Eyeglasses for vision correction are really a critical device for all individuals who have a vision condition. Rx eyewear has remained as the major solution for this group of people for many decades. In a typical case, a patient would get his or her eyes examined briefly by an optician or an eye doctor. After that, the lens prescription can be determined and the remaining task is to select a favorable frame. Every patient involves just these several steps and gets their prescription glasses ordered. Of course, the lenses are prescribed according to an individual patient’s vision condition measured during the exam, and the frame is selected based on personal preference. However, this process is to some extent quite concise and simple and the Rx glasses made are roughly customized. In fact, modern lens technologies and frame fitting techniques have made it possible to get an exact pair of custom glasses.
Getting a real pair of customized eyeglasses for vision correction requires two aspects of consideration: one is certainly the lenses and the other is the frame. The eye conditions of patients differ from each other. And every patient has unique facial features, determined by face size, shape and angles etc. An exactly personalized pair of prescription eyeglasses is very meaningful for every patient who chooses this solution. A true pair of custom glasses firstly needs more precise lens fitting. The current ophthalmic methods only deal with the most common vision problems. There is still a group who can not get their eye conditions corrected and a larger group suffering from stars, halos or other apparitions. The newest technologies are able to measure all details of a patient’s unique vision flaws, including eyeball shape irregularities, abnormal lens density, and aberrations of cornea. Lenses fitted based on these detailed measurements can be really more customized.
The other consideration of exact custom glasses is frame fitting. Some opticians or doctors further pay attention to frame details and try to craft glasses that are perfect for each individual. A typical pair resulted from this concept is perfectly shaped to fit a patient’s face, matched to his or her style, skin tone and personality. This requires prior measurement of the customer’s face and even molding the nose.
