okay.. so what is the DNA Wisdom for good eye protection with Brooklands screens, my eyes tend to stream so goggles or close fitting glasses will be needed i think.. also i am thinking a leather flying helmet will offer some protection from the draught and pebbles to the head.

Views?

I use Adidas ClimaCool glasses - can be (sun) glasses, or goggles... and have interchangeable lenses.
Can also use prescription inserts.

As for head ware, I do have a leather flying helmet, but actually use a beanie most of the time (when cold).
In the sun I don't bother, or wear a buff as a cap:

It varies for me depending on weather, I also use mine in all weathers all year,
Red hot in France = speedos and ray bans.
Long bits on motorways to get there = neck buff and Hagloffs beanie and clear cycling type glasses or wrap was round ray bans http://www.blazesunglasses.com/ray-ban-rb8305-tech-dark-carbon-sunglasses.html/?utm_s ource=GoogleShoping&utm_medium=cpc
if it's wet or over a 2 hr drive full face lid.
Dry winter uk blat = neck buff and as above glasses.lid in boot in case of rain( it hurts dude)
I've tried Wiley x glasses/ goggles, found them uncomfortable with strap, let too much light in sides with arms.
Oakley iridium ski goggles, comfy as fook but looked a tool.( same for ski helmet)

Roll cage and Brooklands, for last 3 years, put the screen on for one blat with the mrs to keep her quite but took it off as soon as I got back, hideously drafty with no doors,. Brooklands is the way ,far more comfortable environment with no or half doors.

Adidas Clima cool bought

There is always the famous Seven Speed ultra beanie

Am in same position as Minty in that I do get eyes streaming when in wind flow. was thinking of motorcycle sun glasses as they usually have a soft pad seal and side protection. was thinking of just ray bans, but lost a pair once when I looked over my shoulder during an overtake (was in an MGB) and wind whipped them off my face.
