Best sunglasses for wearing while on the ocean on a sunny day. With these glasses you can see below the surface of the water past the glare. These type pr polarized sunglasses are what 95% of the fishermen wear here in Mexico. I've personally been wearing them for almost two decades and love them. Not cheap but well worth the price IMHO.

.
Amen...I was kinda shocked that Costas did not come up until now!!!! Someone mentioned Oakley and I have no problem with them other than they do not make glass lenses. There are VERY few retail manufacturers that provide glass lenses in sunglasses. Costa del Mar is one of them and I own a pair of glass lenses. Anyway, excellent shades!!!

PS...cannot wear polarized when flying so I do where Oakley non polarized glasses when flying. I am a big Oakley fan....but Costas are better!!!

Wifey B: We wear Costa and Oakley. I just mentioned one of the variations of Oakley. The bad news is I have too many. The good news is not as many as I have shoes.

Optically, I think they are. But that is not why I prefer them. Glass rarely scratches. Plastic will scratch like crazy. The upside to plastic is that they are light....and cheap to make. Costa I think offers cheap(or maybe even free) lens replacement on their plastic lenses. They do not offer the same for glass....I think it is a nominal fee for glass replacement lenses.

Plastic is safer (won't shatter) and is much lighter weight. It has been years since I have chosen to wear glass lenses. Glass only represents about 2% of the prescription lens market in the US at this time iirc.

However, it is much harder to make a distortion free "cheap" plastic lens than it is a "cheap" glass lens. Marketing aside, there is a reason why high quality sunglasses are more expensive, it has to do with the lenses.

Keep in mind that glass polarized lenses are actually a laminate product, two thin layers of glass sandwiching a plastic polarizing filter.

Modern scratch coatings on plastic lenses are actually as hard, or harder, than glass.

Glass is great but at this point the downsides don't outweigh the advantages for myself.

I have a pair of Costa's and loved them until I had to send them in for a repair, yikes!
Now they sit in the case as I'm afraid of damaging them again.
Maui Jim used to be the champion of easy, inexpensive repairs but alas, those days are gone now too.
I've recently (in the past 2 years) switched to Native sunglasses. For whatever reason, these things simply have not suffered damage of any kind in spite of my abuse. They have replaceable, snap in lenses should they ever need them and they are actually pretty inexpensive.
I still love looking through my Costa glasses when they venture out but...

I have found polarized lens work best on the water, grey for off shore and vermillion in shallow water to improve contrast in fining fish. Costas cover my entire eye and socket and don't allow stray light in so my eyes stay relaxed. Unfortunately I wear trifocals so they are not cheap.

I'm using prescription bifocal Bolle, wraparound style to minimise stray light etc. The engine LED display in the pilothouse is difficult to read, but the same LED instrument display on the flybridge is fine for some strange reason. The only other device impacted is my iPad, but I just rotate it 90 and its fine.

Where I don't like the bifocal arrangement is riding the bike - anything near the front wheel is very distorted. On the boat and in the car they are great.

Plastic lens sunglasses are almost always scratched within the first year. My glass sunglasses usually wear out before they scratch....kinda like a diesel outlasting a chassis. In fact, I have never had glass sunglasses scratch. My plastic ones always scratch...always!!!. So the coating might be harder....but they still scratch a LOT easier.

Oakley/Costa del Mar/ Serengetti/Corning

PS....I realize you are the professional...but this is just my experience. I am a sunglass whore and still don't wear corrective lenses(yet) at 51....and not cheaters...yet.

Generally, even with high quality non-prescription sunglasses, they don't have a good scratch coating on the lenses. However, prescription lenses can be made with factory hard coats from Essillor or Hoya that are truly amazing.

The Serengetti lenses from Corning are very nice. I used to wear those all the time.

Maybe a reason for cheaper plastic lenses which may distort is that for many, sunnies are a fashion item they don`t expect will last. Whereas we wear them for protection and better vision, and would pay for better lenses.

[QUOTE="dhays;537523"]Do not wear any tinted lenses at night. Period. It is simply not safe, even if it does make you feel better. It makes the headlights more comfortable, but hurts your ability to see anything else that isn't lit. Just don't do it.

As for sunglasses the rest of the time... Yellow lenses are fine for the gray days as Al mentioned. I did some research on the effect of yellow lenses when I was in grad school and they don't help you see better on the gray days. Whether you test visual acuity or contrast sensitivity, there is no evidence they help. OTOH, pilots invariably prefer them and when I flew I wore an amber photochromic lens simply because I liked it despite the research which said it didn't help. The preference is simply psychological, which is fine by me.

For general wear, your best bet is a neutral gray lens. It won't distort color vision and provides the protection that is helpful. Above all, buy lenses that are 100% UV absorptive in both the A and B UV bands and wear them when in the sun. UV exposure hastens cataract formation and increases the risk of macular degeneration. I always tell my patients to protect their eyes from the sun as they do their skin. So wear sunglasses and a hat.

Sunglasses that provide that UV protection don't have to be expensive. It is cheap to make 100% UV lenses and unless you are buying them at a Podunk gas station somewhere, in the US if they are labeled as 100% UV absorptive they likely are.

It is not cheap to make non-prescription (plano) sunglass lenses that are free of optical distortion. This is where often the inexpensive sunglasses fall down. Take the lenses and look at a grid pattern at reading distance while holding the lenses about 8 inches away from your face. Slowly pass the lenses back and forth over the grid and look for any distortion in the grid lines. Most often you may find it near the edges of the lens. High quality lenses will tend to be uniformly good in this respect. Cheap ones will be hit and miss. So if you can examine a few, you should be able to find a pair that are pretty good.

I don't know much, but this is one area that I actually know what I'm talking about for a change.[/QUOTE

As a skier of some skill, I can attest to the fact that yellow lenses worn on an overcast day are essential. Without them or when wearing gray lenses a skier will absolutely not see bumps or depressions in the terrain making skiing at any speed above very slow treacherous. As for boating I'm not sure whether yellow is of any value on an overcast day.

Costa with glass lenses for me. Unlike Wifey B, I don't have a lot of shoes.

I'm with you. Currently liking Smith Optics with polarchromic glass lenses.

I'd hate to add up how much I've spent in sunglasses in the last 30 some years.

I have had the same experience back when I used to snow ski. The idea is that in conditions with very "flat" light, the amber lens can increase the contrast when viewing the contour of the terrain. This is a little different than the reason shooters and pilots like them because skiers aren't claiming that things are clearer, just that they can see the terrain better.

The best explanation I have seen is that it could be due to the lens blocking the short wavelength (blue) which is so prevalent at altitude and gets reflected and scattered by the snow. This is why "blue blockers" has become an advertising darling. On snow it makes sense however. Reduce the blue light scatter that occurs relatively equally across the terrain then we can pick up the more subtle differences.

Had to give up polarized because of the electronic displays on boat and cars. If you have no choice though just tilt your head sideways and the display polarization will match the glasses. []

Same with airplanes. Also, one of my FOs showed up wearing Costas... I asked if I could look through them. Not only were the displays "wonky", but the laminated heating element in the windscreen was clearly visible with them on....to the point of it being very distracting. No clue how the dude justified wearing those things.
