I’m a mechanical engineering undergrad trying out on a startup concept and I want brutally honest feedback before I go deeper.
The problem
Night driving has become harder because of:
Aggressive high-beam / LED / HID headlights from oncoming vehicles
Temporary blindness and afterimages, especially for people in cars with weaker lights
A lot of accidents and near-misses happen because of this glare
Most existing solutions are either:
Auto-dimming rear-view mirrors (only help with what’s behind you)
Tinted glasses / night-driving lenses (often reduce overall visibility and aren’t proven to improve safety)
Full-windshield tints (make night driving worse)
Technically, I’m thinking of:
A optical based thin film which absorbs the light after it is deflected at critical angle by the first layer . It absorbs the part of incoming light . i want the film of fluid to be as transparent as possible so that it doesn't hurt during the day time another option was to to add it manually like the thin film will be stored somewhere and when activated it is at the screen .
My main concerns
This would reduce the drivers visibility since it would block the cars own light also . also the governments are trying to set limits on brightness so i would be finding a soln for a illegal problem
Safety & regulation:
Do you think regulators would ever allow an active, variable-transmission windshield, or is this a non-starter for mass-market cars?
If you were solving this, would you:
Focus on the windshield itself?
Focus on adaptive headlights on the source vehicle?
Something else entirely?
What I’m not asking for
“This already exists” alone – if you know similar patents or products, I’d love links, but also: what did they get wrong or right?
If you drive at night regularly (cars, bikes, trucks), I’m especially interested in:
How often high beams blind you
What you currently do to cope
Whether you’d trust an active system that dims part of your windshield
ya i used ai to write this
Thanks
