The cost of LASIK eye surgery

January 13th, 2010 by George Manche No comments »

Some national chains advertised LASIK eye surgery prices as low as $299 per eye, but the financial reports of those same chains showed that the average LASIK cost is about $1,350 per eye in 2002. New technology increases LASIK cost, such as laser flap technology and custom or wave front LASIK. Laser flap technology of a LASIK eye surgery is a procedure, in which the LASIK flap is created with a laser rather than a micro keratome, and the patient may has fewer flap complications and has a greater likelihood of achieving 20/20 acuity or better. So it typically costs more than traditional LASIK eye surgery. Custom or wave front LASIK eye surgery involving using wavefront technology to measure and map the aberrations and vision problems may used when the eye fails to focus light rays correctly, also increases LASIK cost.

After rising for several years, LASIK cost seemed to stabilize from 2006 to 2009. Industry sources report that the average LASIK eye surgery price in late 2006 was about $1,950. In 2007, LASIK eye surgery and laser-based procedures charged at a single price cost an average of $2,099. And at prices reported in 2008, the average of LASIK cost rose only slightly, to $2,105. The average LASIK cost reported in 2009 was $2,140.

Note that the price of LASIK eye surgery may varies from about $1,400 to $3,600 per eye based on many factors, including your individual prescription, where you live, and which surgeon you choose and which technology is used. Many eye surgeons don’t charge a separate fee for new technologies used in LASIK eye surgery, and instead quote their price as a single fee.

Other laser eye surgery average price in 2009 is listed below: CK: $1,500 to $2,900; PRK, Epi-LASIK and LASEK: about the same as LASIK; Refractive Lens Exchange (RLE): $2,500 to $4,500 per eye or more, depending on extra costs such as facility fees.

How to determine kid’s prescription and make prescription eyewear

January 13th, 2010 by Andrew Rabinowitz No comments »

For kids under age of 12 parents and doctors should be cautious to determine the prescription and make prescription eyewear for them. Kids with refractive errors, if deemed to permanent, also need to be corrected by using prescription eyewear.

Same as adult, the kid’s vision errors also include nearsightedness, farsightedness and astigmatism. The rules for making kid’s prescription eyewear are different from that for adults.

For kid’s nearsightedness, doctors usually pick the lowest possible diopter degrees to get the clearest possible vision. For patients with very high diopter degrees, doctors will recommend to reduce the diopter by 1/3. As long as the kid can read and write after wearing the customized prescription eyewear, it is ok. This kind of prescription eyewear with reduced degrees helps benefit the growth of kid’s eyes.

If the kids before school age are physiologically farsighted without too much vision disorder and strabismus, there is no need to wear prescription eyewear. If the hyperopia kid has the symptom of vision fatigue, then a pair of prescription eyewear is necessary. Kids with farsightedness +3.00 or above, prescription eyewear should be worn, but the lenses power should be reduced by 1/3.

For kids with low power of astigmatism, no prescription eyewear needed. For higher degrees of astigmatism, prescription eyewear will also be made in reduced degrees.

The principle of 3D movies and 3D eyewear glasses

January 12th, 2010 by Jay Furlong No comments »

The 3D movies stimulate people’s passion on 3D eyewear glasses. The 3D movie gives people a novel feeling compared with the traditional 2D movies, which makes you feel like you are involved in that action. Obviously, people are curious about the 3D movies and 3D eyewear glasses novelty and the principle of them.

A brief introduction on the principle of 3D eyewear glasses are given in the following. First of all, we should know the working principle about eyes. Our eyes are spaced about 2 inches apart. Therefore, each eye sees the world from a slightly different perspective, about which you may not realize before. The brain is able to correlate the two eyes’ images even though they are slightly different. The binocular vision system mimics this process by presenting each eyewear glasses with a slightly different image.

In fact, the binocular vision system operates in a very easy action. Taking the play of 3D movie for example, two cameras are needed to photograph the same image from slightly different positions to display on the screen, but the two images are different-colored. A special eyewear glasses are needed, too. The eyewear glasses have the red/green or red/blue system, which means one of your eyewear glasses is red and the other is green or blue. The filters on the eyewear glasses allow only one image to enter each eye, and the rest action is left to the brain. A stereoscopic effect is produced by the feeling of distances-difference.

But the red/green or red/blue eyewear glasses can not provide you with a high quality image because you are using the color to give the separation. So the polarized system is more recommended in 3D effect. In the process of this system, two synchronized projectors project two respective views to the screen with two different vertical polarizations. The eyewear glasses allow each image into each eye because the lenses are also different-polarized.

3D movies, together with the 3D eyewear glasses make you feel excited about the world. Understanding the principle of the 3D effect, you must be surprised about how simple the principle of 3D eyewear glasses is and how amazing the stereoscopic effect shows.

Amblyopia treatment

January 11th, 2010 by Andrew Rabinowitz No comments »

Also called “lazy eye”, amblyopia is an eye disease that causes reduced visual acuity in one eye that is uncorrectable with lenses. 1-5% of the population is estimated to be affected by amblyopia.

The problem always starts during early childhood. The reason of amblyopia is the no transmission or poor transmission of the visual image to the brain. In another way, the eye and the brain are not working together properly. The brain favors the other eye without amblyopia. The disease may also occur on children with cataracts, strabismus, droopy eyelids or crosses eyes. Amblyopia may also happen after tobacco or alcohol consumption.

Early detection is essential for amblyopia treatment. The first years of life are critical for eyesight because the vision pathways in the brain must become strong early. The vision system is mature before a child gets 10. According to clinical statistics, children under five get the best results after amblyopia treatment. Adolescents aged 13 to 17 are hardly to completely recover.

Since there are different reasons that cause amblyopia, the treatment must touch the point. Glasses or contact glasses may solve certain problems. If the amblyopia is due to cataracts, droopy eyelids or crossed eyes, surgery is needed. Another simple way of amblyopia treatment is to force the child to use its amblyopic eye most of the time so that it will get stronger by covering a patch over the normal eye. The treatment should go on until the vision is ok. Currently, various clinical trials and experiments are conducted by experts for more effective amblyopia treatment.

Brief history of eyewear

January 10th, 2010 by Mark Burns No comments »

When we think about all the inventions in history, we can never ignore the invention of eyewear. Without eyewear, our life will be much worse off.

The history of eyewear can be traced back to 2000 years ago when ancient Chinese were believed to have invented the first protective eyewear for shielding the eyes from some evil forces. Around 1000AD, the Italians developed the first eyewear called reading stone for the purpose of corrective aid. After reading stone, in late 13th century, it was also Italians who invented the first eyewear with sidebars.

As the main part of the eyewear, lenses went through a very long period of time to reach today’s shape. The early lenses were quartz. Inventors spent hundreds of years to make the lenses of visual aid out of glass after they solved the headaches of bubbles and other obstacles. Modern lenses are made of resin which is cheap and shatter-free.

Another part worth mentioning is the history of temples’ invention. In 17th century, Italians and Spanish tried to use ribbon over the ears to fix the eyewear on the nose. Adding to this idea, Chinese used stone weight to hold the eyewear in front of eyes. Finally in 1730, an British eyewear technician got the idea of today’s temples and successfully solved the problems of eyewear mounting.

Before 20th century, a lot of Europeans thought wearing eyewear is a thing of ugliness. With the advance of eyewear design and technology, nowadays people already think eyewear as a piece of face ornament boosting people’s attractiveness.

What are eyeglasses?

January 9th, 2010 by Paul Benjamin No comments »

In simple words, eyeglasses are a combination of frames and lenses that can be worn in front of people’s eyes for the purpose of correcting vision and protecting eyes from harms of UV rays or some other special threats in different environments.

A pair of typical contemporary eyeglasses consists of two temples, two hinges, two noses, a bridge and two pieces of lenses. Early lenses are made of quartz which was very expensive. It took hundreds of years for scientists to develop the eyeglasses lenses out of glass which made the eyeglasses lenses a lot less costly and affordable to general people. Modern eyeglasses lenses are mainly made of plastic making the lenses of the eyeglasses more breakage-resistant. The two mostly-used plastic materials are CR-39 and polycarbonate. Frames of eyeglasses are basically made of metals and/or plastic. Most of the efforts made in present days are to reduce the weight of eyeglasses and made the eyeglasses-wearing more comfortable and be a piece of art and fashion.

As for the history of eyeglasses, the concrete inventor of eyeglasses was unknown. It was around 1000AD, the first corrective vision aid called reading stone was invented, it was a quartz sphere that was put on top of the target(book) to be read and was used as a magnifier. The first wearable eyeglasses was believed to be invented by an Italian Salvino D’Armate around 1284.

Some historians believe that Chinese invented the eyeglasses 2000 years ago. But it was not for the purpose of magnifying and corrective function, it was for the protection of eyes from some evil forces.

In United States about 60-70% of the adult people are wearing all types of eyeglasses, including sunglasses.

How is the plastic eyewear frames made?

January 7th, 2010 by Sam Sutton No comments »

Eyewear frames industry is becoming very competitive because fashion factors are involved in addition to its function as vision aid. Most of the famed eyewear frames are made with greatest care and precision. We take the example of plastic eyewear frames to explain in detail how the eyewear frames are manufactured and processed.

  1. Eyewear frames manufacturers will first design the frames using own designers or outside consultants.
  2. Based on the design of eyewear frames, factories make the steel die. Put the steel die in the punching machines to punch the blanks of eyewear frames fronts out of the plastic sheets with the appropriate thickness and colors. This blank becomes the fronts of eyewear frames.
  3. Use a router to cut the grooves for holding the lenses.
  4. Put the metal hinges onto the two ends of the eyewear frames fronts. Mostly manufacturers use supersonic to heat the hinges and then insert into the front.
  5. Punch the temples out of the plastic sheets like the fronts. Put the hinges onto the ends of the two temples.
  6. Adjust the angular fit of the whole eyewear frames to make the frame front tilt a little from the wearer’s top to bottom. This is a decisive step in making high quality of eyewear frames.
  7. Heat the fronts of eyewear frames in oven to soften and then shape the fronts based on the curve of the people’s face.
  8. Polish the fronts and temples to make the whole eyewear frames smooth. Any scratches are not acceptable.
