Pattern glare

Do you ever feel like the bright colors or patterns on a shirt or a wall hurt your eyes and give you a headache? If yes, then that is what is called pattern glare. It's like when a bright light shines in your eyes and you squint or close them to avoid the pain.

Now, imagine that the bright light is a pattern or a colorful design, and every time you look at it, it hurts your eyes and makes it hard to see clearly. That's what pattern glare does. It makes it difficult to focus on what you want to see, and you find yourself squinting or looking away a lot.

Some people feel pattern glare more than others, and it can be caused by things like looking at a computer screen for too long or being in a room with lots of bold patterns or contrasting colors.

To reduce the effects of pattern glare, you can try adjusting the lighting in the room or wearing sunglasses with tinted lenses. You can also try avoiding things that trigger your pattern glare, like screens, bright lights, or patterns with high color contrasts.

So remember, pattern glare is when bright colors and designs make it hard to see clearly, but there are ways to reduce its effects and protect your eyes.
