In 1924, the ‘reduced’ eye was created by Gullstrand. A schematic diagram simplified the various components of the eye to six surfaces and using a very small sample (reportedly a handful of dead eyes!) averages were applied. These averages have been used in visual optics ever since, in one way or another, to design spectacle lenses.
Until, in 2014, Rodenstock UK launched the DNEye scanner – a machine that can take biometric measurements of every individual eye it measures.
What does this mean? In an eye examination an Optometrist checks the health of your eye, tests your vision and finds the power that you need to correctly focus light on the back of your eye, the retina. However, light must travel through several surfaces before it reaches your retina and will be deviated by imperfections creating aberrations in your vision. Rodenstock’s new scanner looks at the purity of these surfaces, measures them and can calculate the corrections needed and incorporate these into your spectacle lenses.
How many of us struggle with night driving? It’s a comment we hear from several patients every single day. Although this can be due to all sorts of problems, as a rule, the larger the pupil, the stronger the influence of high order aberrations on the quality of vision. The DNEye Scanner can measure the difference in size of your pupil in different light levels and use this data to create a lens designed to get your vision closer to perfect.
The EXACT measurements taken by the DNEye scanner can then be applied to any type of lens produced by Rodenstock, including single vision, occupational and varifocal.
We have now taken delivery of our DNEye Scanner and include it’s use in our comprehensive eye examination.
