It was around 0C this evening on my way to work and my eyes do not like the cold wind! They tear up with sunglasses on on the short descent I have as soon as I leave my place. I cannot have this happen as I need to arrive at work without mascara running down my face. What type of glasses can I purchase that are excellent at blocking the wind and that I can also wear when it is dark out that will get me through the mild winter days?

Ski goggles over glasses if you need prescription, otherwise just the goggles.

You need full-wrap sunglasses to deflect the wind around your eyes, rather than regular glasses which create eddy points at the edges of the lenses -- often wearing the wrong glasses can make your eyes colder than if you wear nothing at all!

Personally, I hate goggles and only wear them in heavy snowfall or when it is colder than -25C. Full wrap glasses are more versatile, and if you have to stop, say at a red light, you can just puch them down your nose so they don't fog up (harder to do that with goggles).

And for winter riding, nothing beats a set of photochromic lenses that adjust their tint automatically to the light conditions.

I just got large glasses at the eye doctor. Lucky they're back in style.

Go to a safety wear shop and grab a pair of yellow safety glasses in a wrap round style. The yellow is great for flat light like overcast days and at night as they improve contrast. Being safety glasses they will be UV rated. They also have the bonus that even a top end pair might cost you $10.
You can get yellow lenses for ski goggles too, but I think you'd maybe sweat too much in them if your ride is energetic and it's not too cold, and you'd end up with runny mascara anyway.

I use cheap shop/safety glasses from The Home Depot. not these exactly but close. I like the ones that come in a 5-pack. but this will give you an idea. also - why not put your makeup on after you get to work?

Wiley-X makes some sunglasses that have a (removable) ventilated foam seal and head strap that turns them into low-profile goggles. They're in the "Climate Control" category.

I have a pair of prescription Brick sunglasses I really like. In sunglasses mode they do a pretty good job keeping the wind out of my eyes. In goggles mode they still mostly pass for sunglasses, and are very effective at keeping the wind out. The vents in the foam seal do a pretty good job keeping them clear as well.

I found out safety glasses seem to work very well, and my optometrist has them at very low prices, included the lenses. I got polycarbonate lenses and frames for less than $100. I just switch when I get to work.

Excellent idea that comes under the duh why didn't I think of it category. I have a pair of Bolle sunglasses not cycle specific but came at a hefty discount and have great coverage over my eyes, but are useless in the dark. I was getting ready to get a pair of sunglasses with inter changeable lenses, but your suggestion is one I will try.

Yeah, this scenario is specifically what ski goggles are designed to handle.

You can also buy balaclava's specifically designed to avoid fogging up your glasses / goggles to keep your head warm:

Some of those cheap safety glasses do a great job at keeping wind out of the eyes, but they are very scratch prone.

Well, I've tried large safety glasses, and yellow cycling glasses. Neither work well at keeping the wind out of my eyes. I have also just purchased ski goggles for the really cold winter days. I'm sure they will do the trick, but I'd still like to find something for the milder winter days.

I saw another cyclist with completely clear goggles, much smaller than ski goggles. They would do the trick I think, I just need to find them.

Visorgogs might do the trick, if you can get past their odd styling. Don't know if they're available in Canada. But they work for me.
