    Aspheric Lenses :                                                                                        

     

     Aspheric Lenses 
    undistorted edge, see the
     thing as real

     ●Thinner    Lighter    Flatter

     Spheric Lenses

     distorted edge, distortion

     

     
    Difference between Spherical Lens and Aspherical Lens
     Generally speaking, spherical lens are thick and the image through the lens will be distorted. 
     aspherical lens are thinner, lighter and more comfortable for wearers.
    Aspherical lens have wide vision and the image through the lens 
     is more real and natural. Wearers will not feel tired after wearing aspherical lens for a long time.

    Optometry Data Explaination :  

     
     Explaination:
     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 
        nearsightedness. If “PL” or “Plano” is stated at the place of 
        SPH on your prescription, please enter 0.00 for this option.
     3. Cylinder (CYL) = Cylindrical, is the diopters degree of the  
        astigmatism. This number also has “+” or “-” signs. If “DS”or  
        “SPH” or “spherical” or “PL” is stated at the 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 astigmatism. There 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.

     
     
    Thickness of the lenses depends on a few factors.
    1.  Prescription strength. The stronger the prescription, the thicker the lens, all else being equal. 
    2.  Frame selection/fit. All else being equal, the larger the size of the lens, the thicker it gets (thickness proportional to size). 
    3.  The higher the index of refraction, the less of a material is necessary to bend, or focus, the light in the same way for the same  prescription. So, higher index material lenses will also reduce thickness and “Coke bottle” effect.
     
    Helps for common discomforts.
    1.  New glasses
    2.  New Prescription
    3.  The change of frame shape may cause discomfort.
    4.  Discomfort caused by discordance of prescription and lens index.
    5.  Discomfort caused by the spherical lens.
