About this deal

PD is marked as two values '62/59'. 62 is your distance PD, which can be used when you need single-eye distance glasses, bifocals and progressive glasses. 59 is your reading PD, which can only be used when you need monocular reading glasses. (The reading PD is usually 3mm smaller than the distance PD, because the eyes will be close when reading.) You can easily measure PD at home, especially when you are with friends or family. If you are wearing glasses, remove them and look 10 to 20 feet away. Light from the darkness. Color can affect our mood. The important thing is to find the connection. Sunny colors depict a rainbow of hope, and classic colors create a calm and stable atmosphere. Organic fashion

Shape: Whether its rectangular, aviator, round or cat-eye, choose something to compliment your style and features. PD stands for pupil distance, which is the distance from the center of one pupil to the center of another pupil. PD is an important factor. It tells you where you look through the lens of the glasses. This is especially important for people with high prescriptions, because it is one of the important parameters of lens prescriptions. For Reading-only correction, there should always be a value under sphere and most of the time it is positive. If there is a value under Near Vision (N.V., N.V.O.) then enter the power in the BOTTOM half of the form and leave the ADD power blank or ('0.00'). Monocular PD refers to the distance from the bridge of the nose to the pupils on both sides. It is marked as two numbers around 30mm, such as 31 and 32.Nothing is more free, more carefree, and more energetic than childhood. This mood can make people of all ages better, let us see the world in a more vivid color, let us not be too harsh, let us project ourselves into the world like an amusement park. It is in this context that various voices come together to express their desire to make the future better. This desire is communicated through interesting channels and supported by technology. It is spread through music, fashion and art, and even expressed through virtual reality. Everything is influenced by modern retro style. From patterns to fresh colors, it exudes a retro atmosphere. Bona fide On a typical prescription, you will see two sets of rows. Most of the time top portion is for your OD or right eye while the bottom portion is for your OS or left eye.

For astigmatism correction, please note that that Cylinder (CYL) and Axis are always provided together. For any value of Cylinder there should always be a value for Axis. Some doctors use positive (+) cylinder and some uses negative (-), there is a big difference between the two so please pay close attention to the positive and negative signs. If you don't have astigmatism correction, doctors might just leave it blank or simply SPH or DS which means Sphere or Diopters Sphere. Axis should be from 1-180 degrees, if you see a value like '5' under axis, this is also the same as '005' or '5 degrees'. It should always be a whole number and there should no be decimal point on the axis.

Repeat the measurement several times to ensure that the value is more accurate. Binocular PD is represented by a single number, such as '62', which means the total distance between your pupils. This is the standard way of writing. The choice here is pretty simple, whether you’re shopping for eyeglasses or sunglasses you have to choose: buying prescription glasses online or getting non-prescription (also called plano).You can usually find PD on prescription drugs. In general, the number of PD in adults remains constant throughout the year, with an average PD range of 57-72 mm.
