In the past an eye examination involved Sniper Vision System Review sitting in an examination chair and looking through a device that would scare most children, then declaring “better” or “worse” until the Optometrist was satisfied. This method is acceptable in most circumstances, but due to the subjective nature of the exam, the prescription can be inaccurate. This type of exam isn’t able to detect other conditions that may exist either.
Advances in the field of eye surgery has brought a new method of examination to the table though, Wavefront. With Wavefront all the “better” and “worse” is taken out, and this technology can diagnose a wider range of conditions. The best part of this is that now this technology can be applied to eyeglasses as well as eye surgery.
In a popular type of wavefront exam a light is reflected off of the back of your eye (the retina) and a map is made from the way that the light travels in your eye. This exam is simple, requires no subjective input, and is almost instantaneous. More accuracy is assured with this method, and more conditions can be corrected from this map.
As pointed out before, this technology can be applied to eyeglass lenses, here’s how. In optical laser surgery, such as Lasik, a wavefront map is used to guide and optimize the laser that creates a custom eye surface (cornea) to achieve the best focus possible. Now manufacturers are using this same precision to correct common issues like nearsightedness, farsightedness, and astigmatism along with the higher-order conditions.
