According to research from Cleveland Eye Clinic Ohio, NOWORDUP Multi-Focus Progressive Lenses reading glasses have been shown to be effective in correcting vision in presbyopia. Studies have shown that it provides better visual acuity than traditional bifocal lenses.NOWORDUP Multi-Focus Progressive Lens Reading Glasses are a type of multifocal lens that corrects vision in presbyopia, a condition that affects the ability to focus on nearby objects. The lens has an angle of increasing power that allows a smooth transition between the two different areas of vision. The anti-bluelight capabilities are proven to help long-term users sleep better at night.Design has evolved over time, with modern lenses using aspherical surfaces to reduce distortion and also improve visual acuity.âDr. Michael Harver, Cleveland Eye Clinic, Ohio. Blue light, like other colors of visible light, is all around you.The sun emits blue light.This also applies to fluorescent and incandescent lamps.Due to the widespread use of devices based on light-emitting diode (LED) technology, people are exposed to more blue light than ever before. Your eye is equipped with structures that protect it from certain types of light.Your cornea and lens protect the light-sensitive retina at the back of the eye from harmful UV rays, for example.These structures do not block blue light.And youre exposed to a lot of it the suns natural blue light far exceeds the amount from any single device.Still, some eye health experts have raised concerns about blue light exposure from backlit digital screens and devices.Thats because people spend so much time using them from such close distances. Blue light-blocking glasseshave filters in their lenses thatprevent or absorbblue light, and in some cases UV light, from passing through.That means if you use these glasses while looking at a screen, especially after dark, they can help reduce your exposure to blue light waves that can keep you awake.Many blue light blocking glasses you can buy also claimto reduce eye strain.Most are designed to be worn during the day while working in front of the computer and at night to prevent the blue light from screens from keeping us awake. NOWORDUPMulti-Focus Progressive Lenses Reading Glassesare multifocal lenses, an advanced type of corrective lenses thatprovide a smooth transition between different focal lengths, enabling vision at different distances.In contrast to conventional bifocal or trifocal glasses, in which the different lens strengths are clearly separated from one another, progressive lenses have a progression of increasing lens strength.This gradient allows for more natural vision correction and eliminates abrupt changes in focus and thejump that occurs with bifocals.Works effectively in different visual phases as follows: Distance View:The upper part of the lens is designed for viewing objects from a distance.It is ideal for activities such as driving or watching TV. Medium vision:As the eye moves along the lens, the power gradually changes to adjust to medium distances, useful when working at a computer or looking at something a few feet away. Close View:The lower part of the lens features the highest magnification, tailored for reading or other close-up photography.
