What do those of you that need prescription glasses do when using a TT/Tri helmet? I’ve been doing Eddy-style time trials; the TT bug has bitten, and now I’m going all in. I’m near-sighted, so generally wear prescription glasses while riding. I CAN see well enough that I COULD ride without any glasses, but I do prefer the clarity that they give me. I’m unable to wear contacts, so they’re not an option for me. I just picked up a TT helmet, and my cycling glasses won’t fit under the helmet/visor combo. Do I go with just regular glasses, get something like rec-specs, or just go without?
I don’t wear glasses so this is hypothetical, but if your regular glasses fit under the visor and are comfortable/don’t move around, then that seems like the obvious choice. You’ve got the visor doing the “protection” element (from sun/wind/bugs etc.) so the glasses only need to be doing the vision element.
While not TT or tri, I had the same problem with my Casco sprint helmet. I used regular glasses, but eventually the corners of the frames scratched the visor enough that I could no longer see clearly looking back, which is kind of a big thing in track sprinting. In this particular case, a new visor would have cost more than the helmet I ended up buying, and the old one is still great for utility cycling in the cold seasons.
Some helmets test reasonably well with sunglasses. Example, I know a reliable tester that saw a .001 degradation with glasses vs visor with the new Rudy. YMMV
Zenni and Tifosi recently (last 6 months or so?) started selling cycling specific glasses. You can get prescription, photochromatic glasses for around $230.00. Not sure that the frames would work for you, but these are inexpensive prescription sports glasses.
I just wear my sunglasses under the visors. My rudyproject rydons fit under the visors of the poc procen and tt5 well.
