Method and apparatus to mitigate small scale laser interference from laser pointers.

Laser pointers can be easily obtained because of their cheap price and availability. Unfortunately, they have become increasingly problematic for pilots and users, resulting in the user's arrest [1]. Hand held laser lights directed at aircraft can temporarily blind pilots and cause eye damage [2]. The disclosed method and apparatus can reduce or eliminate laser light eye damage to pilots during critical flight times (i.e. runway approach). The disclosed method and apparatus can mitigate this light interference by coupling predictive parameters. These parameters work together to indicate the most likely time or environment where laser light interference may occur with smart eyewear designed to block the most common laser light wavelengths.

Existing technology can be combined to implement this method. Developing and existing protective eyewear filter laser light in specific wavelengths via a "static" filter solution. Consequently, creating eyewear that can block specific wavelengths is feasible. It is also possible to use electrochromic glass to mitigate the intensity of a light source (i.e. building glass windows). Finally, GPS (Global Positioning System) can be used for tracking and location identification.

This invention comprises the use of electrochromic eyewear, wherein the electrochromic lens material is selected to filter out specific wavelengths associated with laser pointers (i.e., red = 650 nm, green = 532 nm, and blue = 473 nm). The eyewear is synched to a GPS such that the lenses remain 'transparent' at non-critical times during flight but automatically toggle to filter out the most common laser pointer wavelengths during take-off and landing based on input from the GPS device.

The disclosed smart eyewear application using electrochromic materials, can be controlled manually or automatically via GPS input and synched such that predetermined locations can be entered into the eyewear device. As the device gets within an area of an airport or a critical altitude is reached, the eyewear is triggered to automatically start blocking the wavelengths of choice. In this case, no input from the pilot is required.

There are currently electrochromic materials (ideally a thin film with excellent optical quality suitable for glasses) that respond to specific wavelength frequencies in the visible light spectrum. This disclosure makes use...
