Block Harmful Blue Light - Our products filter harmful blue light from digital screens which can cause insomnia, eye strain, headaches, dry eyes and blurry vision, with children and teenagers particularly at risk. | 100 Day Money Back Guarantee - If you're not completely happy, send your Ocushield product back for a full refund. We're committed to a healthier, more productive you! Ocushield products are also available for a variety of phones, tablets, laptops and screens. | Privacy Filter - Not only do our products protect your eyes and sleep, our monitor screen protectors include a privacy filter to keep those prying eyes away, plus oleophobic coating to ensure your screen is protected from grubby fingers. | True Colors - Ocushield protects your eyes and sleep, but still allows non-harmful light through the screen, meaning no retro orange tinge - just a full colour crystal clear screen. | Research LED & Developed in the UK - Created by Optometrists, Ocushield is an effective blue light filtering screen protector limiting harmful UV & blue light emitted from screens.
