Hello alexer03 and All, Yep ......... the glasses are purpose made.
We looked a many different molds but ended up going for function.
The specs are ours ..... UVA and UVB, shatterproof, temple pieces can be drilled for retainer, tint to our specs.
We bought a fairly large run and so we keep using the same glasses.
As Apple demonstrated, style counts, and admittedly we missed the boat there.
Next time we will get more stylish glasses.
We attempted to gild the lily by having them 'no fog' coated and that caused us some extra work when attaching the prism.
The no fog coating defeated cementing the prism attachment part and we had to manually remove the coating at the attachment contact points which made extra work.
The future may have something like Google Glass or other another video solution, but until then .......
Our Cyclops glasses, while looking like work glasses, are very functional and do not require a battery.
If by using the glasses and keeping your head down more (while seeing the field of view ahead of you and relaxing your neck) would allow you could ride 1 mph faster ...... would that influence your decision to buy?
On a 1 hour ride you would be about 1 mile ahead of your competition.
Which is your dominant eye? And do you have 20/20 vision or corrected vision using contacts?
Cheers, Neal
