It places great importance on glass technologies. In this context, drivers' eyesight is particularly important. various systems to prevent glare and optimize fields of view It has been improved. However, current techniques face some fundamental problems. 15 Electrochromic glasses can adjust their level of transparency using an electric current. This technology is among the technologies that reduce the harmful effects of the sun or commonly used on car windows to prevent drivers from being dazzled is used. However, this type of glass requires the entire glass to be darkened. It makes it impossible to block bright light in only one area, and the light 20 It is slow to react to sudden changes in intensity. This is especially true when approaching from the opposite direction. This makes them ineffective against oncoming vehicle headlights. Also, all the windows... Turning it off also causes extra energy consumption. Polarized lenses are used to reduce glare by allowing light to pass through at a specific angle. However, this technology, unable to adapt to changes in the intensity and direction of incoming light, 25 By providing even filtering across the entire field of view, it improves visibility in low light conditions. negative effects. Photochromic lenses, on the other hand, darken when exposed to UV rays. It has a technology that makes it transparent again when the rays decrease. However, these glasses... 2 Because it only reacts to UV light, it reduces the brightness created by oncoming headlights at night. It cannot offer a solution to the problem. Fixed filtering systems use polarized or neutral intensity applied to the entire lens. It consists of filters. However, these systems adapt to changes in the intensity of the incoming light. is unable to provide and apply a constant filtering across the entire glass surface, driver 5 This negatively affects the overall quality of vision. Also, the existing lighting and glass... Most of their technologies are designed for continuous operation and are high-energy. This leads to increased battery consumption. This situation puts a strain on the car battery, especially during long journeys. It adds unnecessary load and reduces system efficiency. Current solutions are in the driver's eye. It is insufficient in preventing glare, especially in response to sudden changes in brightness. They struggle to adapt, and this jeopardizes driving safety. This... alongside, a precise and dynamic solution to reduce driver eye strain. It cannot be presented. The patent numbered US8405942B2, found in the literature, describes an electrochromic coating on automotive glass. It explains the control mechanism. However, this solution has a regional filtering feature. 15 It does not offer this and requires all the glass to be tinted. US20150353080A1 The document describes a control mechanism on the vehicle windows that depends on the light intensity. This system has been explained. While it provides sensitivity to light changes, it also offers a fast response time. It is limited in terms of regional control. The application document US20170069727A1 is adaptive. It offers techniques related to lighting and image optimization. However, these 20 The technology described in the document addresses the dynamic regional filtering capability of glass. It does not receive. In conclusion, all these shortcomings in current technologies affect driving safety and This necessitates the development of a new technology that will enhance its comfort. In particular, Regional light filtering, fast response time, energy saving and enhanced driver eye comfort 25 An innovative system is emerging as a major need in the automotive industry.

The aim is to eliminate its disturbing effect on the driver. In this regard, only 5 The aim is to provide localized filtering of the area from which the light is coming. This allows the driver to... The aim is to maximize driving safety while maintaining a general field of vision. The aim of the invention is to intervene in bright light sources as quickly as possible. The goal is to quickly reduce the disturbing light level to which the driver is exposed. This allows for sudden changes. 10.

The aim of the invention is to produce a product (with brightness and) at a level that will not affect driving comfort and safety. The aim is to ensure that no filtering is done for (high intensity) lights. The aim is to enable filtering only when needed. This way, unnecessary filters are eliminated. This prevents both excessive energy consumption and unnecessary filtering. 15 The purpose of the invention is to perform the filtering process according to the light source or the movement of the device. The goal is to ensure it updates periodically. This includes the position and transparency of the filtering layers.
