If you use a coma corrector with newtonian optics, and eyepieces fully-corrected for astigmatism, then adaptive optics becomes an unimportant thing for visual use. It's really only important for astrophotography, where the length of the exposer blurs the image with averaged seeing. With the 1/...
How does astigmatism affect the way the perceptual system works? NREM sleep is characterized by what? What is the most likely cause of a 45-year-old male needing eyeglasses to read properly? Why does group polarization occur? How is posture affected by the vestibular system?
Does diabetic retinopathy start out affecting only one eye? Does macular degeneration cause blurry vision? Why does astigmatism cause headaches? Why does the optic nerve cause the blind spot? Is posterior vitreous detachment linked to anything else? Does wet macular degeneration affect both eyes? Doe...
“The shape causes irregular astigmatism, which cannot be corrected by glasses or even contact lenses in its severe stages,” Dr. Mark Mifflin, professor of ophthalmology at the University of Utah, said on the university's The Scope radio segment. Normally,gas permeable contact lensesare a tempo...
I think the Vision Pro was something more akin to the Newton– somebody had a big idea to change the world, the way Apple always does, and people at the company got really excited and invented a bunch of new technology to make it work, but it ended up too expensive for the mark...
in respect to eyes, when we do have afterimages, how does it work and why does it happen? Identify the highlighted part. What is mechanical deafness? How is it different than neural deafness? What is an example of how the body uses a physical sensory organ to enhance perception? Wh...
Contact lenses are usually used by people with vision disorders, such as nearsightedness, farsightedness, or astigmatism. They can also be used to correct vision for people who wear glasses but still experience problems with their eyesight. The importance of contact lenses...
How does this improve vision when the problem is caused by the shape of the lens or eyeball? How does the brain develop a map of the visual field? Discuss the causes of near-sightedness and far-sightedness. Discuss myopia, hyperopia, presbyopia, and astigmat...
The tapetum is not a part of human eyes, but cows' eyes, cats' eyes and other animals' eyes do have tapetums. What does the tapetum do? Why don't humans have them?What is the cause of astigmatism?In the eye, what provides black and...
What role does the fovea centralis have in vision? Discuss the causes of astigmatism. What structure of the eye accommodates for near vision? What is the difference between rods and cones in the eye, particularly in regard to the fovea? Discuss the causes of near-sightedness and far-...
