Common mistakes wear glasses

Speaking from lenses feature, glasses that regulate amount into the eyes
of light, increased Visual acuity, eye protection safety and the role
of the clinical treatment of eye disease, caused by refractive errors
and refractive anomalies associated with headache in children Arabists
patients, after wearing cheap ray ban sunglasses
can be treated. While the glasses feature, in addition to its lens
matching constitute a glasses wearing in people's eyes to the bracket
things, it also has a beauty, decorative.
100 degree eyeglasses
Some people believe that the lower degrees of myopia or myopic people,
belong to the "pseudo myopia", and simply without eyeglasses. Concern
was also expressed that, if they were false myopia, once the glasses may
actually become true myopia.
Experts point out that, as long
as Satyriasis, optometry myopia was measured after, even if only 100
degrees, that is, "true myopia", the glasses in a timely manner. For
those who have myopia, with glasses to avoid the further deterioration
of vision, myopia will not darker, more false myopia and therefore
become true myopia is not an issue.
What is myopia
Is refractive myopia. In the context of refraction static, distant
objects not in retinal, which formed before the retinal focus, resulting
in Visual distortion, resulting in blur distant objects.
Myopia category:
1. in accordance with the level of myopia ⑴ 3.00D, referred to as mild
myopia. ⑵ 3.00D~6.00D by moderate myopia. C more than 6.00D for high
myopia, pair plead illness rational myopia.
2. in accordance
with the ⑴ refractive components of axial myopia, is caused by excessive
development of anterior-posterior axis of the eyeball. ⑵ curvature
myopia, is caused by corneal or lens surface bends through strong. ⑶
Refractive his brash myopia was caused by a refractive interstitial high
refraction rate.
3. false myopia, also known as regulation
of myopia. Is by far the control did not relax. It and the change of
refractive components of true myopia is essentially different.
A bad eye that too Ray ban sunglasses
Anisotropic exists some problem is what we usually mean by poor
eyesight, even poor eyesight of both eyes in more than 250 degrees. But
these people often have an eye sight is better, so reluctant to
eyeglasses. But in fact, the effects of poor eyesight on vision health
is equivalent to one foot wearing high heels foot ware platform shoes
was very negative, are also prone to eye fatigue and even other
injuries.
After the glasses is not always necessary to wear
Was also equipped with the myopic lens for beautiful and is not often
worn, but are worried that such an approach would add to the myopia.
However expert they reassured, because myopia glasses wearing time
myopia is deepening is not decisive. In General, if we look at something
(such as watching something more far) feel is hard enough, they are not
clear, will have to wear glasses, if you see when reading clearly could
not wear. General principle to eyes as clear and not feel fatigue
prevails.
Long-term wear "color" most have eye trouble
Experts say that myopia not only among healthy population in order to
beautiful and wear "color contact lenses" (commonly known as color
film), this is discouraged, because there are a larger number of colors
within color contact lens, the light is not normally passed to the eye,
plus special lens structure, larger than the ordinary contact lenses eye
hazard. If this is the myopia, is more do not select the degree of
color slide, prefer ordinary invisible Ray Ban 2140 Sunglasses,
because there are number of color films both assume beautifying the
eyes bear the function of vision correction, make the thickness and
pigment more complex, more discouraged. |
