  • Publication number: 20160178937
    Abstract: A digital measurement system and method for optical applications including a mobile client device having a digital camera and an audio port, and a laser measurement device having a laser. The laser measurement device connected to the mobile client device and electrically connected to the audio port of the mobile client device. The mobile client device is configured to activate the laser at the same time as the digital camera is activated, and capture an image of a patient. The mobile client device is configured to access a measurement module to calculate position of wear measurements based on a location of a laser mark in the captured image.

  • Patent number: 9360686
    Abstract: A digital measurement system and method for optical applications including a mobile client device having a digital camera and an audio port, and a laser measurement device having a laser and a magnetic card reader. The laser measurement device and the magnetic card reader are electrically connected to the audio port of the mobile client device. The mobile client device is configured to activate the laser at the same time as the digital camera is activated, capture an image of a patient, and calculate position of wear measurements based on a location of a laser mark in the captured image. The mobile client device also allows an order for a frame and lenses to be submitted to an ophthalmic laboratory, and payment transactions to be processed using the magnetic card reader.

  • Publication number: 20070138667
    Abstract: A composition adapted for use in an in-situ coating process for coating an optical surface for ophthalmic applications. A coating composition according to the present invention includes at least one multifunctional acrylate compound which is cured onto a heated surface with controlled coating distribution in an ophthalmic injection mold. For example, the composition may include an acrylic base cured with an initiator, e.g., t-butyl perbenzoate, and may further include at least one catalyst and at least one metal salt. An acrylic base according to the present invention may include a combination of monofunctional and/or multifunctional acrylate and/or methacrylate compounds.
