General Disclaimer
The information provided by LensOpt (“https://www.lensopt.com”) is for general informational and educational purposes only. We share it in good faith, but we make no warranty of any kind about the accuracy, completeness, or suitability of anything on the site for your particular eyes, prescription, or eyewear.
Any use of the calculators and content is at your own risk. It is your responsibility to confirm that a result fits your specific circumstances before you rely on it.
Estimates, Not a Prescription
LensOpt’s tools produce educational estimates from the numbers you enter and standard optical formulas. They are not a prescription, a contact-lens fitting, a dispensing, or a medical assessment. A pupillary distance for a dispensed pair should be measured by an optician; a contact-lens power depends on the fit and health of your eye; lens thickness depends on the frame, decentration, and the lab; and the right sunglass tint depends on your needs and local law. Before you order glasses or contact lenses, or act on anything that affects your vision, verify the figures with a qualified eye-care professional.
Not Professional or Medical Advice
Content and tools on LensOpt — including the PD, vertex distance, frame fit, lens thickness, sunglass tint, and contact-lens cost calculators — do not constitute professional optical, optometric, ophthalmic, or medical advice. For decisions that affect your sight or eye health, consult the appropriate qualified professional:
- Prescriptions & eye health: an optometrist or ophthalmologist for an eye exam, your prescription, and any symptoms or conditions.
- Dispensing & fit: a dispensing optician for measuring your PD, fitting frames, and choosing lens types, materials, and coatings.
- Contact lenses: an eye-care professional for a contact-lens fitting and the wear and replacement schedule that suits your eyes.
Why Results Vary
Actual outcomes can differ from an estimate because of:
- Your eyes and prescription: real measurements taken by a professional differ from figures typed into a tool.
- Frame and lens choices: shape, base curve, decentration, and lab minimums all affect thickness and fit.
- Your inputs: a flipped sign on a lens power, a millimetre reading, units, and rounding all change the result.
- The market: lens material, brand, and retailer move real prices well beyond any single estimate.
A Note on Sunglasses and UV
The sunglass tint tool reports a filter category from a light-transmission percentage. Tint darkness is not the same as UV protection: a lens of any category should still block UV (look for UV400 or 100% UVA/UVB). Category 4 lenses are too dark for driving. Follow the manufacturer’s markings and local law.
