An “Eye-Opening” Shift In Classroom Learning
And when you’re not blinking, the tears that are on your ocular surface just evaporate. You’re not distributing new, healthy, clean tears across the ocular surface.” Another thing that can contribute to the dry-eye feeling is the lack of oil being distributed to the eye via your eyelid. “When we blink, we push out a little bit of oil,” Starr said. “It’s critical for healthy tear film.

Eye Study Results May Offer New Therapy for Some Vision Loss
As the use of electronic devices increases, eye doctors are providing age-specific tips and warning signs for parents and teachers to be on the lookout for this school year that may indicate an undiagnosed vision problem or CVS: Preschool/Kindergarten Children: Limit tech time to two hours or less and increase screen font size. During this stage, parents should also be aware of physical signs that may flag a potential vision problem, such as: Improper eye alignment or if one or both eyes turn inward or outward Excessive blinking or eye rubbing when children do near work Difficulty recognizing colors, shapes, letters and numbers.

The fovea is the small, central area of the retina. People constantly move their eyes to aim the fovea at different parts of a scene in order to create a picture of their surroundings, explained the authors of the study published Aug. 15 in the journal Current Biology. “The system that controls how the eyes move is far more malleable than the literature has suggested,” Bosco Tjan, of the University of Southern California, said in a journal news release. “We showed that people with normal vision can quickly adjust to a temporary occlusion [blockage] of their foveal vision by adapting a consistent point in their peripheral vision as their new point of gaze.” Tjan and colleagues simulated the loss of foveal vision in six young adults with normal vision. The researchers did this by blocking part of a visual scene with a gray disc that followed the participants’ eye gaze.
