Cats and dogs vision

Cats and dogs vision

  • If you take a flash picture of your cat or dog, their eyes will get an eerie glow. This is because a layer of their eyes reflects light to let them see small amounts of light more efficiently.
  • Cats and dogs are not colourblind. However, they appear to see the world in shades of blue and yellow. As predators, they don't need to see the difference between some similar shades.
  • Their vision would also be blurrier as they aren't built to process clear images.

Stashed ideas


The other senses of cats and dogs compensate for their visual limitations.

  • Cats can hear the ultrasonic sound that their prey makes, allowing them to find their target even their prey gets out of sight.
  • Cats also use smell to identify people. If you've been gone for some time, your cat may not recognise you immediately when you return.
  • Dogs also have a good sense of smell. A dog's sense of smell ranges from 1,000 and 10,000 times more effective than people.

This skill helps them catch their prey. Most cats and dogs will have difficulty finding still objects close to them, but they can spot subtle movement for up to a half-mile.

While humans field of view is about 180 degrees, our furry friends' field of vision is past 200 degrees. However, the field of view differs depending on the breed.

Animals can see better in dim light because their eyes have more rods than ours, meaning they need less illumination to form a usable picture.

Your strange voice on a recording

Many people feel uncomfortable when they hear their own voice in audio recordings.

Your voice sounds deeper and richer when you speak but thinner and higher on recordings. The reason for the variance is this:

  • When listening to a recording of your voice, the sound travels through the air and into your ears.
  • When you speak, some sound travels through the air, but much of the sound is internally conducted through your skull bones and boosts the lower frequencies.
"Clean" cosmetic products  trend

Some of the ingredients in personal care products are not ideal.

"Clean Beauty" products list supposedly ethical qualities ranging from cruelty-free to fragrance-free to formaldehyde-free. But without regulations to back up the word "clean", the term "clean beauty" could be greenwashed.

How "Fashion Week" Started

There are three ways of interpreting when each "fashion week" started.

  1. When fashion shows started to become assembled seasonally.
  2. When the phrase "fashion week" began to be used.
  3. When an organisation began organising these shows.
