Serfas Sike-Out Sunglasses

I was looking for photochromic lenses since I ride a lot in the early morning or late afternoon and was tired of carrying two sets of glasses. I compared the range of tints on these to some prescription Transitions lenses (that were very expensive) and of course the latter are both faster and have a greater range of tints. I would hope that would be the case. However these do the job. At high noon in the Colorado sunshine my light-sensitive eyes don't find these dark enough -- however I should choose other lenses then anyway.Comes with a nice compact case if you want to bring along all the lenses on a ride.The design with the nose pads is great -- they stay up on my nose even when I'm dripping with sweat and bumping over rocks.There are slight visual imperfections in the photochromic lenses -- sort of a wavy horizontal line through the lens. I really have to look for it. This is far less noticeable than the sweat and dirt that gets introduced onto the glasses through the course of a ride anyway.

These have held up well. I like the fact I can get new lenses and the kind of lenses I want. They have ok side coverage, with no frame blockage, which is important to me.Update: Their site has limited replacement parts. They have one or two lenses and nosepiece parts but no photochromic lense or frames . The photochromic work well for cloudy days and I can't get extras. Rather disappointing.As for changing lenses it's difficult at first, especially since you are trying not to push against the vulnerable nosepiece. Don't worry you will bend it. Better at least get a few replacements just in case. Parts are reasonably priced. Parts ordering/performance was excellent and they sent an extra frame for some reason, I don't know why but I appreciate it.For the most part the sunglasses stay on ok but not terribly well. This might be due to the frame not being strong enough to keep its shape and tension. This would be a problem if I was looking down while working on something or other. I like them well enough otherwise.

The variable tint lenses work as advertised, but they aren't as optically clear as my last sunglasses. I like the variable tint since I start my really ling bike rides (70-100 miles) early in the morning when it is barely light. I don't finish those rides until the brightest part of the day. Given that range of lighting, these are the perfect concept, but I wish the lenses were more optically clear. There is a slight distortion that makes reading with them difficult. The variable tint glasses that use a plastic lens sandwiched between perfectly clear glass are a lot more expensive and a lot heavier though, so I guess the trade off is a reasonable one. I'm keeping these.

I really like this pair of sunglasses, which I got to replace an earlier Serfas pair. Compared with cheaper shades, the clarity is excellent, as I would expect from an ND filter for photography. Maybe I'm not as fussy as other reviewers, but I do a fair amount of photography. I like the way this model wraps around the head, so that it fits comfortably under the helmet. Had no problems with the nosepads in 90 degree weather, but only biked a few weeks with the new pair, so far. No real break on the price from this seller. My first pair came from a bike shop, which also sells Serfas at list price.

love them love them love love love them! They fit great, I can wear them all day without getting a headache or hurting my nose, I never bother to swap out the lens but I can see that coming in handy. They even look good on me! I look like an idiot in most sport style glasses, Oakley doesn't make anything that fits my face, which is rather round, I guess, but these are perfect. I bought a pair of about a month ago in a store on a whim - i never buy expensive glasses - and proceeded to lose them in a drunken stupor one night. When I realized it in the morning, I immediately went online and bought them again, that's how much I love them.

I'm a hopeless cheapskate so I refuse to pay Oakley prices for sunglasses...and therefore can't compare these to more expensive brand names. But I can say that these are nicely lightweight and pretty easy to exchange the lenses (though putting them in is trickier than taking them out). The adjustable nose rests make these muy comfortable. Haven't had them long enough to comment on durability. Only complaint would be discomfort on my ears when them more than an hour, but I'm bald so that's a problem with any glasses for me.

First, what a great fit. I have a wide bridge to my nose, and "standard" sunglasses NEVER fit. These did, with a few tweaks of the excellent nosepieces. Second, the additional lenses are a nice plus. Third, they look great (although they are a tad on the large side). Fourth, they're really light, optically pure, and the photochromic works great. Last, I have come to hate the polarized lenses that make it impossible to read LCD displays on vehicles, phones, etc. The non-polarized lenses work very nicely for me. I bought a second pair so I could have photochromic for bicycles/motorcycles and fixed-shade for cars (photochromic won't work in cars, airplanes, or indoors because the windows filter out the UV light which makes the shade change.)

This product is especially valuable for people who wear a helmet when riding on two wheels--a bicycle, motorcycle, or a motorscooter. It is tapered close enough to your skull so the helmet can be put on while you are wearing the sunglasses. Most sunglasses have to be removed prior to putting on the helmet.The cost is very reasonable and the build quality is just as good as those sexier brands costing 2-3 times as much. I also think the rose-tint is just perfect for the frequent overcast days happening in the Pacific northwest.
