① Photo Brown/Photo Grey: Lenses do not have anti-blue light function, but have anti-reflection functionLenses will darken in sunlight, turning brown and gray (changing color with the intensity of ultraviolet light) ② Anti Blue Ray+Photo Brown/Anti Blue Ray+Photo Grey: Lenses have anti blue light function and anti reflection functionLenses will darken in sunlight, turning brown and gray (changing color with UV intensity)Relatively speaking, it is more recommended to choose ② ③ Polarized/Color Tint: The lenses are colored and are default black-gray lensesThey are prescription sunglassesIf you need sunglasses with lenses of other colors, please contact customer service to choose the color you prefer ④ None: This lens only has anti-reflection function, make prescription glasses according to the prescription on ⑤ Anti Blue Ray: The lenses have anti-blue light and anti-reflection functions, which are our most commonly used prescription glasses I hope these are helpful to youIf you have any other questions, please contact customer serviceWishing you a wonderful day Standard Acrylic aspheric Air Lens Our 1.56 index lenses are thin, lightweight, and impact-resistant CR-39 lenses are up to 17% thinner than the industry standard Plus its: ●Scratch Resistant●UV Protective●Aspheric●Thin●Anti-reflection Aspheric Lenses suggestion power: Myopia- ----- - SPH: -0.00~-3.00; CYL: -0.00~-2.00 Hyperopia---SPH: +0.25~+3.00; CYL:+0.00~+2.00 (ADD $10) Cylinder------CYL: +2.00~+4.00 or CYL:-2.00~-4.00 (ADD $10) Standard MR-8 aspheric lens Our 1.61 index lenses are thin, lightweight, and impact-resistant CR-39 lens is up to 26% thinner than the industry standard Plus its: ●Scratch Resistant●UV Protective●Aspheric●Thin and light●Anti-reflection Aspheric Lenses suggestion power: Myopia- ----- - SPH: -0.00~-6.00; CYL: -0.00~-2.00 Hyperopia---SPH: +4.00~+6.00; CYL:+0.00~+2.00 (ADD $10) Cylinder------CYL: +2.00~+4.00 or CYL:-2.00~-4.00 (ADD $10) Standard MR-7 aspheric lens Our 1.67 index lenses are thin, lightweight, and impact-resistant CR-39 lenses are up to 40% thinner than the industry standard Plus its: ●Scratch Resistant●UV Protective●Aspheric●Ultra thin●Anti-reflection Aspheric Lenses suggestion power: Myopia- ----- - SPH: -0.00~-8.00; CYL: -0.00~-2.00 Hyperopia---SPH: +4.00~+8.00; CYL:+0.00~+2.00 (ADD $10) Cylinder------CYL: +2.00~+4.00 or CYL:-2.00~-4.00 (ADD $10) Standard ultrathin ACR Air Lens Our 1.74 index lenses are thin, lightweight, and impact-resistant CR-39 lenses are up to 60% thinner than the industry standard Plus its: ● Scratch Resistant ● UV Protective ● Aspheric ● The thinnest ● Anti-reflection Aspheric Lenses suggestion power: SPH: -0.00~-12.00; CYL: -0.00~-2.00 Cylinder------CYL: +2.00~+4.00 or CYL:-2.00~-4.00 (ADD $10) Aspheric Lenses undistorted edge, see the things as real ●Thinner●Lighter●Flatter Spherical Lenses distorted edge, distortion Difference between Spherical Lens and Aspherical Lens Generally speaking, spherical lenses are thick and the image through the lens will be distorted Aspherical lenses are thinner, lighter, and more comfortable for wearers Aspherical lenses have a wide field of vision and the image through the lens is more real and naturalWearers will not feel tired after wearing aspherical lenses for a long time Anti-blue lenses: Ordinary lens Blue Reflective Lens DIGITAL SCREEN PROTECTION Help protect your eyes while using devices such as phones, computers, and tablets provide Lenses: 1.56 Anti-Blue 1.61 Anti-Blue 1.67 Anti-Blue 1.74 Anti-Blue Photochromic Lenses: Photo Brown/Anti Blue Ray + Photo Brown/Photo Grey/Anti Blue Ray + Photo Grey indoor Low light Glare LIGHT ADJUST ING (Provide Lenses: 1.56 Photochromic 1.61 Photochromic 1.67 Photochromic) Lenses that darken when exposed to outside light and remain clear inside Optometry Data Explanation : Explanation: 1.OD-RIGHT = Right Eye OS-Left = Left Eye 2. Sphere (SPH)=Spherical, is the strength of our prescription, "+" refers to farsightedness and presbyopia, "-" refers to nearsightednessIf "PL" or "Plano" is stated in the SPH section of your prescription, please enter 0.00 for this option 3. Cylinder (CYL) = Cylindrical, is the diopter degree of the astigmatismThis number also has "+" or "-" signsIf "DS" or "SPH" or "spherical" or "PL" is stated in place of CYL, it means you have no astigmatism and 0.00 is the option required to choose 4. AXIS, is a number between 0 and 180 degrees, and means the orientation of your astigmatismThere is no sign before this number 5. PD-PUPILLARY DISTANCE = Pupillary Distance PD (OU), written as "64", means the Binocular PD which is for both eyes PD (OD) means the monocular PD for the right eye, PD (OS) means the monocular PD for the left eye Please do check the frame size The ruler in the picture cannot be used to measure your old glassesPlease use your measuring tool to check the size of the old pair of glasses(2-3mm difference acceptable) The thickness of the lenses depends on a few factors: 1.Prescription strengthThe stronger the prescription, the thicker the lens, all else being equal 2.Frame selection/fitAll else being equal, the larger the size of the lens, the thicker it gets (thickness is proportional to size) 3.The higher the refractive index, the less of a material is needed to bend or focus the light in the same way for the same purpose prescriptionSo, higher index material lenses will also reduce thickness and the "coke bottle" effect Helps with common discomforts 1.New glasses 2.New Prescription 3.The change in frame shape may cause discomfort 4.Discomfort caused by a mismatch between prescription and lens ex 5.Discomfort caused by the spherical lens First time trying progressive lenses It is of great importance to learn how to use progressive glasses, and it may take several weeks to get used to themIf you still feel uncomfortable after several weeks, you could switch to bifocal glasses or single vision lenses for reading/distance
