Abstract : It is possible to design protective eyeware for the entire visible region which will not disrupt the user's vision for tasks such as flying an aircraft. This report documents experimental results in eyeware design for the visible LASER spectrum. This research included phase aberrators from various materials such as cellophane tape and wet tissue paper to more exotic combinations such as ethanol and water between glass plates. Preliminary experiments indicate that placing an optical aberrator in the light path before the transform lens can greatly reduce laser beam intensity at the Fourier transform plane. Phase aberrators can be designed for reduced vision impairment where visual acuity is essential. This increases the possibility of designing eyeware to protect against serious damage due to laser beam focusing on the retina. This protection would be across the entire spectrum,not just the small portion as is the case with existing protective eyeware.
