“I had been waiting a long time for the Headplay HD, and when it arrived I was really disappointed at first, because I could not clearly focus the picture. The focal distance was just too small. In Internet forums, I have found many who had the same problem. Especially over 35 years or eyeglass wearers.

Younger people are able to focus the image, but it strains the eyes very much and many feel overstrained after just few minutes. Due to the small focal distance, the eyes need to squint more than usual, leading to premature fatigue or to double pictures if the eyes relax.

Many people also complain about the too large field of view of 72 degrees. This feels like sitting in the first row in the cinema hall. The eyes have to travel long distances to scan the image. It is impossible to grasp the whole picture at a glance. However, that is exactly what the pros of the FPV Sports try to do. They look constantly at the image center and try to grasp the whole situation without time-consuming eye movements. Due to the large field of view not a few get dizzy during FPV flight or they must pause early or consider the Headplay HD unsuitable in general.

Furthermore, some complain about disturbing light reflections on the Fresnel lens. These arise from the glowing screen, the illuminated face or by penetrating sunlight. The Fresnel lens has no anti-reflective coating at all, a disturbing groove structure, a very bad sharpness, a milky transparency, it generates color fringing and is difficult to clean in the grooves.”
