1)how often should I check my eyes?<\/b><\/div>\n
 <\/div>\n
The screening of the eye at regular intervals(although not every<\/div>\n
six months ,every year) not only can detect in time any<\/div>\n
diseases that reduce vision, but also to identify chronic problems<\/div>\n
health start from other organs and systems.<\/div>\n
 <\/div>\n
2)What is strabismus?<\/b>

<\/b><\/div>\n
Myopia is a common refractive error of the eye, due to<\/div>\n
anatomical disproportion of. Because of this, the rays of light (the<\/div>\n
\u201cidol\u201d which is formed) are not concentrated in the retina,<\/div>\n
as it is normal, but at some point in front of him. For<\/div>\n
for this reason, the near-sighted cannot see clearly the objects that<\/div>\n
they are away, and has not been a problem in the objects that are<\/div>\n
close.<\/div>\n
 <\/div>\n
Ways to deal with myopia:<\/div>\n
 <\/div>\n
(a)glasses that are diverging lenses.<\/div>\n
 <\/div>\n
b)contact lenses of different types(soft, \u03b7\u03bc\u03af\u03c3\u03ba\u03bb\u03b7\u03c1\u03bf\u03b9).<\/div>\n
 <\/div>\n
3) Up to what age is rising strabismus?<\/b><\/div>\n
 <\/div>\n
Myopia is stabilized around 20 years ,but lately we are seeing a<\/div>\n
voltage the age limit for the stabilization to dolly up to 28 years.<\/div>\n
 <\/div>\n
4)<\/b> What is hyperopia<\/b>;<\/div>\n
 <\/div>\n
Hyperopia is a condition opposite of myopia. In<\/div>\n
this case the eye is very small. Thus, the images are not<\/div>\n
formed upon the retina, but at some point behind<\/div>\n
him. That's why the people can't see objects clearly<\/div>\n
situated close to him ,while he has no problem with those<\/div>\n
located away from him.<\/div>\n
 <\/div>\n
Addressing the problem is with positive lenses.<\/div>\n
 <\/div>\n
5) when it grows hyperopia;<\/b><\/div>\n
 <\/div>\n
Hyperopia occurs in childhood and continues into adolescence.<\/div>\n
Usually accompanies \u03c3\u03c4\u03c1\u03b1\u03b2\u03b9\u03c3\u03bc\u03bf\u03cd\u03c2 and after the restoration of strabismus, the<\/div>\n
people abandons his glasses.<\/div>\n
 <\/div>\n
6) What is presbyopia?<\/b><\/div>\n
 <\/div>\n
Presbyopia is called the difficulty of a clear focus in close-ups<\/div>\n
objects .Presbyopia occurs after the age of 40 years and<\/div>\n
completed in 58 years of age .<\/div>\n
 <\/b><\/div>\n
7) At what age is shown the presbyopia?<\/b><\/div>\n
 <\/div>\n
Presbyopia is a form of hyperopia, that is a good remote but not<\/div>\n
good close-up vision. In women occurs more early, around<\/div>\n
forty-against average, while the men three years later, again by means of<\/div>\n
condition. As the years go by presbyopia will increase continuously until the<\/div>\n
age 55 years old so and stabilized. then begins the<\/div>\n
presbyopia is in need of help and in distant vision.<\/div>\n
 <\/div>\n
8) I Got a bit of glass from a drummer, and I can see there is a problem?<\/b><\/div>\n
 <\/div>\n
YES, there is. The glasses that have not passed through any quality control<\/div>\n
it is of low quality, and value, of course. Prolonged use of the<\/div>\n
can lead to premature increase of presbyopia, etc. There is no<\/div>\n
reason to risk your eyesight. The more insurance funds IKA<\/div>\n
TEBE PPC BANKS OTE POST offices etc. providing free examination by an ophthalmologist<\/div>\n
(so much better than the drummer). And not only that but also provide<\/div>\n
every 4 years for the purchase of frame and crystals 100euro per person.<\/div>\n
 <\/div>\n
9)What is the \u03c0\u03bf\u03bb\u03c5\u03b5\u03c3\u03c4\u03b9\u03b1\u03ba\u03ac glasses, because it's expensive?<\/b><\/div>\n
 <\/div>\n
A \u03c0\u03c1\u03b5\u03c3\u03b2\u03cd\u03c9\u03c0\u03b1\u03c2 need glasses for near and far can<\/div>\n
has clear vision close (35\u03b5\u03ba\u03b1\u03c4.) and far away (6 meters).Intermediate<\/div>\n
distances are unclear. The \u03c0\u03bf\u03bb\u03c5\u03b5\u03c3\u03c4\u03b9\u03b1\u03ba\u03ac glasses provide sharp vision and<\/div>\n
these distances because they have a lot of outbreaks. The adjustment can<\/div>\n
to keep five weeks. But then the vision will be clear<\/div>\n
everywhere ,I won't forget your glasses since you won't shoot at all. The<\/div>\n
cost is not terrible if you think that you are buying only a skeleton<\/div>\n
instead of for two you needed to know before plus the assistance of the security<\/div>\n
your.<\/div>\n
 <\/div>\n
 <\/div>\n
10) What is astigmatism?<\/span><\/b><\/div>\n
 <\/div>\n
Astigmatism is a refractive error in which the light<\/div>\n
enters the eye is not focused to a point on the<\/div>\n
retina, but in a couple of vertical lines between them. This is as<\/div>\n
the result that the patient sees distorted and distant, and<\/div>\n
nearby objects. If the astigmatism is small, usually not<\/div>\n
it causes problems in vision. In the opposite case, it can be<\/div>\n
cause fatigue to the eyes, especially during the use of a computer or<\/div>\n
during the reading.<\/div>\n
 <\/div>\n
11) Maybe it's the astigmatism for a headache?<\/b><\/div>\n
 <\/div>\n
Yes it is possible. Astigmatism causes the eye to trying to<\/div>\n
focus but don't make it. This effort brings the<\/div>\n
headache. With the right medication (a pair of \u03b1\u03c3\u03c4\u03b9\u03b3\u03bc\u03b1\u03c4\u03b9\u03ba\u03ac glasses)<\/div>\n
the headaches go away and at the same time improves the vision.<\/div>\n
 <\/div>\n
12) what is the proper way of cleaning of sunglasses and optical frames;<\/b><\/div>\n
 <\/div>\n

our eyes from any damage .The solar radiation is responsible for<\/div>\n
various pathological changes in the eyes of us. It is possible the appearance<\/div>\n
wrinkle and growths on the eyelids, which may be even<\/div>\n
malignant. The sunglasses will necessarily have to bear the CE marking,<\/div>\n
namely, that the construction complies with the european requirements<\/div>\n
security. Also, you need to absorb 100% of uv radiation<\/div>\n
 <\/div>\n
14) Is it necessary to wear sunglasses if cloudy days?<\/span><\/b><\/div>\n
 <\/div>\n
When it's cloudy, the sunlight is just as damaging .Besides, the<\/div>\n
genuine sunglasses are designed to protect from<\/div>\n
ultraviolet rays UVA and UVB.<\/div>\n
 <\/div>\n
 15)What are the degrade lenses?<\/b><\/div>\n

<\/span><\/div>\n
The lenses are graduated darkness (degrade lenses) are ideal for daily driving, featuring a satisfactory darkness in the upper part, while its lowest points, being \u03b1\u03bd\u03bf\u03b9\u03ba\u03c4\u03cc\u03c7\u03c1\u03c9\u03bc\u03bf\u03b9, facilitate the vision in the area of the car.<\/span> <\/div>\n

process.<\/div>\n
 <\/div>\n
18) When do I need a thinner lenses?<\/b><\/div>\n
 <\/div>\n
When the degrees of your condition is more than 2 or 3 is good to<\/div>\n
buy thinner lenses. The \u03ba\u03bf\u03ba\u03ba\u03ac\u03bb\u03b9\u03bd\u03bf\u03b9(\u03c0\u03ac\u03c3\u03c4\u03b9\u03bd\u03bf\u03b9) skeletons are<\/div>\n
ideal to cover the thickness of the lens, while the metal or<\/div>\n
skeletons without frame (Grif\/Nylor) are not suitable for large numbers<\/div>\n
since the aesthetic result will be ugly, unsightly. Option<\/div>\n
of course, always remains yours.<\/div>\n
 <\/div>\n
19) What are polarized lenses?<\/b><\/div>\n
 <\/div>\n
The polarized lenses are specially treated lenses which<\/div>\n
inside them contain filters. Can and eliminate<\/div>\n
reflections, mainly those caused by the sun, after the<\/div>\n
rain or snow. This category of lenses for sunglasses<\/div>\n
recommended to those who lead many hours.<\/div>\n
 <\/div>\n
 <\/div>\n
20) when you need to change the \u03c0\u03bf\u03bb\u03c5\u03b5\u03c3\u03c4\u03b9\u03b1\u03ba\u03ac glasses;<\/b><\/div>\n
 <\/div>\n
Presbyopia is a condition that evolves over<\/div>\n
time, in ages from 40 up to 60-65 years of age. Starts with +0,50 degrees<\/div>\n
first, and reaches in normal cases up to +2,50 degrees in<\/div>\n
age of 60-65 years. From 40 to 50 years old, have a change in glasses<\/div>\n
every 2-3 years. After the age of 50, this change is about<\/div>\n
every 4 years.<\/div>\n
 <\/div>\n
21) What is the \u03c6\u03c9\u03c4\u03bf\u03c7\u03c1\u03c9\u03bc\u03b9\u03ba\u03bf\u03af lenses?<\/b><\/div>\n
 <\/div>\n

accordingly the brightness of the environment. Is lenses advanced<\/div>\n
technology that adapts to any lighting condition. Indoors<\/div>\n
areas ,but during the night is totally clear, while<\/div>\n
darken depending on the natural lighting in outer space. Offer<\/div>\n
100% protection from UV radiation and capable of anti-reflective<\/div>\n
coatings protect the lenses from engravings, dirt and dust.<\/div>\n
 <\/div>\n
 <\/div>\n
22) What are the disadvantages of multifocal glasses?<\/b><\/div>\n
 <\/div>\n
To achieve clear vision, the freedom of movement of the eye<\/div>\n
limited. For example, the bike will have to do with the<\/div>\n
head (and not only with your eyes) a small downward stroke to<\/div>\n
look at your hands.<\/div>\n
 <\/div>\n
Due to the optical properties of the lens, it takes time to<\/div>\n
get used to it. (From one to three days, usually)<\/div>\n
 <\/div>\n
The fields of vision in the far and in the walking distance is smaller<\/div>\n
from those of \u03bc\u03bf\u03bd\u03bf\u03b5\u03c3\u03c4\u03b9\u03b1\u03ba\u03ce\u03bd glasses.<\/div>\n
 <\/div>\n
23) What are the advantages of multifocal glasses?<\/b><\/div>\n
 <\/div>\n
The mid-term vision, which is achieved through the \u2018channel\u2019 gives you the<\/div>\n
ability of a medium-sized vision that is in no bifocals glasses.<\/div>\n
 <\/div>\n
Wear them all day and you don't have to ever take it off for you to wear<\/div>\n
other, since they improve the vision at all distances.<\/div>\n
 <\/div>\n
You don't have to there are two different glasses (close to and<\/div>\n
remote).<\/div>\n
 <\/div>\n
It is more elegant and elegant than bifocals glasses.<\/div>\n
 <\/div>\n
24) What are the anti-reflective coatings;<\/b><\/div>\n
 <\/div>\n
The antireflective coating is a treatment that is done on the<\/div>\n
ocular lenses to eliminate unwanted reflections.<\/div>\n
 <\/div>\n
Ensures greater clarity on the vision, giving up to 99%<\/div>\n
permeability of light. Anti-reflective coating is useful for<\/div>\n
everyone who wears glasses as well as improves vision at night and<\/div>\n
it offers comfort for work in front of the computer. Reduces glare,<\/div>\n
it offers protection anti-scratch. Also, the coatings do them<\/div>\n
lenses look thicker than it really is.<\/div>\n
 <\/div>\n
25) What is the Refractive Index of a lens;<\/b><\/div>\n
 <\/div>\n
It is a technical characteristic of the material of the lens that the change of the<\/div>\n
as a result of the change in the thickness. The refractive index for<\/div>\n
traditional crystal and traditional organic is about 1.5 .<\/div>\n
When you increase this number decreases the thickness of the lens.In the crystals<\/div>\n
there are lenses available, with an index of refraction of up to 1.9 and the organic<\/div>\n
up to 1.74, while the polycarbonate is available with a refractive index 1.58.<\/div>\n
 

<\/div>\n
26) What is a cataract?<\/b><\/div>\n
 <\/div>\n
Waterfall is called the clouding of the crystalline lens is located<\/div>\n
inside the eye blurring usually comes from aging while<\/div>\n
there are cases where cataracts are congenital (from hereditary<\/div>\n
case) , metabolic coming from diabetes or even<\/div>\n
traumatic.<\/div>\n
 <\/div>\n
When the haze comes from aging will be perceived about the<\/div>\n
age of 50-60 years old.<\/div>\n
 <\/div>\n
The waterfall is treated only surgically, as well as removed the lens<\/div>\n
and placed new covet lens whoever will be permanent.<\/div>\n
 <\/div>\n
27) What is the blue coatings;<\/b><\/div>\n
 <\/div>\n
The technology of blue pavers, you have a special filter<\/div>\n
absorption of the blue radiation, provides the ideal protection against<\/div>\n
the blue light emitted by all modern electronic devices.<\/div>\n
Binds about 97% of the harmful, for the vision and the health of<\/div>\n
eye ,radiation, neutralizing the feeling of visual fatigue<\/div>\n
caused by continuous and prolonged use increases the<\/div>\n
in contrast, while at the same time provides the maximum sharpness,<\/div>\n
without the annoying deformities and lesions observed<\/div>\n
original.<\/div>\n
 <\/div>\n
28) When not to use contact lenses?<\/b><\/span>
<\/div>\n
 <\/div>\n
The contact lenses give you a much better and wider vision compared with the<\/div>\n
use of glasses.<\/div>\n
However, it should not be used in any environment.<\/div>\n
When there is dust, intense dryness of the environment,<\/div>\n
chemical fumes (e.x hair spray) then it is preferable<\/div>\n
the use of the glasses to avoid problems.<\/div>\n
 <\/div>\n

<\/div>\n
29) Children's Vision...is Affected by the use of smartophones or<\/b><\/div>\n
tablets?<\/b><\/div>\n
 <\/div>\n
Of course! The continuous stay of children in interiors, in<\/div>\n
combination with the use of electronic \u03c3\u03c5\u03ba\u03b5\u03c5\u03ce\u03bd, increase the chances of<\/div>\n
occurrence of myopia.<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
