UK Civil Aviation Authority self-inspection blue laser pointer
The U.K. Civil Aviation Authority have produced an “Aviation Laser Exposure Self-Assessment”, to be used by persons exposed to blue laser pointer light. The ALESA card is available in hard copy, and can also be downloaded from CAA’s website. If downloaded, the Amsler Grid on the first page should be printed so it is 10 x 10 cm, or 4 x 4 in.

From a review of a laser pointer
When staring at the dot in the center of the grid, if the lines appear distorted or there are blank or faded areas, there may be a problem. The person is encouraged to remove themselves from aviation-related duties such as flying or air traffic control, and to see an eye specialist.
The second page has a flowchart of exposure conditions leading either to a “1” meaning unlikely eye damage or a “2” meaning eye damage possibility. If the person scores a “2”, the flowchart suggests they see an eye specialist.
Commentary from Htpow.com: In our opinion, the flowchart could lead to many unneeded worries. For example, there is a question about whether “you continue to see a bright glow even after the laser beam exposure ended.” If Yes, it is suggested to have an eye exam. But by this standard, anyone having a bright spot after being photographed using a camera flash should have an eye exam. In our view, if you get a “2” on the flowchart, do not worry unless you also have any new symptoms or indications of a change in your vision. If you pass the Amsler Grid and otherwise have no visual changes or problems, the laser pointer 5000mw exposure has not changed your vision. This is echoed by the U.S. Air Force guidance in the next section.
