• Can I use old lenses from to fit my new frame?

  Probably, you can do it like this, but you should carefully choose the frame that can fit your lenses well. The frame only holds the lenses and the lens is mounted in such a way that the centering is exact to your iris.Otherwise, the lenses may pop out or give you an unclear vision. It is much easier for you to get another new pair of glasses.

  PD stands for Pupillary Distance, which is the distance between your pupils in millimeters, Your PD is very important for accurately fitting your lenses to achieve vision acuity. 1. PD (OU), written as ""62"", means the Binocular PD which is for both eyes. 2. PD (OD), means the Monocular PD for the right eye, PD (OS), means the Monocular PD for the left eye, A Monocular OD is written as two numbers, for example ""32/30"", ""32"" represents the PD for the right eye, and ""30"" for the left eye. 3. Sometimes PD is written as ""62/59"" or they are labeled ""Far"" and ""Near"". Your PD is usually measured for distance vision, which is 'Far PD"", or ""62"" in this example. For reading glasses, doctors measure your ""Near PD"" or ""59"" in the example. 4. Always enter your ""Far PD"" for distance vision eyeglasses and enter your 'Near PD"" for your reading glasses only. For most people, the difference between Far PD and Near PD is about 2-3mm. Source: http://www.firmoo.com/help-p-30.shtml

• Can I use my contact lens prescription to buy my eyeglasses?

  The answer is definitly NO. Eyeglasses are usually placed at about 12 millimeters away from the eye while the contact lenses are placed directly on the tear film of the eye, the prescription on the contact lenses should be less nearsighted than that of eyeglasses. You can go to your eye doctor to have your eyes checked to see the exact difference.

• Is there any place I can Buy Lenses Only To Fit Into My Old Glasses Frame?

  You can take your glasses to the local optical store and find the lenses are fittable for your old frames, then ask the optician to process it for you, but I think some of them are unwilling to do so for they will take a risk of breaking your old lenses when getting them out and putting new lenses in. Actually, it is also hard to find lenses that are available for your old frames, the best way to slove your problem is to buy another pair of glasses.
