And, if you've been following the narrative lately, this is the sort of 'technical concept' that you get when you combine a neck brace, a GPS track and a needle (with a built-in ultrasound). Accurate localisation of a neck lump, one-time firing and efficient sample extraction, minimisation of pain to the patient and reduction of operator dependency... as arguably most of the steps could be automated. And, that's what our primitive 'looks-like' prototype actually looked like. We used stop motion photography to depict how sample extraction would work. This was the phase where our team had transitioned from the identification of unmet needs and concepts, to the technical phase of 'inventing'... And while not without its challenges, our prototype helped us to test our ideas for something new... giving shape and form to our dreams. As good prototypes do! #medtechmatters #thejourney

It's no secret that I LOVE #transitionslens (Transitions Optical). Check out one of my favorite #optometrist, Jennifer Chinn, O.D., share her personal experience with Transition lenses. Learn more https://lnkd.in/etqcDTY7 #transitionspartner #optometry #transitionslenses

Dave Blake, PhD, CFVT Aaron Cowan Jeff Martin, JD, MS, CFVT Steve "Pappy" Papenfuhs Geoffrey Desmoulin, PhD RKin PLEng Karl Rehn Joseph Hamilton Help me think through this thought experiment. Researchers wanted to know if pistol marksmanship improved when shooters used a miniaturized red-dot sight (MRDS) versus traditional iron sights. Novice shooters shot a static qualification course twice: once using a pistol with iron sights and once using the same pistol with the addition of a MRDS (e.g., Holosun, Trijicon). All drills were initiated using a shot timer and the time of all shots was recorded. Marksmanship was measured in terms of shot time and accuracy/precision. Compared to iron sights, shooters fired their first shot significantly faster and were significantly more accurate/precise when they used the MRDS. The researchers attributed the better marksmanship to shooters’ use of the red dot. Assuming that the research was conducted appropriately and that the statistics are valid, do you accept that it was the presence of the red dot that resulted in faster and more accurate performance? Or are there any plausible rival hypotheses to account for the difference between the two conditions? When considered rival hypotheses, assume/accept the following: • The researchers were only interested in performance on the static qualification course. Their research question did not encompass shoot/don’t-shoot decision-making, situation awareness, shooting on the move, etc. • The qualification course was a valid and reliable measure of marksmanship. • The sample size was sufficient to detect a small effect. • Shooters: o  Were males aged 25–30 (or any limited age range). o  Were similar in terms of race/ethnicity/intelligence (or any other individual-difference variable you care to consider). o  Had good visual acuity and no visual abnormalities. o  Did not wear glasses or contact lenses and had not undergone any type of eye surgery. o  Were right-hand/right-eye dominant. • The two pistols were both new, were the same make/model, had the same accuracy, and were sighted to the same point. • The aiming point on the front (iron) sight was the same color/shape/size as the red dot on the MRDS. • The size, color, and intensity of the red dot were constant across shooters. • In this within-subjects design, the order in which shooters completed the two conditions (iron sights, miniaturized red-dot sight) was counterbalanced. • Lighting conditions were consistent for all shooters. • Accuracy and precision are distinct measures; both differed significantly by condition. The purpose of this thought experiment is to collectively develop our ability to think critically about research design. If you reply with your anecdotes/opinions about MRDS, you will have missed the mark. This thought experiment was inspired by: Huck, S. W., & Sandler, H. M. (1979).

Which stereo is best for your sample inspection? Matching your stereomicroscope precisely to your imaging requirements is key to achieving the best possible inspection results.

Myopia occurs when the eye’s axial length, the distance between the cornea and the retina, is too long, or the cornea and lens have excessive curvature. This causes light entering the eye to focus in front of the retina instead of directly on it, resulting in blurred distance vision.

Normal vision depends on a multifaceted, complex process. Light enters the eye through the cornea, where some of it passes through the pupil, the black-appearing opening in the iris, which controls how much light enters the eye. The light then passes through the lens, which works together with the cornea to focus it on the retina, a layer of tissues at the back of the eye that’s made up of cells called photoreceptors that transform the light into electrical signals. From here, those signals are transmitted to the brain through the optic nerve, turning them into the image you see in front of you. When any of these eye parts are damaged, either through illness or injury, blindness can occur. #vision #optometry 360care.com LEARN MORE: https://lnkd.in/gNvbZ2Mc

Absolutely love cataract imaging! The same lens seen 2 different ways. A simple shift in focus and you’re able to visualise the full picture. Here you can see an eye with both cortical and posterior subcapsular cataract. Stay tuned for my upcoming collaboration with Keeler to teach you the way of the slit lamp and give you a head start in your imaging. #optometry
