uv420 blue cut lens are specially designed lenses that help you avoid or delay the onset of Age-Related Macular Degeneration (AMD) by absorbing anywhere from 10% to over 90% of harmful blue light that is visible with high energy in the range of 380 nanometres to 495 nanometres.uv420 blue cut lens This prevents eye strain, normalizes circadian rhythms and makes the eyes more comfortable. These lenses are also a great solution for those who suffer from digital eye strain due to long hours of working on computers or mobile devices.
It is a unique combination of an anti-reflective coating and a blue filter, which protects you against the harmful effects of High Energy Visible (HEV) light emitted by electronic screens such as tablets, smartphones, computers and TVs.uv420 blue cut lens This special coating blocks the transmission of harmful blue light, while still allowing for a good portion of the beneficial blue light that is responsible for the production of melatonin, the sleep hormone. In addition, these lenses do not interfere with natural color perception.
The blue-light-reducing pigment is actually added to the lenses before the casting process and is not merely a tint or coating, making the lenses much more effective at blocking this damaging light than conventional anti-glare glasses. These lenses are also incredibly clear with no colour distortion, making them ideal for everyday use.
These lenses are also available in a wide range of prescriptions, from single-vision to bifocal and progressive lenses and can be customised with any frame design you like. They can also be made as rimless, coloured or clear sunglasses. These lenses are recommended for those who spend prolonged periods of time indoors using electronic devices or on the road, such as drivers and cyclists who work very early in the morning (low light) and late in the day when it is brighter outdoors.
Studies have shown that continuous exposure to HEV light from digital devices, especially the Blue Light that falls within the 415nm-455nm band of the spectrum, can lead to a variety of health problems such as dry eyes and blurry vision, increased risk of macular degeneration, poor sleep patterns, headaches, and insomnia. In children, it is also possible that these symptoms may be contributing to the rise in myopia (nearsightedness) observed since the COVID-19 pandemic. However, further research is required in this area to establish whether the use of blue-light lenses in young people could have unintended consequences on ocular axial length development through the Purkinje rod-cone shift. This is a complex biological process that is currently under intense investigation.
