Children need healthy eyes in order to get the most out of school.
Being active outdoors supports healthy eyes and eye sight because:
- the eye lens works hard to adjust between near and far objects
- the iris works hard to adjust to dark and light conditions
- the eye muscles work hard to control fine eye movements, to give a steady gaze
- the visual cortex works hard to combine information from each eye, and develop binocular vision
- the eyes and brain work hard together to understand perspective and see objects as 3D
- the eyes and brain work hard together to understand shadow, contrast, visual textures, colours, colour tone, colour shades
- the eyes just don’t get the same quantity and quality of information from being indoors, compared with being outdoors.
Some scary recent research as revealed these new facts:
- Shortsightedness amongst children has increased rapidly
- This is due to increased close work on digital devices
- Also a lack of lengthy exposure to natural light, which is 100 – 200 times brighter than indoor lighting
- Severe shortsightedness can affect eye health, increasing the risk of later-life sight loss.
Children need healthy eyes so that they can benefit from all that school has to offer them.
