Be Careful Of Cheap Glasses

November 16th, 2009 by Richard Schneider No comments »

Buying glasses are originally an expensive exercise. In ancient times, only the nobles could afford to purchase eyeglasses to see things clearly. Although in modern time, glasses have been in mass production, they are usually costly, especially when you want to buy a pair of glasses of high quality.

Fortunately, there have been many websites and stores claiming that cheap prescription specs are available, even some 75% off the normal retail price. It makes the general public excited. However, I want to remind them that when you prepare to purchase a pair of those cheap specs either on internee or in stores, ask yourself: how good are these cheap specs? Are they as qualified as those priced high? As an old saying goes, “you get what you pay for”.

Eyes are so important to us. They might be, given the choice, the most important among the five senses. It is with the eyes are we able to observe this beautiful world and tell right from wrong. Therefore, to purchase a pair of qualified glasses is a must, or our precious eyes may be harmed unconsciously.

Therefore struggling between the two minds of protecting eyes and saving money, how can you get a balance? Do you have to abandon one for the other?

Maybe it would be not so complicated. As long as you find ways to search relative information concerning the retailers, making sure their specs are good, you can have two hares at the same time. Then how to research? Here are some tips:

If you are going to buy cheap glasses on websites, you are necessary to always look at the About Us page to obtain the sellers’ qualifications and operating history. If possible, find the certificate of quality. Usually, the supplier will up load them in their websites. Therefore, if there is not, may be it is an implication that you should take a second thought about the glasses quality they supply. Moreover, make sure there is money back policy, which means if you are not satisfied with the glasses, or something happen to the glasses, you can ask for your money back.

Another simple way is check whether the supplier is credible or not is to type his name or his store’s name into the Goolge to check if there have been any major problems.

If you are going to buy cheap glasses in stores, things come to be simpler. You can use a supplier who someone you know has recommended.

Keep those tips in mind when you choose cheap glasses either on Internet or in local stores. Then you are more probably to choose a pair of glasses of good quality, or at least those worthy your money.

I once have tried to buy a pair of glasses on Internet. By those tips, I finally got one beyond my expectation. I mean with a little amount of money I was able to purchase a pair that maybe prices four times higher in exclusive stores. If you are careful enough, you can have a try as well.

Zinc can slow down the cause and development of age related macular degeneration (AMD). Therefore, taking zinc tablets when you are lack for it.

Another kind of nutrition is also quite important. Anthocyanosides can make capillaries stronger and bring more about rhodopsin. Bilberry jam is of this kind.

Advanced Lasik with Wavefront system

November 14th, 2009 by Edward Turner No comments »

Wavefront system is the most advanced technique available today in Lasik surgery. It is a computer assisted mapping system which is first developed for use on adjusting the optics of the telescopes. Because almost every mirror that is made on earth has abnormalities, which is caused by the gravitiational pull of the earth existing all the time during the process of making mirrors. In order to get a clear picture of the outer space of solar system, the wavefront mapping system is developed to eliminate the effect of all abnormalities of the mirror.

After years of development in the field of astronomy, wavefront mapping system has become a tried technology, and introduced to Lasik surgery. It is now utilized on every type of eye laser surgery today, for instance, Lasik, PRK, LESIK, Epi-Lasik, and IntraLase.

Wavefront mapping system is used in two periods, before and during the Lasik surgery procedure. Before the Lasik surgery, wavefront mapping system is used to exam the eye condition, to judge if the patient is a suitable candidate for Lasik surgery. There is about 6% of the American people is not suitable to undergo a Lasik surgery. Because there maybe a high risk of getting side effect during the surgery due to the bad condition of the patient’s eye, or there is the possibility of not being corrected to 20/20 vision though Lasik surgery. If the patient is a suitable candidate, then the wavefront mapping system can calculate exactly how to reshape the eye for 20/20 vision.

After the initial exam, the wavefront mapping system will be used to guide the laser to reshape the exactly area of the corneal during the Lasik surgery. It makes the process more precise than the traditional ones. Although the wavefront mapping system can give the best possible result, it is important to know that not all patients will achieve 20/20 vision even use this advanced guiding system.

Get an exam for cornea before you wear contact lenses

November 14th, 2009 by Sam Sutton No comments »

Nowadays, through the technology of contact lenses has got an incredible improvement in test and diagnostic capabilities, still, contact lenses can damage contact lens wearers’ eyes in a complicate way.

Besides the basic testing measures such as refraction, cornea readings and corneal health evaluation, proper contact lens fitting and follow ups still need to take the corneal topography and endothelial cell count measurements into consideration. The corneal topography examines include the tests of the outer most layer to make sure whether the cornea irregularities, curves or pathology. The endothelial cell count examine the inner most layer, which is one cell layer. The number of cells per unit area and the quality of the cells are evaluated by the ECC, it said there are 2400 cells per unit area which are similar in color, shape and regimented. Once any change happened in the cell, the cell would die and leave a gap in its original position. The function of the endothelium is pump water out of the cornea. Once it gets some hurt, it will affect the corneal swelling, thickness, glare, and, of course, the ability of vision adjusting will decrease.

People who wear contact lenses should get an ECC to certain the function of the eyes is okay. Once find any abnormal situation, the wearers should make some changes in contact lens wearing.

The size and appearance of the cell in endothelial layer cause polymegathism, which means the ability of the endothelial cell to pump water from the cornea becomes weak. As a result, people get opacificrion, which also called cloudy cornea. Essentially, the changes are caused by the increase of lactate, the PH has changes, which decrease the cellular ATP and increase the endothelial hypoxia.

All of these are caused by contact lenses over wearing. The contact lenses not so fit the eyes brings about the endothelium overload, which makes the number of irregular cells increase. Some cells may be really abnormal.

People who get serious Polumegathism contact lens wear should stop wearing contact lens or reduce the time of wearing contact lens a lot, less than 10 hours per day. There exist highly permeable contact lenses which can allow enough oxygen to cornea.

People should do their best to avoid any corneal surgery which may cause endothelial cells loss. What is more, future cataract surgery may develop the technique to avoid losing of endothelial cells during the surgery.

In general, people who want to wear contact lenses should get an exam to make sure their cornea are totally healthy and do not put their frail eyes at risk.

How to select eyeglasses wisely?

November 13th, 2009 by Reza Hyver No comments »

For eyeglasses wearers, even for those who wear glasses for many years, they may still feel difficult and puzzled to select the suitable glass for them. But as we all know, to choose the right pair of glasses with right frames and lenses is critical not only to our vision, but also can play a important role in our appearance and disposition. So we should pay special attention to this. The following will give some advice on how to select eyeglasses wisely.

First, lenses are the point which counts most. Make sure to choose the lens according to your eye problem and eyes’ requirement. For example, if you like light-weighted, scratch resistant lens, polycarbonate lens is a recommended one. Besides, different colors of lenses should be used under different conditions. When you are in a muted environment, it is better to wear yellow tinted lenses; under strong sunshine, amber color is a better choice, but eye doctors usually do not recommend rose color as it is not soft. Another point for the glass color is we should choose the color suits our skin color, which will add some points to our appearance and disposition. After choosing the right color, we can not neglect the shape of lenses, like square, oval or circle, which mainly depend on our face shapes.

Second, the frame is also an important factor in choosing suitable glasses. Nowadays, there are several types of frames, like full frame, half frame and frameless. And the materials of frames are also different, like metal, wood and so on. If you want to have a wide range to select, you can visit some online eyeglass stores. There you can get some suggestions. For some online shops, you can also try on new glasses you are interested in. This is very simple. It is only need to put your photo into the system they designed, and then try on different kinds of glasses to see which is suitable for you. When choosing frames, please note if you are allergic to some materials, as some people are allergic to metals. Then the second point is to choose the one suit your face and make your disposition impressive.

When wearing glasses, you must be careful to some discomforts, and if you have, visit your eye doctor immediately. Even if we don’t feel any discomforts, you should also visit the eye doctor to do some eye tests at a regular time in order to know our eyes’ status and find some small or potential eye problems.

What we should be aware of Amblyopia

November 13th, 2009 by Angela Garrana No comments »

Amblyopia, also known as the lazy eye, is the disorder of eye system which can not recognize the image. In most conditions, the amblyopia usually happens to one eye.

The cause of the problem is not due to the eye disease, but due to no transmission or poor transmission of images to the brain. So the commonly used word “lazy eye” is not very accurate, it is more accurate to call the “lazy brain”. It is the brain but not the eye that does not react to images. In fact, the brain becomes lazy by the reason of not being stimulated properly in childhood. Therefore, it is important for parents to be careful about the eyes of children, and always take the children to the specialist for a regular eye test.

Amblyopia is not the same with intermittent strabismus. Strabismus is a condition of the misaligned eyes. In this situation, your one eye can see the images correctly, while the strabismic eye just can not see the abnormal thing. If the strabismus does not happen very often, you call it intermittent strabismus; otherwise you call it constant one. The symptom is considered to be normal to children up to 6 months. However, not the same with strabismus, amblyopia is difficult to be found out, even by some pediatricians. Furthermore, amblyopia is more likely to be completely cured when you are young compared with the adult.

When you are under the age of two, it is possible to go back to the 20/20 vision with the help of special drops or a kid eye patch. When your brain’s vision system develops completely, especially when you are older than 17 eyes old, the chance of amblyopia cure is impossible, you can only do aerobics to get the eye a little improved. Moreover, unlike the common myopia, amblyopia can not be corrected by spectacles or contacts, and there is no LASIK surgery up to now, either. Amblyopia is a neurological problem. You can only bear it if you have this problem when you are young, and you miss the crucial period to fix it.

Vision development is very important in the life of people. You must be careful about the eyesight when you are young and do eye treatment regularly. If you find that you have eyesight problems when young, please seize the turning point. There is no way to solve the problem of amblyopia, but we should believe that with the development of technology, the amblyopia surgery will be as easy as the myopia surgery.
