Understanding focal length in photography - focal length comparison
Enginedisplacementcalculator cubic inches to liters
Telescopes can be placed in any position and at any angle a task demands. For example, a custom telescope was designed for a student who needed one telescope angled down for reading and writing and the other up for seeing the teacher and the chalkboard. Telescopes vary in power, field, weight, focusable and non-focusable. Telescopic optics is very complex. The knowledge and experience of the doctor in designing and fitting is extremely important in determining what is best for you.Cost varies with the prescription needed in the system and the type of telescopes ordered. This can be discussed during the COMPLIMENTARY TELEPHONE INTERVIEW.
Bioptic Telescope spectacles provide the benefits of a telescopic system during activities that require both mobility and better central vision. The telescopic system is available in a variety of sizes, shapes, colors and levels of magnification. They can be made in various types of frames to fit the patient’s needs. The patient and the doctor work together to choose best system for the task and activity requirements. Some of the tasks and activities our patients have used their bioptic glasses for include:

Miniature Binoculars inserted into eyeglasses are called TELESCOPIC SPECTACLES. The patient’s eyeglass prescription, as well as the highest quality optics, must be used in the system for maximum clarity. Telescopic spectacles can be for one eye (monocular) or two eyes (binocular). The telescope can be mounted in various positions in the glasses.

Two telescopes can be “converged” for use at near when reading or performing fine detailed tasks. Telescopes vary in power, field, weight, focusable and non-focusable. Telescopic optics is very complex.
Measuring vibration directly is also easier than ever using the Digiducer. A truly plug-and-play USB accelerometer, the Digiducer can be connected to any portable device like a SmartPhone, tablet or PC. Click here for more information: https://digiducer.com/products/digital-usb-accelerometer
Displacementcalculator with direction
Smaller telescopes mounted high in the glasses allow the person to view through either the telescope or the “carrier”, the regular prescription lens, by simply moving the head slightly up or down.
The following table can be used to calculate the requirements for sine vibration. Acceleration, velocity, displacement and frequency are all inter-dependent functions and specifying any two fully defines the motion and the remaining two variables. Just select the tab with the units you would like to use to begin.
