wow thank you so much :)) When I requested that video, I thought you will never do it so it's such a great surprise and excellent ping-pong eye trick!! You're a magician and a doctor in 1
Hello i been assigned to a meeting with a doctor next monday but since i stumbled onto your channel i just wanna ask some questions about this trouble i have been going through the past 3 years my testicle seems to swell up on random occasions and sometimes the pain can get so severe my whole body goes into toxic shock now its gotten throught this whole week of uncomfortable feelings or pain if possible i felt around and noticed my one testicle feels no pain as i press against the cords mind You this pain has only affected my left testicle the right one had no pain or feeling at all but the left one feels tender idk what to do or anything i believe i have testicular cancer or a hernia but im not waiting a week for a doctor to tell me that im in too much pain everyday please respond back and thank you for reading
Let me cover double vision in the distance. Both eyes should point at what I'm looking at. If not, I have double vision. If a dominant left eye points at the object and the second right eye is pointed to the left of the object there is double vision, the object being situated to the right of where the right eye points. The effect is an image to the right of the one the dominant is on. (100% sure.)
At 2:10 he begins talking about the eye. I thought it was relaxation of the ciliary body that causes flattening of the lens. It's contraction of the ciliary body that actually causes the lens to become flat to focus on distant objects. Relaxation of the ciliary body--> flattened lens for distance vision. Contraction of ciliary body--> fatter lens for near vision.
It's the interaction between the ciliary bodies and zonules that causes lens shape change. So contraction of ciliary bodies causes relaxed zonules and a fat (convex) lens for near vision. Relaxation of ciliary bodies causes taut zonules, which causes flatter lens for distance vision.
Hai, May i use Convergence eye exercise (using pencil) to reverse my presbyopia? Hope you knew, Muscle stiffness is presbyopia. Can I relieve muscle stiffness using Convergence eye exercise ?
I literally love you for your great, humble, funny unforgettable explanation. Thank you.
One of the best UA-camrs ever
Very simple and clear , and even funny
I used to hate anatomy but with ur videos u have made me love it
Huge THX ❤❤😍
Great review.
Of course both accommodation and convergence are accurate control systems.
Thank you so much for this informative explanation on eye anatomy (& the causes to certain diagnosis).
wow thank you so much :))

Hi, I don't have this issue but I am curious if you found out what the issue was
amazing video !
Great as always :)
So if u fail to converge ..eye goes out when trying to converge.. Is it due to a weak medial rectus...or overzealous lateral rectus?
thank you !

Hallo Dr. Webster, where can I buy the same eye model?
God I love this guy
Super thank you 🙂🙂🙂
Is there also a video about the magic that happens in the brain?
Powerful

A convex lens magnifies. For distance vision the lens is relaxed. Surrounding muscles compress and fatten the lens for close up viewing.

The lens is relaxed for distance vision. A crystallized lens would not permit close focus.
Perfectlyyyyy perrrrfect
He is so funny n down to earth
