Progressive Replacement Lenses
Material Notes: 1.67 High Index Replacement Plastic Lenses
At LensFactory, we strive to give it to you straight, so we use as little optical jargon as possible. We include the things that we know that you want and do not charge extra for them, such as:
We see many lens providers charging extra for scratch coatings, even on Polycarbonate, which must be scratch coated because it is very soft. Scratch coatings are included on all plastic lenses that we sell, because we know that you don't really want lenses that are easily scratched. Glass lenses have the best scratch resistance and do not require scratch coating.
Another key lens property is UV protection. Polycarbonate and most other lens materials, other than basic plastic and glass, block UV inherently, so charging for UV treatment is just a way to increase the price. You will not find these tactics at LensFactory. Clear glass lenses do not block long wave UV, but photochromic glass lenses do.
Note on Impact Resistance
If the lenses will be worn by children or for sports or safety use, choose Polycarbonate or Trivex lenses which have the highest impact resistance. Impact resistant lenses are not unbreakable and rely on the strength of the lens and frame to provide eye protection.
Our opticians use carefully selected premium lens blanks from Vision Ease, Shore Lens, Somo, Essilor, Varilux, Corning, Zeiss and others. We sift through all of the marketing hype, specifications, and lens designs, and we select the best lenses so that you don’t have to.
Since you are going to send us the frames that you love, there is no need for you to key in your prescription information, just send a copy along with your glasses and our opticians will decode it for you; they specialize in reading doctor’s hand writing! If we see anything with your order or lens selection that needs attention, we will contact you.
What do I do next?
Just add your lenses to the cart and process your order. Request a free shipping kit if you have time, or pack up your glasses, enclose a copy of your prescription and the emailed receipt, and send it to LensFactory. The address is on the bottom of our web page and on the receipt. We will take care of the rest and ship your glasses back to you with new high quality lenses in them.
