Among the numerous options of eyeglasses, a customer may have difficulty in selecting a personal-suitable one. Both eyeglass lenses and frames have many types according to styles and materials. It is always necessary to differentiate metal frames from plastic frames, and compare glass lenses with plastic lenses. While eyeglass lenses are closely related with comfort vision, eyeglass frames are more closely associated with one’s appearance. Choosing an appropriate pair of eyeglass frame is essential to enhance the wearer’s natural beauty and express personality. There are some factors to be evaluated associated with a frame. Frame materials have been emphasized for many years. Nowadays, even metal frames made from titanium, stainless steel and memory metal can be lightweight and strong. These advancements have made frame materials less decisive in showing good look. However, there are some other factors that are determinative when customers try to choose individuals eyeglass frames. Simple questions such as who need round eyeglass frames and who need those rectangular ones are actually commonly considered by the public.
Frame shape is really one of the most important factors to be assessed. As a basic rule, the frame shape should contrast with the wearer’s face shape. With this criterion, it is easy to answer the discussed question in the last paragraph. There are generally two groups of individuals who should choose round eyeglass frames. The first group is people with a square face, which means they have a strong jaw line and a broad forehead, plus the width and length are in the same proportions. The other group contains individuals with an oblong face, which has a long straight cheek line and sometimes a longish nose. Both of these two groups have obvious facial lines or angles. According to the rule stated before, it is necessary to offset such obvious lines and angles. In this sense, round eyeglass frames or similar oval frames are the right choice. Based on the same rule, those individuals with oval or round faces should choose rectangular eyeglass frames.
In fact, frame shape is not the only factor associated with personal appearance. There are also decisive elements including frame size and frame color. Considering the first factor, the frame size should be in scale with the wearer’s face size. And the frame color should repeat the user’s natural coloring. Both of these additional factors are as equal important as frame shape. Round eyeglass frames should also be given a proper size and color.

The functions of glasses are not limited to only rectify myopia, but also include the function of pleasing people’s eyes. Therefore, wearing a pair of glasses that suits your facial form will greatly help show your characters and make you out-standing.
Several kinds of spectacle frames can suit oval faces. Oval faces are suitable for almost all kinds of frames. But the size of the frame should be proportionate to the size of the face. Especially for women wearers who have oval faces, they can choose any style of frame, but better not frames with straight lines or frames which are to tall or too oblate.
People with round faces usually have a much shorter face. Considering this, they had better wear slender frames with a little curved shape to harmony the whole feeling. Frames with angles or squares are good for adorn facial streaks and stress the ordinate.
For men, it is better to choose oblate or pear-shaped frames instead of ones which are too round or too square. For women, in principle they should avoid any frames that have too obvious features. Frames that are more oblate are proper. Too round or too straight frames should be avoided either.
People with square faces usually have much broader cheeks and shorter faces, thus looking firm. Frames with a little curved shape can make their faces look softer and ease the too broad cheeks. What’s more, the frames should be broader than their faces. Therefore, the faces can look much more slender.
Due to that their faces are long; the frames for people with long faces should cover as much of the face as possible and thick lines are preferred. For men, frames with higher degrees are preferred such as high frames like square ones. For women, to ease the too long faces, frames should have angles like squares and the les rings can be higher.
Otherwise, glasses are very sensitive with aesthetic defects of facial details. Usually, the top of frames should parallel with the eyebrows and their height should be equal or close. If someone has a too tall and straight nose, frames with lower bottoms or double lines are better suitable for them.

The Neuroptics pupillometer is a state of the art device used to measure the size of the pupil in real life conditions. We acquired this technology in relation to a new FDA study that is beginning soon at Dishler Laser Institute. In learning about this device we are so impressed that we have decided to use it for all of our LASIK evaluations to measure the pupil of the eye prior to surgery. This device uses infrared light to measure the pupil 39 times per second for two seconds and then averages these readings to give an average pupil size which is accurate to 0.1 mm with a digital readout. The human pupil is never stationary and constantly is changing in size depending on lighting conditions. Even when the light level is constant, there are pupil fluctuations known as hippus. We are not so concerned with pupil size in bright light, but in dim light a large pupil can potentially cause issues if not considered prior to LASIK surgery. We measure the pupil in a controlled dimly lit room with the patient focused on a distant object. This is because near vision targets can also make the pupil contract, similar to the effects of bright light, and thus give an artificially small reading of pupil size.
We have learned in LASIK that there is not a direct correlation between pupil size and night vision complaints. There is also not a direct correlation between pupil size and the size of the treatment performed during LASIK or PRK. That being said, there is some relationship between pupil size and the treatment plan which makes accurate measurement of the pupil important. While many laser centers still “guesstimate” the pupil size, and others use the Colvard pupillometer, very few have this advanced technology. What is so interesting is that real vision is related to the size of the pupil averaged over a few seconds, since the pupil is constantly in slight motion. Only the Neuroptics device can accurately measure the real pupil size in such an accurate manner. Another factor that confounds this measurement is called vertex distance. Basically this means that deep set eyes can be artificially measured differently than prominent ones. The Neuroptics device measures the true pupil size. In fact the Neuroptics can measure the pupil in total darkness for the largest size estimation when needed.
While the average patient is not really interested in the details of this particular test, what should be apparent is that the Dishler Institute, is really that, an institute of vision technology. More importantly we bring the latest in technology to our patients as we have for the last 25 years. This is only one test of many using the most advanced technology which gives our team of professionals the information that we need to best evaluate your eyes and vision and help you to make a determination as to whether LASIK or PRK or an ICL or maybe no surgery is the best choice for your eyes. There is no reason not to take us up on our offer for a complimentary consultation and have your pupils measured with the Neuroptics Pupillometer, along with many other noninvasive tests done to evaluate your unique eyes and their properties.
We begin with advanced knowledge and technology to evaluate our patients. The Neuroptics device is one new step in the path down the tunnel of light that we call vision.
Dr. Dishler is the first doctor to perform LASIK in Colorado, the first doctor to offer blade free LASIK in Colorado, and is a consultant, lecturer, and inventor. He is involved with several FDA studies and answers questions related to laser vision correction online.
