Prescription eyeglasses for touring
I'm thinking along the lines of a mountaineering type
frame with prescription lenses that automatically turn dark in sunlight. Frames would have some kind of leather covering AROUND frames and lens to "cup" the eye from all sides and block light coming in thru sides Anyone wearing such glasses or have even better idea? |

I don't think they're particularly applicable for bicyclists (unless you enjoy the smell of sweat soaked leather). yes....glacier glasses that is what they are called but couldn't remember |

The signal that causes your pituitary gland to prompt your skin to make melanin comes from your eyes. If you block out most of the sunlight that would otherwise go into your eyes, you'll tan less and sunburn more easily. Chalo |

Glacier glasses have side shields for a number of reasons, most of which don't apply to cycling. Curved lens glasses are just as effective, but corrective lenses, particularly in high diopters, can be a problem. I've not tried photogray lenses, I don't see the need for outdoor activities. I have found that long days of windy riding can dry out my eyes, but that's relatively rare and not too bad of a problem. I have wraparound glasses (corrected), but mostly prefer plain sunglasses. I did try using small lensed sunglasses for a kind of "poor man's bifocal" -- just look under lenses for maps, computer, etc., but found that light reflecting off my cheeks caused enough reflection off the inside of the lens to be a problem. I suppose I could blacken that area as some sports players do. The problem for me with both wraparound and glasses with side shields is that they restrict peripheral vision -- something I'm very fond of while cycling. They might be worth it in high glare or very windy conditions (e.g. glaciers), but not on my typical rides. One interesting option is the frame that has tiny strong magnets embedded in the bridge and dark lenses that are made to accompany them. My wife has a pair that she loves. Similar to "clip-ons" but without the dork factor. http://www.zennioptical.com/home.php?cat=8 |

Sunglasses would leave my eye sockets pale while the rest of the face and body tanned darkly. These are good quality glass lens Ray-Ban aviators that I've worn for 30 years. I would say pale skin syndrome comes more from genetic predisposition and obsessive application of sunscreen than from shading the eyes with sunglasses. |

I wear an oakley semi-wrap frame (can't go full wrap w/ my script) with drivewear lenses. I absolutely love them - the lenses are amazing. |

I very near sighted and its best for me to keep lens dimensions as small as possible otherwise I get very thick heavy glasses plus vision distortions in peripheral vision So.... was thinking some kind of "John Lennon" style glasses with darkening material around rest of filed of vision |
