Is blue lens harmful for your eyes?

Blue light lenses are designed to filter out a portion of blue light emitted by screens and artificial lighting, which some studies suggest may contribute to eye strain and discomfort. However, research on the long-term effects of blue light exposure is still ongoing, and there is currently no conclusive evidence that blue light itself is harmful to eye health. Wearing blue light filtering lenses can be beneficial for reducing digital eye strain, particularly for those who spend long hours in front of screens. Overall, they are not harmful but can aid in comfort during prolonged screen use.
