The Progressive Lens:also called progressive addition lenses(PAL), progressive power lenses, graduated prescription lenses,and varifocal or multifocal lenses,are corrective lenses used in eyeglasses to correct presbyopia and other disorders of accommodation.They are characterised by a gradient of increasing lens power, added to the wearer’s correction for the other refractive errors. The gradient starts at the wearer’s distance prescription, at the top of the lens and reaches a maximum addition power, or the full reading addition, at the bottom of the lens.The length of the progressive power gradient on the lens surface depends on the design of the lens, with a final addition power between 0.75 and 3.50 dioptres.The addition value prescribed depends on the level of presbyopia of the patient. In general the older the patient, the higher the addition. 2.About Lens Index:We have 1.61 index and 1.67 index lenses.The higher the refractive index,the thinner the lens thickness corresponding to the degree. 3.About Photo Grey Lenses:Indoor is colorless,In the sun,it will be Colorless change to Grey. 4.About Anti Blue Ray:Anti bule light from computer,phone screen light,or TV light,and protect your eyes. 5.About Color Tint:It is tinted color,it is gradient color from top to bottom,it is very light color,It doesn’t affect the use of it.It make the lenses more beautiful,Just decorating,please know it. 6.About None Lenses:Not Tint color lenses,the lenses is colorless(Clear). 7.The Lenses Recommendation: If your Myopia degree is 0 to -6.00,we are recommend 1.61 index lenses.

Or you can like this measurement by yourself like following picture. You can take the measurement 3 times,to get an average and to guarantee accuracy. How do I measure my Pupillary Distance (PD)? 1.Place a millimeter ruler on the bridge of your nose. 2.Have a friend face you about arms length away. 3.Have your friend measure the distance between the center of your pupils (the black dots in the middle of your eyes). 4.Or you can do it yourself simply by looking in the mirror.If you need your glasses on to do this,you can draw dots on the lenses where your pupils are(using a magic marker or highlighter);then take the glasses off and measure the distance between them. It’s simple–like playing connect the dots! You can also get this information from your doctor or from a licensed optician. Take the measurement two or three times to get an average and to guarantee accuracy. As a guideline:

• Most adults’ PD’s are between 58-68mm.
• Most kids’ PD’s are between 45-58mm.
