Considering this study, it's clear that, literally, we see the world around us more clearly when we're happy.

Colored lens

The world seems a little better when we wear red and rose-colored glasses because these glasses increase the wearer's depth of field and enhance detail. The world becomes clearer and brighter.

Other colored lenses have different effects on our vision. We've written more on this topic in our last post on colored lenses, but here's a quick review:

Green lenses: Filter blue light. Suitable for golf and tennis.

Grey lenses: Reduce glare, especially on water. Ideal for fishing and driving.
Blue or purple lenses: Enhance contours while reducing reflective glare. Ideal for foggy weather.
Yellow, orange or gold lenses: perfect for depth perception. Suitable for outdoor and indoor sports.

Amber or brown lenses: Contrast with the green landscape and blue sky. Suitable for sports such as golf and baseball.

With this information, it makes sense to use different shades for different situations.

As mentioned earlier, pink lenses can improve contrast, improve depth of field, and even reduce blue light effects. But sometimes rose-tinted glasses can work against us

The red flag was not visible through rose-colored glasses

Some people expressed concern that red or dark rose-colored glasses could be dangerous. Heavily Shadowed lenses can make warning signs difficult to see. For example, red lights and stop signs. The red color of these signals is intended to make them more visible to prevent accidents. The effect was attenuated when viewers wore glasses with dark pink or red lenses.

This brief arrival has not gone unnoticed in its symbolic form. Warnings about the dangers of looking at the world through rose-colored glasses are often seen in popular culture. For example, in Seann Bowe's song "Hate You," the singer laments, "You can't see red flags with rose-colored glasses." Similarly, in the popular adult animated web series Bojack Knight, Wanda the Owl says, "You know, it's funny: When you look at someone through rose-colored glasses (eyeglass mart), all the red flags look like flags."
