Fokusskærme

Fokusskærme, also known as focus screens or parallax screens, are a type of optical pediatric training aid used to train vision in young children. The device typically consists of a series of concentric circles or a mirrored reflective surface, creating a distorted and magnified image of objects in the distance.

The primary purpose of the Fokusskærme is to help children, typically between the ages of three and six, recognize and focus on objects at different distances. It does this by providing a larger-than-life image of the object, making it easier for children to perceive and understand the object's size and distance.

By training children to focus on the Fokusskærme's distorted image, they gradually develop the ability to transition between focusing on near and far objects. This training aids in strengthening their eye muscles and correcting common vision problems, such as near-sightedness or far-sightedness.

Fokusskærme have been widely used in optical training centers, clinics, and schools for several decades, often as a complement to more conventional eye exercises or treatments. The device has been praised for its simplicity and effectiveness in early visual training. Research studies have also shown that early visual training with Fokusskærme can lead to improved long-term vision and visual recognition skills.

The effectiveness and long-term impact of Fokusskærme training are still subject to ongoing research and debate. Nevertheless, Fokusskærme remain a popular tool in the field of early childhood vision development and learning.
