina into a clear images.

2,
Clinical manifestations:

(1)
Visual impairment: loss of a degree by hyperopia and age (adjustable power) to decide

(2)
Visual fatigue: for hyperopia need to be adjusted, whether near or far to see, so often in recent operations appear blurred vision, eye swelling, heavy eyelids, eye pain or frontal, temporal pain and other symptoms of visual fatigue; adjustment can cause spasm, showing a state of pseudo myopia

(3)
Esotropia: hyperopia depending on the material adjustments as needed to address those who teach large, based on the close relationship between regulation and set, then too much excitement within the rectus muscle, a long time showing the status of esotropia

(4)
Fundus changes: no change in the general hyperopia eyes more, but moderate or more, every disc change the symptoms appear, such as congestion, swelling, optic neuritis, also known as pseudo-

(5)
Amblyopia: a high degree of hyperopia in children can lead to the cessation of visual development Oakley Scalpel Sunglasses Polished Black, to form the visually impaired

(6)
Microphthalmia: a high degree of hyperopia, the eye small, eye-like collapse was

Myopia:
1,

Definition: When the eye adjustment Still, the parallel light through the eye focuses in front of the retina after the inflection, it is not external objects on the retina into a clear images.

2,
Clinical symptoms:

(1)
Vision: far visual acuity

(2)
Visual fatigue: mild myopia often unconsciously, but there are also complained of headaches and eyestrain who was due to myopia at near when less or no regulation, but still set in order to maintain binocular single vision, so the regulation and collection function is not coordination, then, as the fatigue caused by muscular

(3)
Eye position: Because of the above regulation and function of the lack of coordination geometry, myopia prone exophoria

(4)
Fundus: low to moderate myopia fundus changes generally does not appear Oakley Jawbone Transitions Solfx Sunglasses, there is a high degree of myopia, retinal degeneration may

(5)
Narrow palpebral fissure (squinting): To make the focus of the eye becomes deep, unconscious eyes narrowed to about

(6)
Exophthalmos: high myopia, due to axial elongation, the exophthalmos

(7)
High myopia, sometimes complicated by vitreous degeneration, vitreous opacity, net choroidal atrophy, choroidal hemorrhage, retinal detachment, complicated cataract and other complications

Presbyopia (Flower):
1, definition: the lens with age and less elastic, so the near point gradually farther away, as well as near objects look clear, that barriers to close operations occur, this condition is called presbyopia.

2, clinical symptoms:

(1) difficulty reading small print

(2) eye fatigue after reading

(3) headache after close work cheap oakleys, the eyes have a sense of grit

(4) difficult to read in low lighting

Astigmatism:
1, Definition: When the eye adjustment Still, the parallel light by the eye after the inflection, because the refractive power of different refractive meridian system, causing a different degree of focus, it can not focus on the retina, forming, but formed at different distances two focal line, the distance between the two focal lines representative of the degree of astigmatism. Presented by the retina is only a diffuse ring or line, so patients either look away or look at a sense of the past are blurred.

2, clinical symptoms:

(1) mild astigmatism may have no feeling, between operations in the sense of near vision eye fatigue

(2) whether, as the distance a little weight, are vague sense, the patient often the eyelids half closed the gap into the habit in an attempt to make objects look clearer

(3) vision loss, and often seems to be ghosting

(4) visual fatigue: astigmatism adjust every attempt to overcome blurred vision, but can also compensate for different radial adjustment of the different refractive status, but can easily lead to regulation of visual fatigue, feeling the weight of the head oakley sunglasses, eye swelling tears and so on. The severity of symptoms is not necessarily proportional to the degree of astigmatism

(5) amblyopia: more common in a high degree of astigmatism, especially in hyperopic astigmatism, because to see near or far are not clear, visual lack of exercise. Prone to amblyopia, strabismus followed by a tendency to have occurred
