August is #VisionandLearningMonth! 1 in 4 school-aged children have a vision problem, and this includes problems that can happen even if they can “see 20/20!” A comprehensive eye exam should be a priority to make sure your students are prepared to do well in school!
Here’s a great video by WOW Vision Therapy that shows how kids can suffer from a vision condition affecting their ability to read and learn, even if they have 20/20 eyesight and “no need for glasses.”
Have you heard of Enchroma glasses? Based on the viral video, it looks like they can “fix” colour blindness! Although they can’t actually do this, here’s how they work.
Colour blindness does not mean someone sees the world in black/white or grayscale. People with colour deficiency do see colours, but because of a change in their photoreceptors of the retina, certain wavelengths look very similar. There are different kinds of colour deficiency, but for example, a person might find it hard to distinguish between reds, browns, and greens. The glasses help by filtering out the wavelengths with the most overlap, which cause the most confusion (see pic below). As a result, this allows people to see a bigger distinction between colours, and everything looks more vibrant. They can see shades they’ve never seen before, which were previously muddled together in the zone of overlap. It’s hard to imagine what it must feel like to put these on, but it brings on some very interesting questions about colour and how we perceive colour! 🤩
Here’s a much more in-depth explanation: What is color? Enchroma glasses, neuroscience, and the mystery of color
This 10-month old baby is so happy after putting on her first pair of glasses! She can’t stop smiling when she sees her parents clearly for the first time 🙂
Babies can’t tell you if there’s something wrong with their vision. That’s why you should have your children’s eyes checked starting at 6 months of age. An optometrist can use handheld instruments to determine how the light focuses in their eyes, so young patients and patients with special needs can be examined without having to read the letter chart. Yearly eye exams are crucial to ensure that development is on the right track!
In case you missed it, this is the dress that everyone’s been talking about! Is it blue and black, or white and gold?
To me, it looks like a white and gold dress held in shadow! I can see how the white part looks bluish, but no matter how long I look at it, the lacey frills always look gold to me. Our visual system is so amazing! What does it look like to you?
Ask your friends, and you’ll be amazed by how divided the answers will be!
Here’s an explanation for it: http://www.wired.com/2015/02/science-one-agrees-color-dress/
It has been confirmed that the dress is actually black and blue, but don’t worry if you see it as white and gold – a lot of other people do too, and that picture is very confusing! #blackandblue #thedress
