cycling glasses over spectacles

[byegad]

My experience of the one pair of prescription insert cycling glasses that I bought, was that while they worked fine on the move they steam up rapidly at the halt or on slow hills when the wind is behind you, leaving you in effectively still air. Taking them off allows you to see, but only at the level of your natural, uncorrected vision.

I did buy some cheapish ones off amazon that you put a prescription insert in. The total cost was about 50 quid. I reviwed them for @Andrew_Culture s veloballs sight heres a link to the review if that permitted. (mods please remove if not)

I use them all the time and find it easy to switch between outer lenses

I went for these on the strength of your review & find them very good indeed. Yes, they can fog up when stationary, but they soon clear when you get going again.

My glasses have fairly small rectangular lens

That is the problem. You need a larger lens and esp a lens that reaches higher up so wind cannot form a vortex over the top edge and also to give you better vision from a low riding position.

Thanks for all your replies. Lots of options, but the best seem to cost a few quid. You do get what you pay for when it comes to glasses. I’ll have to give this some thought.
