1x magnification Laser rangefinder BIX technology Dual Stream Video Cons: Not head mountable This model was picked as a favorite for its 1-10x magnification. It comes with a soft-carry case and neck strap to be worn like binoculars, but with 1x power, can it be mounted to head or helmet...
An otoscope lens attached to the direct ophthalmoscope handle provides useful low-level magnification of the anterior segment. Alternatively, an inexpensive head loupe can be used in the field (Optivisor). 7 Medical records should thoroughly document all findings, even incidental ones. Many practition...
The slit-lamp magnification was set at 10×, the background illumination intensity was kept constant with the cobalt blue light and a Wratten 12 yellow filter [27]. 3.6. Ocular surface staining with fluorescein and lissamine green On Day 0, 35, and 84, corneal integrity was assessed by ...
The upper lid should be over the superior lens edge for maximal comfort (figure 2). When the lower lid is excessively low, the zone of near power is too low for easy translation and this will likely result in poor near acuity. 1. In this patient, we can clearly see mixed blepharitis ...
Recent technological advances have led to the development of industrial-grade smart contact lenses, such as the Sensimed TriggerFish lens and the Google smart contact lenses. These devices allow for (1) the continuous monitoring of intraocular pressure (IOP) or biomarkers (e.g., glucose) in tear...
and if the resulting image is of sufficient quality. Adjustments are made to the radii of the surfaces to obtain the desired magnification power. Then an optimization program can be utilized to modify the radii of the surfaces and the thicknesses of the components to improve the image quality ...
