Bifocal sunglasses are amazingly hard to find, so I thought I'd give a pirep on one that works well for me.

It's a brand you would not expect. DeWalt, the tool company. And a price you would not expect either - just $12. They seem to be intended for use as protective eyewear, when using machines outdoors. But I have been flying with them, and they are really good.

The 2 diopter reading lens at the bottom is the right size for viewing stuff on your lap and at the bottom of the panel. If you need the entire panel to be in the reader lens, however, these won't work for you because the reader lens is too small for that.

The optical quality seems to be good. The color is smoke, i.e., gray.

I tried stick-ons, too. I put them on some Ray Bans. And I tested them against the DeWalt on the same flight. Specifically, I tried the Hydrotac OPTX 20/20 Stick-On Bifocals, 2.00, which had good reviews on Amazon.

The advantages are that the stick-on lenses is that:
* they are big, so you can view the whole panel through the reader
* you can put them on any sunglasses you like.

The disadvantage is that the optical quality just isn't as good as a reader lens that was made as part of the lens. At least that was my experience.

The optical quality of the reader lens is better in the $12 Dewalt than in the stick-on lens on my Ray Ban.

I've used them for 20 years. :dunno:

I would not want to trust my eyes to $12 sunglasses. :no:
 
I have sent two pair to Ray Ban to make them progressives. Lens Crafters will do them, but I wanted authentic lenses.
 
This seems like a solution looking for a problem.

Take an eye Doc's prescription to any eyeglass place and they'll happily make you whatever you want.

Just had the annual eye exam today. Told the Doc I wasn't switching glasses pairs like I thought I would and was going for progressives this year.

He suggested we go with the new high quality lens cutting process that results in a larger mid-range area in the "hourglass" at the center.

Also got the usual Transitions in the extra active variety and apparently they've made those even better since last year also.

Never had any signs of any significant higher order issues in the optics, so no need to go do a wavefront/free form lenses but man those sound fascinating once they eventually come down in price. Very cool tech. Machine measures every bump and curve of your eyeball and spits out a prescription, similar to the mapping tech used for laser corrective surgeries but applied to making standard eyeglass lenses. No more "which looks better, one... or two?"

By the way, Luxottica bought out Ray Ban and Oakley. (And damn near everyone else.) Neither is the same company you once knew.

http://en.m.wikipedia.org/wiki/Luxottica

We always buy one pair from the eye doc since he's a family friend, but he's totally stuck in the Luxottica mess. Whatever the frames were that I picked out this year actually say, "made in Italy" on them.

Sometimes if I need another pair for something special I'll order through him, or I'll put the Costco membership to good use, depending on how flush with cash I feel that minute. I like supporting the Doc and his family but he's usually about twice the price. All I can hope is that most of that goes in his pocket.

He also has an impressive retinal scanner. Most insurance won't pay for it, so he has to tack on $37 if you want it and he recommends it for first timers to his office or anytime he sees something odd, or you can just do it every time, as I do. He was able to show me today's shots side by side with the shots when he first got the machine four years ago on the monitor in his exam room. Could also tell the technology has gotten better since then, with better resolution and sharpness. Perfect view of every blood vessel and all of the inner workings of the eyeball. Thing uses a multifaceted mirror spinning at 30,000 RPM (sounds like a turbine winding up when they turn it on) to scan most of the inside of the eyeball in .25 seconds. Wicked cool tech.

I have an interesting feature in both eyes. There's a "sheen" around my optic nerve. This is something usually only seen in young eyeballs. Teenagers. He says it's remarkable I have them in both eyes over 40.

I just joke with him, "Eyeballs are great, Doc. It's the rest of me that is falling apart!"

He also does something many many former eye Doc's have never done for me and I love it. Every exam room has a drawer with a full set of lenses and an old style multi lens frame so when he is sure he's got it right, he'll take a minute to assemble a "pair of glasses" in your prescription and put them on your face. You can tell for sure that he got it right before you leave the office.

Nothing better than a good eye Doc.
 
Just purchased a set of stick ons for my ray bans,seem to work great.
 
For flying, my medical (when I had one) required corrective lenses.

I had radial keratotomy in the 1980's, pre-lasik, and though I have no regrets, I need some minor correction now.

I have progressive bifocals with flip-up sunglasses that stay in the plane. Perfect solution for me.

The rest of the time, I use bifocal sunglasses purchased via Amazon. One set is the $12 Dewalt brand that have already ready been mentioned, and they work fine. At 65, I'm up to 3.25 diopter so or thereabouts for the bifocal portion. Also bought a couple pair of a slightly less expensive brand and they've proven durable as well.

I've had a couple of sets of bifocal sun glasses made by the same place as my regular glasses (Sam's club optical). After 18-24 months the coating starts coming off the lenses. I was told "Don't leave them in the car." Apparently the heat here in central Florida kills them. So now I just use some nicer clip ons over my regular glasses. No regrets so far... (4+years)

Any decent optician can make you bifocal sunglasses as easy as they can make clear ones.

My wife after her lasik has piles of bifocal readers (clear on top, reading glass on bottom) both clear and tinted from readingglasses.com
 
I get my bifocal sunglasses in the local CVS. They have an entire rack devoted to them. A good selection of prescriptions, styles and colors. The caveat is that they are NOT in the same area where all the rest of the reading glasses are, so you have to hunt for them. I they are between $12.00 and $22.00.
I also have a set made by my optometrist. The CVS glasses work better.
 
I hate cheap sunglasses. Instant headaches for me. I used Maui Jim readers for many years before needing a distance scrip on top so now I use Maui Jim progressives. I've tried Costa, Oakley, and Wileyx but nothing compares to my MJs. I wish MJ made clear lenses. I'd buy my regular glasses from them, too, if they did.

I tried those stick-ons on the drop-down sun visor of my flight helmet. Hated them. Re-adjusted the helmet to sit a little further forward on my noggin so I could wear glasses under the visor. Mo' Bettah.

I tried bifocal sunglasses and they just didn't work out for me. Too often it was too dark to read what I had to read with sunnys so I had to have regular readers anyway. If I need sunnys and readers at the same time, I end up with 2 pairs of glasses staged on my nose.

I've been wearing MJ rose for a long time now, best sunnys I've ever found. I totally agree on cheap sunglasses, can't stand green tint either, puts me in a foul mood the minute I put them on. Grey just makes the world seem dull.
 
I have for just a little over 17,000 hours. I guess you must be "Spatial" or something.

Me too... except I don't have that many hours. :D

Cheap sunglass lenses work just as well as high dollar ones as long as you can find them in the form factor that suits you. As far as 'trusting' one's eyes to a pair of cheap sunglasses, let's remember that these are safety glasses so they meet all the OSHA standards.

I tried all the alternatives and finally sucked it up and got a pair of Progressive lenses in a nice pair of RayBans... I also have a photo sensitive pair of progressives that work quite well in normal conditions and I only put on the Raybans when there is a lot of glare or haze...
 
Thanks, Stewart, those Maui Jim bifocal readers do look promising. It's good that they're off-the-shelf with no presecription. But it appears they are all polarized. That might cause a problem with viewing LCD displays like my PFD and MFD.

PolarizedPlus®2: In every pair of Maui Jims you'll find our patented, color-infused lens technology that wipes out 99.9% of glare
 
I wear mine regularly in the plane and out. Never any problem for me. For what that's worth!
 
I did make a mistake with the first set of lenses I ordered from Ray Ban... I got the polarized lenses.

I have used Maui Jims with every Garmin display with no problem except an old monochrome LCD that I had to tilt my head 30° to read. G-500, 650, 750, MX-20, GMX-200, 430, 530, no worries. Use them with my iPad all the time. Still I don't like them with the bifocals though.
 
One of my everyday pairs of prescription glasses have gray Transitions self-tinting and those are polarized, too. Also no problem. They have Transitions lenses that work in the car now, too. Eyeglass technology is improving every time I get new glasses.

I never had a problem with the screens in the corporate airplanes I flew, but the Bus is not doable with polarized.

My problem hasn't been with cockpit panel-mounted displays but with the new iPads. In the portrait position they would go black with most polarized sunglasses.

So now I just have non-polarized and I don't worry about it.
 
iPad in hand, MJs on nose. No vision issue in any iPad position. Older screens had issues but the later ones do not.
 
Polarization is overrated. All you need are good contrast lenses. Violet Iridium is my go to lens
 
I had PRK on my eyes twenty years ago when I was 38. Really great procedure for my quality of life! I have gotten used to readers lately. Distant vision is still good but I really like some magnification for the far distance.

The glareshield on my plane is pretty high, even with the seat cranked up.

So, I had my local optician make a bifocal transition sunglasses with a middle distance computer screen scrip on the bottom and distance on the top half. Bringing the lower/upper boundary to the middle of the lens, It is constructed to come together on a sightline with the glareshield when my head is level.

I'm using Randolph 52mm mil frames with bayonet earpieces.
Works wonderful!
