Lens prices vary by lens type, brand, and prescription. In the option, we have a “prescription from” Korean anti-reflective lenses with a 1.56 index spherical design for $ 20. If you want to choose another brand of improved quality lenses for an additional fee, or, for example, lenses with computer protection (blue light blocking lenses), if you need lenses with thinning and aspherical design, write to us and we will advise you on lenses and write you prices. To order lenses according to your prescription, we need information: • Right eye • Left eye • Pupillary distance (PD) measures the distance between the centers of your pupils. This measurement is used to determine where you look through the lens of your glasses and should be as accurate as possible. Demo lenses. For demonstrative purposes in retail scenarios, spectacle frames are fitted with what are called demo lenses. This is done to simulate corrective lenses, simply to give you an idea of what the frame will look like in a more realistic aesthetic. Demo lenses are made from cheap plastic. Demo lenses may contain minor defects. CR lenses without coating were made of a polymer resin called CR39. CR lenses are more comfortable for the eyes and better demo lenses. Anti-reflective coating (also called "AR coating" or "anti-glare coating") improves vision, reduces eye strain, and makes your eyeglasses look more attractive. These benefits are due to the ability of AR coating to virtually eliminate reflections from the front and back surfaces of your eyeglass lenses. Blue light blocking lenses have filters that block or absorb blue light. Natural blue light from the sun helps keep you awake and regulates your circadian rhythm. But indoors, unwanted blue light is emitted from digital devices such as computers and smartphone screens. Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight. Sun fake or prescription lenses with polarization or anti-reflective are the best protection from glare and eye strain on sunny days. These lenses have a special filter that blocks bright reflections of light from water, sand, pavement, automobile hoods, and windshields.   Frames with demo lenses are subject to return from the date of receipt of the parcel for 14 days. Frames with CR, Anti-reflective, Blue light blocking, and Photochromic lenses are considered custom orders and cannot be returned. Every pair of our eyewear comes with a hard case and silk cloth. We Use Hard boxes to Protect the Items So That During Shipping there are fully protected. After shipping, you will receive a tracking number. So you can easily follow your parcel and check the status online. If you have any questions feel free to contact me and I will answer them ASAP. Guys, we’re happy to present our new winter project.
