Decades later your biography will contain the testimony of how God kept and delivered you in this time of profound vulnerability (vv. What will the final chapters of your life say? That God failed you? Oh, no.

The psalmist, like Hannah in the sting of her broken circumstances (1 Sam. That’s why the psalmist asks God to do something quickly-chronos time is a terrible burden and tedium. When you are in emotional pain, there’s no kairos-your life is so burdened that each second seems as an hour, each minute a day, each day a month, and each month a year. It can be so enjoyable you lose track of chronos time altogether. Chronos time is the endless tick-tick-tick of the clock, chronological progression, the long wait for something wonderful or dreadful.īut kairos time is a season. The Greeks had two words for time: chronos and kairos. A handheld device, that can be worn around the neck and picked up as needed, may also be a convenient option if the hands are otherwise available and not using a cane, walker, or carrying packages for instance.You hope God hasn’t turned His back on you and that He will answer quickly (v.
Tunnel vision meaning full#
Positioning the FE in full diameter position means it will be in the way when not needed, so the flippable SightScope option may be compelling because it can be moved in and out of position as needed. So, a straight-ahead (full diameter) position, or perhaps even a downward position should be considered, because that’s where all the ‘action’ is likely to be. They’ll have to tilt their head too far down to be able to see the floor. So, positioning the field expander in the top of the carrier lens in bioptic position may be ergonomically inconvenient.

Where is the individual likely to be looking to insure their safest mobility? They’ll be looking downward most likely. Let’s assume that your patient appreciates the benefit of the visual field doubling. They can be positioned in front of eyeglass lenses without significantly impacting their field of view (as compared to telescopes that need to be positioned through the carrier lens to maximize their field of view), and they don’t need to be focused. They are not very vertex distance sensitive and they have very broad depths of field. There are, however, some convenient optical characteristics of FE and IM devices. As a result, currently available optical field-enhancing devices are only available with a 50% image size reduction factor. Greater amounts of image minification will cause the content within the reduced image to be even less discernible, and hence less likely to be helpful for the individual. So, an individual who may have best-corrected visual acuity (BCVA) of 20/40, will, with a 0.5x minification device, now have a visual acuity equivalent of 20/80. Why not provide greater image minification than 50%? Once a patient has significant visual field constriction, there is usually also some concomitant reduction in visual acuity.
