Many ophthalmicauthority pointed out that wearing glasses frame resin
lens is the best choice for the correction of myopia. However, for
beautiful, convenient and work needs other reasons, contact lenses seems
to be more popular. However, and other body organs, the eye cornea
needs oxygen to stay healthy. And it is to get 95% of oxygen are
dependent on the outside air, the soft contact lens oxygen permeability
value is not high, the cornea can not breathe properly, long-term
hypoxia occurs corneal edema, chronic keratitis and other eye diseases,
even cause irreversible eye damage. In this case, with a high oxygen
permeable hard contact lenses (referred RGP) came into being.
RGP has the following unique advantages:
1. High oxygen permeability surface of the eye to ensure
adequate oxygen copies, compared with ordinary Soft lenses greatly
reduce complications, is the safest to wear contact lenses, the
continuous wearing time can be up to 30 days, which is unmatched by soft
contact lenses;
(2) It is shaping effect is good, with good optical performance,
ensure that you get a clear vision, even the high degree of
astigmatism, irregular astigmatism, aphakia will get a good correction;
3 It has a rigid material, simple to use, easy care, life expectancy is much longer than ordinary soft lenses;
4. additional large number of clinical studies have shown that
it can also delay juvenile myopia development is ideal for youngsters
vision correction options.
Because of this, RGP increasingly recognized by clinicians and
patients at home. RGP Ministry of Health has now been designated as "one
hundred years" to promote the project (ophthalmology unique items) by
clinicians to conduct a comprehensive examination of each patient,
according to the inspection data tailored to give the most accurate and
scientific correction. Buy one based solely on soft contact lenses
myopia will become less and less, fitting an RGP will become a trend.
But fitting RGP should choose the regular specialist eye hospital, by a
high-tech professional doctor prescription, repeatedly tried assessed,
based on the curvature of your cornea, curvature, tailored to fit your
eye contact lenses!
RGP lenses advantages
1, good physiological compatibility, so that long-term wear RGP lenses are unlikely to cause corneal hypertrophy and edema.
2, high oxygen permeability, are unlikely to cause hypoxia and dry eye, corneal endothelial cells does not cause a change.
3, the prevention of myopia or astigmatism deepened vision correction better than soft contact lenses.
4, simple maintenance, long service life; proper care, the lens can be used for up to 2-3 years.
5, long-term use lenses cost cheaper.
6, long-term use can maintain corneal physical health, safe.
7, due to wear soft contact lenses and long-term hypoxia,
bloodshot eyes or cause neovascularization, dry eye, with poor vision
correction, eye back to health can be changed with RGP lenses.
8, another at home and abroad, according to data: RGP lenses can effectively control the growth of juvenile myopia.
life are changing the human eye, especially at a young age, with
the development of the body, the eyes are also developmental changes,
eye exams 1-2 times a year, for their eyes find a healthy guards, while
currently wear glasses to see whether it is still suitable for their own
eyes.
According Eye Hospital of Wenzhou Medical Center recently made
optometry clinic statistics show that currently on the market or fitting
of glasses out there are many cases failed, failed glasses mainly
manifested in the following:
optometry inaccurate
some parents believe that the lower the better spectacles, is
actually wrong, glasses main function is to meet the patient's daily
visual requirements, if the degree is too low, but to make patients'
daily blurred vision, causing eye fatigue, it is usually put at least
corrected visual acuity to 1.0, astigmatism correction to the fullest ,
otherwise it will easily lead to eye fatigue. Meanwhile binocular vision
to balance, so have a good balanced stereo vision and binocular
accommodative power.
glasses inaccurate
patients with out glasses IPD differences still exist, two
highly inconsistent lens optical center of the lens luminosity, etc. are
not allowed problem, so we recommend an accurate optometry glasses also
require accurate, otherwise it is equal to accurate medical diagnosis,
medication given is wrong or even harmful, it is worth the candle.
glasses frame deformation
some patients wearing a pair of glasses or even ten years in
2056, to take over when we look at time, has been severely deformed, the
deformation of spectacle frames spectacle lenses will cause the
location is not accurate, which will cause failure of glasses.

Frequent use of contact lenses should pay attention to what?
1. In off, wash your hands before wearing contact lenses to more than 20 seconds, so as to play a role in sterilization.
2. In off, wearing contact lenses can be used before and after antibiotic eye drops to reduce eye infection.
3. Remove contact lenses before going to sleep better, avoid corneal hypoxia, affect vision, increased corneal infection.
4. Soak the container, to be replaced regularly.
5. Wearing contact lenses if redness, photophobia, tearing, should immediately stop wearing a timely manner to the hospital

Talk outdoor knowledge can wear contact lenses on the plateau
1. Plateau elevation to what extent people will react?
a few people when there is less than two thousand meters of altitude sickness, but most occur at high altitudes above 3,000 meters, 3,000 meters of altitude sickness occurs is critical height.
2. Sleep at night in the highlands breath how to do?
altitude affect ventilation, people often feel relatively urgent breathing, panting badly, sleep is not practical, this is relatively normal. Suggested as possible to sleep at night in the highlands area or try to elevate the head can sit and sleep, so breathe few.
3. Just on the plateau on the oxygen okay?
First of all, do not recommend that people entering the plateau on the rush of oxygen, because it will affect the body's adaptability to climatic conditions and altitude plateau timely establishment, of course, this applies to altitude sickness relatively small class of people . If more serious altitude sickness and physical weakness, it is recommended that timely oxygen, especially at night, because that can help alleviate the symptoms of altitude sickness people, get a good rest, physical strength.
4. How to prevent skin plateau?
proposals must be in the plateau region with a high SPF skin care products, especially the face of the nose, cheekbones, ears site should be fully applied, because these parts of the skin more delicate, more sunburn and peeling.
5. Plateau wear contact lenses okay?
wear contact lenses should be noted that most cleaning problem, if there is a large sandy plateau region, it would be best not to wear. But do not wear contact lens wear and with little altitude plateau.
6. Beginning of the plateau feeling fever, ear, normal right?
because people in the highlands of the blood pressure values ??than in the plain areas will have increased, so the heat is normal bodily sensation, usually in plateau normal body temperature is 0.5 ℃ higher than usual to 1 ℃, but if the heat
also accompanied by other physical discomfort, you should go to the local hospital for examination, the case of a fever caused by the common cold, the patient should be quickly evacuated to a lower altitude where treatment. BTE phenomenon occurs in the plateau region is normal, this is due to lack of oxygen caused by the hearing body.
7. On the plateau can drink?
recommended not to drink in the plateau region, especially in the elderly over 40 years of age, because alcohol will increase the load on people heart and blood vessels, and often will increase the altitude sickness, and even induce cerebral hemorrhage and other cardiovascular the onset of disease.

Wearing contact lenses cause thinning of the cornea do?
Now, a lot of people to the beautiful, small wear contact lenses.
But some say, the longer wear contact lenses, eye corneal abrasion more
obvious, this statement makes some people uneasy to wear contact lenses.
What will not wear contact lenses to make corneal thinning?
ophthalmologist told reporters, wearing contact lenses cause thinning of the cornea is not correct. However, due to wear contact lenses on corneal inflammation caused irreparable harm.
one view, contact lenses make corneal thinning "long-term wear contact lenses will wear eye cornea, the longer, wear more obvious"
According to reports, the normal human corneal thickness of 500 microns or more, the cornea becomes thinner with age, but this is a relatively slow process. The doctor observed that patients with myopia to wear contact lenses, corneal annual reduction of approximately 5-10 microns, the most obvious symptoms of a patient's cornea is only 420 microns.
many reasons causing thinning of the cornea, there are physicians believe that wearing contact lenses cause thinning of the cornea is not correct. Many reasons causing thinning of the cornea, such as high myopia and so can corneal thinning, but said that wearing contact lenses cause thinning of the cornea is theoretically also could not make this conclusion, let alone clinical statistics. While wearing contact lenses does not make corneal thinning, but it will lead to inflammation of the cornea. Optometrists say that some people are often found clinically due to prolonged wear contact lenses, do not pay attention to eye health, over time, the eyes appear red, pain, photophobia and other symptoms, which is commonly known as keratitis.
contact lenses irreparable damage to the cornea contact lens on the cornea damage is irreparable, but the people who wear contact lenses or more. Some big glasses shop every day just received a dozen student customers will, but most of them from eye exams, glasses, optometry shop to try them all at once.
experts believe that contact lenses are a medical supplies, choice and be sure to wear a doctor or a professional optician guidance. In addition, experts say, not everyone can wear contact lenses, people with keratitis, conjunctivitis, diabetes and other chronic diseases as well as people who just can not wear contact lenses.
If you already wear contact lenses, the following precautions must be observed:
a daily wear contact lenses should not more than 10 hours;
two, can not wear contact lenses overnight;
three, contact lenses and glasses all ready one, used interchangeably.
