which way to go.

Stan,

Thank you for the post. The [url=http://www.opticsplanet.com/serengeti-driversgradient-aviator.html]Serengeti Aviator Sunglasses[/url] are so popular. [link=http://www.opticsplanet.com/serengeti-sunglasses.html]Serengeti[/link] Glass Lenses offer the highest [link=http://www.OpticsPlanet.Com]optical[/link] quality and scratch resistance. I wouldn't be able to tell you what to do, but I will be happy to talk about features and benefits. You said you have sensitive eyes so lets speak on light transmission.

[link=http://www.opticsplanet.com/serengeti-sunglasses.html]Serengeti[/link]'s selection of glass lens tints includes:

* Drivers - The brown-colored Drivers Lens is ideal for driving, as it adjusts to the changing light conditions encountered on the road. Drivers lenses provide 24% light transmittance when lightened, and 9% transmittance when fully darkened.
* Drives Gradient - The brown Drivers Gradient Lens is ideal for pilots, or anyone who requires eye protection as well as a crystal clear view. The Drivers Gradient lens provides exceptional clarity and confidence in all conditions. 24% transmittance when lightened; 9% transmittance when darkened.
* Drivers Polarized - the Drivers Polarized Lens is a versatile brown lens that performs under cloudy and harsh light conditions, and features the added protection of the [link=http://www.opticsplanet.com/serengeti-sunglasses.html]Serengeti[/link] polarizing technology. 18% transmittance when lightened; 10% transmittance when darkened.
* 555nm - the green-colored 555NM Lens is ideal for bright light conditions. The 555nm maximizes greens and yellows for greater contrast and clarity. With its silver flash coating, the 555nm gives glare virtually no way in, from any direction. 15% transmittance when lightened; 9% transmittance when darkened.

According to [link=http://www.opticsplanet.com/serengeti-sunglasses.html]Serengeti[/link] every lens gives you the same protection at it's darkest state. If I were you I would stick to the same reliable Drivers (brown) lens that you know and trust.

I hope this helps.

I'm trying to decide which pair of aviators to order. I am replacing a pair of 24-25 year old drivers. The arms have been replaced numerous times. The black is all but gone and it's down to the bare metal. I love my [link=http://www.opticsplanet.com/serengeti-sunglasses.html]Serengeti[/link]'s. So, my pair is non gradient and is a brown lens. I see that I have to pick between the brown, gradient lens [ 6826 or 6783] or a grey lens [7190] that is non gradient. I have pretty sensitive eyes and am worried that a gradient pair will not give my eyes the same protection. On the other hand I'm not sure I'll like the grey lens in the non gradient pair. please tell me what to do. I have to order soon. thx in advance.. Stan
