Big discoveries are often made by accident! Don McPherson was working on tinted lenses to protect the eyes of surgeons, until his friend found a very different use for them 😉 Here’s a cool episode of Planet Money on how Enchroma lenses were developed.

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! 🤩

It’s #NationalSunglassesDay and it’s going to be a scorcher 💥, so remember your sunglasses this weekend and year-round! 😎
Not all sunglasses are created equal, so make sure you invest in lenses that have proper UV protection. Come in to Whitby Vision Care: Drs. Schmitz, Sujo, Andrews & Sivasegaran or Brooklin Vision Care: Dr. Schmitz and Dr. Sujo, Associates in Optometry and talk to our helpful associates if you have any questions!

When kids hear a story through audio only, they strain to understand. When they watch an animation, their visual and audio perceptual networks are firing, but there’s not enough integration between them. This requires the most energy for the kid to figure out what everything means. Comprehension was lowest in this condition.
When kids hear a story with static illustrations, there is more connectivity between all the networks, such as visual perception, imagery, language, andsomething called default mode (internal reflection of how the story matters to you). This improves their understanding of the story.
However, the best conditions are reading on mom or dad’s lap! 😊 Nothing comes close to that physical closeness and bonding. 😍
But if things get busy and you need to supplement with a device, try to find simple, illustrated ebooks with narration, rather than animations, or audio-only.
