UV 420

eyeglass lenses

Harmful blue light emitted by laptops, smartphones, televisions, LED, and fluorescent lighting can adversely affect our health. Prolonged use of such devices can cause headaches, eye strain, poorer sleep quality, and increased risk of certain diseases such as diabetes, heart disease, or obesity. Additionally, high-energy visible light (HEV) or blue light can penetrate deep into the eye and lead to retinal damage and cell death in the macula.

Standard eyeglass lenses with anti-reflective coatings do not sufficiently protect the eyes from the harmful effects of blue light generated by electronic devices. Therefore, individuals whose work or hobbies involve spending long hours in front of such devices should consider glasses with blue light filtering.

UV 420 eyeglass lenses provide protection by blocking 100% of UV radiation (up to 400 nm) and up to 90% of harmful blue light (up to 415 nm), while maintaining 85% transmission of beneficial blue light responsible for melatonin production – the sleep hormone. An advantage of these lenses is also the absence of color distortion for the wearer. UV 420 eyeglass lenses not only improve visual quality but also protect the eyes and promote relaxation, even during focusing on close distances.

UV 420 eyeglass lenses are dedicated to individuals who spend a lot of time at the computer and will also be an ideal solution for computer gamers or electronic gadget enthusiasts.

Everyone, not just those with vision problems, should consider glasses with blue light filters because over time, the effects of blue light can worsen the condition of our eyes and affect visual quality.

The special UV 420 blue light filter can be applied to corrective glasses, starting from single-vision lenses through bifocal lenses, relaxation lenses, office work lenses, up to progressive lenses, and is suitable for every type of vision impairment.
