The most aesthetically pleasing images are all based on the golden ratio. The golden ratio is, put simply, a rectangle a little more than 1.6 times wide as it is high.
According to the theoretical study published in the International Journal of Design and Nature and Ecodynamics, the most efficient proportions for the human eyes to scan is a rectangular shape where the horizontal is about one and a half times the vertical, which Professor Bejan said approximates to the golden ratio.
Squares and Rectangles
These two shapes are thought to be the most commonly used.
Red and orange seem to be the clear winner when it comes to eye-catching colors. These colors tend to stand out and are therefore used on many warning signs or safety equipment. Yellow is another color that comes in a close second to red and orange in popularity.
Summary: The golden ratio is a geometric proportion that has been theorized to be the most aesthetically pleasing to the eye and has been the root of countless mysteries over the centuries.
But the heart shape, otherwise more commonly known as a V-shaped face, has been scientifically proven to be the most visually attractive face shape to have. Heart-shaped faces like those of Hollywood star Reese Witherspoon are deemed as 'mathematically beautiful'.
In comparison to the rest of the animal kingdom, humans have very good eyesight. We can see objects with clarity from far distances, have strong depth perception and can distinguish between up to 1 million different colors.
These colours (yellow, green, orange) are in the middle of the visible spectrum (the range of colours that our eyes can detect) and are the easiest for the eye to see. Our eyes are not as receptive or sensitive to the colours at the extreme ends of the visible spectrum (e.g., blue, violet/purple, and red).
Green, the mixture of blue and yellow, can be seen everywhere and in countless shades. In fact, the human eye sees green better than any color in the spectrum.
Our eyes are most sensitive to yellow and green, so they're the easiest colors for us to see, even when we're not looking directly at them. And even people with red-green color blindness can still see yellow, that's why it's the most popular color for highlighters.
Triangles are the strongest shape.
Triangles are extremely important shapes when it comes to engineering. From bridges to houses, and even airplanes -- using triangles in structures will always be important!
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world's population sports melanin-rich brown eyes.
As the ultimate curvilinear shape, the circle embodies all of the attributes that attract us: it is a safe, gentle, pleasant, graceful, dreamy, and even beautiful shape that evokes calmness, peacefulness, and relaxation.
At some point, you've probably wondered what the rarest eye color is. The answer is green, according to the American Academy of Ophthalmology (AAO). Only about 2 percent of the world's population sport this shade.
Legendary is a soft, gray, millennial beige with a silvery undertone. It is a perfect paint color for a living room or exterior home.
The study found statistically significant gender differences in relation to yellow, white and green-yellow. All three colors were perceived as more attractive by women than by men. Results from our study show that chromatic colors have been perceived as more attractive than achromatic, with exception for black.
Blue. Blue is perhaps the best color for your bedroom. Not only is it more muted, but blue tones also tend to have more calming effects on the brain, as shown in a 2018 study of blue walls in a university residence hall.
Yellow is the least favorite color, preferred by only five percent of people.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Certain colors on the spectrum, like blue light, are harder on the eyes because they have shorter wavelengths and are high energy. Blue light also flickers more frequently on computer screens' LED backlight controllers, and this flickering causes more eye fatigue than other colours like red or orange.
The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
Eagles. All birds of prey have excellent long-distance vision, but eagles stand out. They can see clearly about eight times as far as humans can, allowing them to spot and focus in on a rabbit or other animal at a distance of about two miles.
Mantis shrimps probably have the most sophisticated vision in the animal kingdom. Their compound eyes move independently and they have 12 to 16 visual pigments compared to our three. They are the only animals known to be able to see circular polarised light.
