Oakley water jackets with prescription lenses by Oakley, spendy but its so nice to have vision without the contacts

I has nothing to do with lens color what you described
It could be internal stress patterns in the lens material.....bad polycarbonate lenses are possible
It could be that when you ride and your head is at an angle the horizontal polarization is half way
It could be lenses that have horizontal curved surface but vertical flat surface that messes you up
Some lenses that are wrapped will not have compensated prism built-in to eliminate eyestrain
We see lenses with polarisation off horizontal axis at times
We see lenses with warped surfaced that will distort the polarisation

A nice experienced Optician would be glad to check them out for you at no charge i'm sure

Brown is more high definition than grey....

Can the optician :cool2: explain why is that? :jump:


When light rays go through brown type lenses (true,copper or amber)
.... the rays focus on the retina at a sharper much better angle

Brown type colors reduces a lot of undesirable scattered blue light

You get much better depth perception and contrast !!

It feels less dark to the eyes but the protection is identical...great advantage if sun goes away

Behind a dark grey lens the pupils have to open more and you get less sharp vision as result

:surf: :sun:

Now that you mention it is does occur when my head is at certain angles. I see it mostly to the left and right of my center vision in both lenses. The glasses weren't cheap either so it kinda sucks I paid what I did because I was paying for what I thought were quality glasses. Made specifically for water sports. They are the Julbo Dolphin. I do not like the hologram effect I am mentioning. It feels like something is blocking my vision.

Julbo Dolphin look like very good floating wrap polarized sunglasses
Some people are more sensitive than others to the variation of head position with such lenses
Without having in my hands your exact sunglasses i cannot tell you if anything else is wrong

Do you get the same sensation with other brand polarized lenses?

To protect eyes.... lenses do not have to be polarized if made of polycarbonate or trivex (NXT)
The lenses material blocks naturally 100% harmful rays of the sun

Try non polarized and see if it is better for you
I have found also that the time a day you are out makes a difference
With the sun high overhead instead of lower in the sky polarized lenses can be annoying to some

Remember when sun is at lower angle the light reflected from water (flat surface) becomes....
.....polarized and intensified to a point of veiling glare

Polarized lenses act in such a way as to cancel the amplified polarized light from the sun
Polarization in sun lenses acts like a thousand horizontal mini blinds

One example in when sun is low while driving we drop down the horizontal edge of sun visor
When we are outside and low sun glare veils our vision we put one hand horizontal above eyes

When kiting/kitesurfing polarized feels somewhat unnatural because our heads get tilted so much

For maximum contrast and depth perception try brown tinted instead of grey
With brown you also get less backside reflections from the lenses...easier to see through

I tried out some brown lens polarized and non-polarized today. The polarized brown lens did not have the effect I mentioned in my previous posts. I like the anti-reflective properties of polarized lenses so I will stick with them. Thanks for the info. Very helpful.
