Reflaction

Dozer & Howie

I have spoken to the Oakley and Rudy Project folks plus my Optomitrist re: distoration of Rx lenses. What the reps at Oakley told me was that for any Rx lenses, they create a half dollar size circle in the middle of the lenses to include any progressive/bi-focal lenses. This leaves the peripheral vison uncorrected, and subject to distoration plus, the blurring that comes when one looks at an object at the boundary of the Rx lense and the uncorrected portion.
The Rudy Project folks told me that they create a Rx for the entire lense using computers and lasers to create the Rx (including the b-focals. They informed me that this process greatly mitigates any distoration for the sides.
This is the first time I have heard the term"reflaction" but, if it close to the definition of refraction, and I understand the effect it creates, I will need to do a little testing on myself to experience the effect first hand to at least beware
of the impact. Rudy Project is checking to see if they can add the "flash" (their term) option, it is a treatment similar to the mirroring the outside of the lense to reduce glare. Thus far, the Rudy Project folks seem to be the most forthcomming and informed regarding technical information on their product, and the impact of progressive Rx lenses. Rudy Project volunteered that they have produced many for the military (mainly Army helicopter pilots) primarily with the red lenses which when I tried them, seemed to provide a sense of greater clarity of detail for up close work (< = 10 ft). I have yet to contact the Sawfly folks so, my research is incomplete. The Rudy Project folks mentioned that Oakley is currently marketing to those folks 25 and youner, with the effect of the glasses being designed for the younger, leaner, smaller faces. I went to the Oakley shop and tried on several pairs and they did not cover my eyes & face quite as well as the Rudy Project (disclaimer, I have no financial interest, connection or emotional bonds with any company mentioned in my post). The Rudy Project folks told me they design their glasses for the more, mature, seasoned, older folks whose head & face is often larger than the tenager/young adults.
My Rx is not that strong. I have been told that will allow for better lense creation. I have no idea if this is a true statement. Once I get the glasses, and have any opportunity to use them, I will pay attention to this "reflaction issue", take them for a test drive and report back.

Best Regards
