Segmented Night-Driving Eyeglasses for Headlight Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tinted eyeglasses do not adequately address the issue of blocking or diffusing the glare from oncoming or trailing vehicle headlights while allowing the driver to see outside and inside the vehicle clearly, posing a safety risk during night driving.
Innovation Solution
Eyeglasses with specially positioned shaded areas on the lenses, allowing a central clear area and left and right shaded areas that enable the driver to turn their head slightly to block or diffuse light from headlights or side mirrors, maintaining visibility of dark areas inside and outside the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If tinted lenses are used to block bright light from headlights, then glare reduction is improved, but visibility of dark areas outside and inside the vehicle deteriorates
Solution Approach 1:
The lens is segmented into multiple zones with different optical properties: a central clear zone for normal viewing and dark areas, and peripheral shaded zones for blocking headlights. This segmentation allows different parts of the lens to serve different functions simultaneously, resolving the contradiction between glare reduction and visibility.
Solution Approach 2:
Different regions of the lens have different optical characteristics - the central region is clear to maintain visibility of dark areas, while peripheral regions are shaded to block headlights. This local differentiation of optical properties allows the single lens to address both requirements without compromise.
2Object-affected harmful factors
If the driver turns their head to use shaded areas to block light, then glare reduction is improved, but the ability to see straight ahead may be affected
Solution Approach 1:
The eyeglasses enable dynamic adaptation to different driving situations. The driver can dynamically adjust their head position and utilize different portions of the lens (clear or shaded) depending on the location of oncoming headlights, maintaining both glare protection and driving control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe night driving by effectively reducing glare from headlights and side mirrors without obstructing the view of the vehicle's interior and exterior, enhancing driver safety and comfort.
Implementation Method 1
lenses that have shading on the left and/or right sides of the lens for each eye... use the left and/or right shaded areas of the lenses to reduce or block the oncoming light
Implementation Method 2
leaving an unshaded or clear vertical section in the middle of each lens... see other dark areas both outside and inside the vehicle through the unshaded central areas

AI summary
Disclosed are methods and apparatus that use specially tinted eyeglasses that may be used to block or diffuse light from the headlights of oncoming traffic or trailing traffic reflected in side mirrors, while also allowing the wearer to see dark areas outside and inside the vehicle. Lenses are provided that have shading on the left and/or right sides of each lens leaving a large unshaded or clear vertical area in the middle of each lens, running from the top of each lens to the bottom. In use, when a driver or passenger wearing the eyeglasses while traveling at night or in the dark encounters bright light from oncoming traffic, or bright light reflected in side mirrors, they may turn their head slightly to the left or to the right in order to use the left and/or right shaded areas of the lenses to reduce or block the light, and are still able to see dark areas outside and inside the vehicle through the unshaded central area.
