Yes, it is bad to look at the sun, even when it's cloudy.
Even though clouds may dim the sun's intensity, they don't block all of its harmful rays. Looking at the sun, regardless of cloud cover, can still damage your eyes. The sun's ultraviolet (UV) rays can penetrate clouds and cause damage to the cornea, lens, and retina.
Here's why it's dangerous:
- UV Radiation Penetration: Clouds reduce the intensity of visible light, but they don't completely block harmful UV radiation. You may not feel the same level of discomfort or glare as on a sunny day, but the risk of eye damage remains.
- Cumulative Damage: Eye damage from sun exposure can be cumulative. Even brief glances at the sun over time can increase the risk of long-term problems such as cataracts and macular degeneration.
- Lack of Discomfort: On cloudy days, the reduced brightness might make you think it's safer to look at the sun, but this false sense of security can lead to prolonged exposure and increased risk.
Therefore, it's always recommended to avoid looking directly at the sun, regardless of cloud cover. Wear proper eye protection like sunglasses that block UV rays when outdoors, especially when the sun is strong.
