Description

1. Introduction

[0001] This document describes an innovative, energy-efficient spectacle system for significantly improving night vision under difficult lighting conditions. The invention has been filed with the German Patent and Trade Mark Office (DPMA) and is currently under examination. The aim is to provide an adaptive optical system that triggers automatic image amplification while simultaneously enabling clear, high-contrast night vision. 2. Technical problem

[0002] People who are walking or passing through poorly lit environments often struggle with visual perception problems. Glare from headlights and changing light sources—streetlights, dazzling lights—makes perception difficult. Conventional glasses or simple blue light filters are insufficient because they do not offer adaptive adjustment and often even lead to worse vision or additional glare. 3. Technical solution / innovative core

[0003] The 'Night Vision' glasses combine passive and adaptive optical technologies into a completely new concept: a) Special filter against blue light; A special yellowish filter reduces the proportion of blue and violet wavelengths. This results in: - significant increase in contrast _ - reduced glare; - clearer contour recognition b) Adaptive electrochromic layer. A transparent film layer reacts automatically to ambient light. - In bright light, the layer darkens - it remains almost completely clear in darkness. - the adjustment happens automatically and without delay c) Optimized brightness sensor An integrated sensor detects the lighting conditions and, if necessary, controls a gentle contrast adjustment. 4. Differentiation from the state of the art

[0004] Existing night vision systems predominantly use stronger image amplification and are expensive. The presented invention differs in that: - Combination of passive vision enhancement and adaptive electrochromic control - significantly more glare protection without distortion - Increased everyday usability for all users (drivers, delivery drivers, anglers, hikers) 5. Energy supply

[0005] The system can be operated via: - an integrated solar module in the upper frame area or - a small battery (0.5-1 Ah), rechargeable via USB-C

[0006] Energy consumption is minimal, and the operating time is several days. 6. Design and ergonomics - Lightweight, shatterproof polycarbonate frame - Dual lens design (protective lenses + filter, internal with adaptive filter) - Optimized clip-on mechanism for users with diopters - High wearing comfort for long-term use 7. Advantages for users - Significantly improved night vision without electronic image enhancement - Reduction of glare from oncoming traffic or disturbing light sources - Natural perception with low eye fatigue - Increased safety for drivers, delivery drivers, hikers and night sports enthusiasts 8. Economic benefits and potential applications

[0007] The concept is applicable in many market segments (outdoor, mobility, security).

[0008] The combination of very low energy consumption, simple production, innovative filter technology and a broad customer base makes the system attractive for series development.

[0009] Following confirmation by the DPMA, a technical cooperation with industrial partners will be pursued.
