Prescription Values
Prescribed optical values determine the correction required.
Lens Solutions
A prescription lens is made to provide optical correction based on prescribed powers and fitting information. Lens design and frame choice should work together.

Direct Answer
They are lenses manufactured to match prescribed optical values and the fitting requirements of the chosen eyewear.
Prescription lenses can be single-vision, multifocal or other designs depending on the prescribed correction and use. The correct choice depends on a valid prescription, fitting measurements, frame geometry and the wearer’s visual tasks—not just on coating names or lens marketing.
What To Consider
The prescription itself is only one part of the final lens configuration.
Prescribed optical values determine the correction required.
Single-vision and multifocal designs serve different focusing needs and have different fitting requirements.
Frame size and shape can affect lens thickness, usable zones and final positioning.
Material and optional surface treatments should be selected for practical use, compatibility and care.
Before You Decide
Before ordering, understand what is being recommended and why it fits your use.
Ask which distances or tasks the lens is designed to support.
Confirm that required measurements are taken for the chosen frame and lens design.
Ask how to clean and handle the finished lens, especially if coatings are applied.
Prescription values and eye-health decisions should come from a qualified eye-care professional. Pure Optics website content is general educational information.
Lens FAQ
Prescription lenses are the corrective lens components; prescription glasses are the complete eyewear combining those lenses with a frame.
Lens thickness depends on prescription, material, frame size and lens design. A stronger prescription can influence thickness, but it is not the only factor.
Coatings modify surface properties; they do not replace the underlying prescribed optical correction.
Correct positioning helps align the optical design of the lens with the wearer and chosen frame.
