We offer two types of lenses; the Polycarbonate and the Trivex® lenses. They are both impact resistant and possess 100% ultraviolet (UV) protection built in. Both lenses can be tinted in Gray or Brown in three shades 1 – 2 – 3 with 3 being the darkest.
Both products are available in Transitions and the Polycarbonate is also available in the Polarized form, both products may be coated with anti reflective coating (AR).
Polycarbonate: We use this lens as a minimum standard in all of our prescription and nonprescription glasses. This is an old established product that has been proven to be one of the best for impact resistance being a major concern for us with children.
Trivex®: In the past few years other improved products have appeared on the market such as the Trivex® material which is a denser material and thus offers better visual acuity, resistance to impact and scratching. This product has been proven in drop tests conducted by the optical industry to be twice as strong as the Polycarbonate. Click here for more information.
Transitions: These lenses are treated with a photosensitive agent that makes the lens darker when exposed to sunlight. Outdoors, they offer an attractive tint of gray or brown which quickly fades to clear indoors. Transitions are very practical for infants exposed to outdoor activities or having been prescribed sunglasses.
Polarized: These lenses possess the property of selectively absorbing light wavelengths in certain planes. When light, normally in different wavelengths passes through polarized lenses it transforms into a single linear plane, suppresses reflections and eliminates glare. We recommend polarized lenses for use with the sport frames for any outdoor activity such as fishing, skiing, biking, hiking or bird watching for a crisp vision unencumbered by glare.
We need your prescription information to make your new glasses. We have designed this form to make transmitting this information as clear as possible. Your prescription information allows us to custom make your lenses in your exact prescription.
Please note and pay special attention when entering the plus (+) or minus (-) signs preceding all sphere and cylinder powers. We also ask that you fax or scan and e-mail your prescription to 650-340-1774 or to email@example.com for confirmation before processing.
The Pupillary distance ("PD") is needed to fabricate your lenses. Oftentimes you will not find this measurement on your written prescription. Your eye care provider should be able to provide you with this measurement. Many of our customers have obtained their PD by calling the last place that they purchased prescription glasses. Alternatively, you can measure "PD" yourself by following these instructions:
- Pupil method
- Canthus method
Note: to measure the PD, you will need a millimeter ruler. If you do not have one, you can print and use this millimeter ruler (PDF file).
