The reversible design allows switching between a glossy gold side and a black side to suit different needs. With 57.5% light transmittance, the filter ensures optimal screen brightness while blocking up to 51% of blue light to reduce eye strain. It's quick and easy to install using residue-free adhesive strips or side mounting tabs. Highlights: - Enhances privacy from unwanted glances
