Refraction 101

Georges Laoun Opticien

The tenets of physics are essential to the study of optics. On my journey to become an optician, I must take two physics courses in optics. I am currently in the second course in which we are doing lots of calculations to better understand the possible refractive ametropia of the eye--that is, what happens when light is not properly deviated by the eye to produce a clear image on the retina. In a nutshell: we don't see so well.

Though we're now studying the refractive power of the eye and of lenses, refraction is also responsible, in part, for the distortions of light seen in water. This is of course what I was pondering as I doodled in my notebook...

The truth is, although I am very interested by physical phenomena, physics has never been my strong suit and today, I am troubled by a horrific thought: It is very possible that these physics courses I am taking are already obsolete and that I will have to do them all over again.

Why? It appears that a recent experiment at CERN in Geneva has demonstrated the possibility that there are particles that travel faster than the speed of light. Should this prove to be true, we would have to reinvent all that we have learned in physics the last 100 years! Oh boy...

What could this mean for the optical industry? Thankfully, I don't think the optical world will be turned on its head just yet. To be continued...
