Excerpted from an article by Natalie Wolchover at www.LiveScience.com If you swapped your eyes for an eagle's, you could see an ant crawling on the ground from the roof of a 10-story building. You could make out the expressions on basketball players' faces from the worst seats in the arena. Objects directly in your line of sight would appear magnified, and everything would be brilliantly colored, rendered in an inconceivable array of shades. The more scientists learn about eagle vision, the more awesome it sounds. Thanks to developing technologies, some aspects of their eyesight may eventually be achievable for… Read more
Herman Snellen was a Dutch ophthalmologist who devised an eye chart in 1862 to test a person’s visual acuity. This Snellen chart is still used today, in several versions. It consists of rows of letters which decrease in size but increase in number with each descending row. A person standing 20 feet from the chart who can clearly read the sixth row down is said to have 20/20 vision. If a person standing 20 feet from the chart cannot read this line, but can read the line 3 rows higher, he/she is said to have 20/40 vision. These letters are… Read more
M&S Technologies has long been a supporter of Pediatric Ophthalmology. In honor of the upcoming annual meeting of the American Academy of Pediatric Ophthalmology and Strabismus (AAPOS) in San Antonio, we're highlighting some basic info related to children's eye care. • Amblyopia ("lazy eye") is poor vision in an eye that may appear to be normal. Two common causes are crossed eyes and a difference in the refractive error between the two eyes. If untreated, amblyopia can cause irreversible visual loss in the affected eye. Amblyopia is best treated during the… Read more
New research suggests that there could be health hazards associated with consuming excessive amounts of beta-carotene. This antioxidant is a naturally occurring pigment that gives color to foods such as carrots, sweet potatoes and certain greens. It also converts to vitamin A, and foods and supplements are the only sources for this essential nutrient. But scientists at Ohio State University have found that certain molecules that derive from beta-carotene have an opposite effect in the body: They actually block some actions of vitamin A, which is critical to human vision, bone… Read more
Legend has it that baseball great Ted Williams could see the seams on a baseball coming toward him at 95 mph and read a record label spinning on a turntable. The New York Yankees' Jason Giambi has said he recognizes the pitch the moment the ball leaves the pitcher's hand. Most hitters, players estimate, pick up the pitch at a distance of 30 feet, about halfway from mound to plate. Today's top athletes incorporate eye conditioning exercises into their workouts to gain an edge over the competition. In recent years, sports… Read more
We've recently added a new protocol to the Smart System: The ColorCheck Color Vision Test. Easy to use and completely randomizable, the ColorCheck screening will effectively test for color deficiencies in patients of all ages. Color blindness isn't blindness as we know it. It's more aptly called a color vision deficiency (CVD): the inability or decreased ability to see color, or perceive color differences, under normal lighting conditions. Color blindness affects a significant number of people. Total color blindness is much less common than partial color blindness. There are two major… Read more
