Hello RowToTri and All, Actually quite a good idea ..... head down ...... and you can see where you are going .... much safer.
Better awareness and your neck doesn't get as tired. More relaxed position.
Faster. It is easy to just lift your head a bit and look over the prism to see the real world view .... although the very clear view of a large area the and ability to see small pebbles is surprising.
Used in Ironman races for several years .... then the mirror rule was added ..... it would seem to make it illegal in Ironman branded races as one face of prism is silvered.
Too bad .... as it is much safer to have cyclists clearly seeing what is in front of them when their head is down .... for better situational awareness.
https://forum.slowtwitch.com/...ost=6454651#p6454651 Also there is a newer and better way to accomplish all this .... but it still utilizes a prism.
The clip below is from the View-Speed website (which is very slowly being updated).
To buy View-Speed Cyclops Glasses you need to select which is your
dominant eye and you need to have normal vision without glasses (contacts are OK) – as corrective glasses will not fit behind the View-Speed Cyclops glasses.
http://en.wikipedia.org/wiki/Ocular_dominance The Miles test. The observer extends both arms, brings both hands together to create a small opening, then with both eyes open views a distant object through the opening. The observer then alternates closing the eyes or slowly draws opening back to the head to determine which eye is viewing the object (i.e.
the dominant eye).
Please select View-Speed Cyclops Glasses to match your
dominant eye ..... if you are right eye dominant .... select right eye dominant glasses .... left eye dominant ... select left eye dominant glasses ....... the prism will be mounted on the side of the dominant eye for best results.
View-Speed Cyclops Glasses are an aid for keeping the top of the cyclist's head down more even with the plane of the back of the cyclist ..... while providing the ability to see forward for
safety - to improve
comfort and relax the neck muscles with the head in a more normal position which mitigates the effects of Shermer's Neck Syndrome - and to increase
speed about
+1 mph Faster at same power depending on cyclist's previous position.
Cheers, Neal
