Eye Anatomy | Dimensions | Axes & Angles Of The Eye
In this session we will learn about the dimensions , axes and angles of the eye.
The structure of the eye is an important topic to understand as it one of the important sensory organs in the human body. It is mainly responsible for vision, differentiation of colour and maintaining the biological clock of the human body. The human eye can be compared to a camera as both works by gathering, focusing and transmitting the light through the lens for creating an image of an object.
Contrary to popular belief, the eyes are not perfectly spherical; instead, it is made up of two separate segments fused together. To understand more in detail about our eye and how our eye functions, we need to look into the structure of the human eye.

What Is Spherical Aberration ? Why To Use Aspheric Lens ?
Переглядів 1 тис.Рік тому
This video explains the basic concept of spherical aberration and its solution as Aspheric lenses. What is a spherical aberration? It is a phenomenon in which the outer parts of a lens do not bring light rays into the same focus as the central part. Rays passing through the lens close to its centre are focused farther away than rays passing through a circular zone near its rim. This occurs beca...

Contact Lens Types I Difference Between Corneal , Corneoscleral & Scleral Lenses
Переглядів 9834 роки тому
Contact lenses are artificial devices applied on the eye's front surface to substitute for the anterior corneal surface. They help correct the cornea's refractive error, irregularities, and surface abnormalities. The idea of contact lenses was first proposed in 1508 by Leonardo da Vinci, who gave birth to the concept of neutralization of the cornea by a new refracting surface. In 1946, contact ...

That's right 👍 Thanks for commenting Rimi!

What if the vision loss is sudden ??
Hi Rakhi! There's a list of eye conditions which can have a sudden vision loss. Common causes could be eye injury, retinal artery/ vein occlusion. Most importantly this should be confirmed by a detailed eye examination at an eye care centre.
Interesting !
I think so too!
Good one !
Thank you! Cheers!
Sir Which book you use for opthalmology??
Dear Rahim! I read Comprehensive Ophthalmology by A K Khurana to learn Ocular Anatomy. I also enjoy reading Kanski's Clinical Ophthalmology.
Explained clearly ♥️. Good job
Thanks for appreciating. Glad it helped!
Great Video
Thank you Gargi ❤
Much worthy diagram and well explained
Thank you Nidhish.
Great explanation
Glad you liked it. Thank you for appreciating.
Thank you sir, it's very informative
Sir i have sudden vision loss for less then second.please tell me what happened?
Hi Mihiranga. Transient vision loss for a second or less may not be clinically significant. But it would be advisable for you to go for a detailed eye examination by an Optometrist /Ophthalmologist at a nearby Eye Hospital to rule out any eye condition. Take care!
Hi Sir, DIMNESS (improved now 90%), LONG DISTANCE MILD CLARITY LOSS, FLOATERS, GHOSTING IMAGES OF ROUND LIGHT SOURCES AND SHADOW OF TEXT on TV.. RETINA GOOD, VISUAL FIELD TEST GOOD Explaination: I had dim vision for 10 days. It's like transaparent black small dots collected together to form a shadow effect, in short very dull vision, so lights were not enough how much ever bright we put. Then fixed placed floaters appeared around 12 not annoying to vision, some small black some transparent. Ever since 1st day, I had LONG DISTANCE clarity loss.. notice it on buildings which were once super crisp and clear. Now there is some air like thing I notice on the building and smoothning its surface causing little loss of clarity. My blood vessels were so popped up in my eyes too..but not a red eye..just vessels bulged..what could I have suffered??
@@roopaofficial5633Hi Roopa ! Just visit a nearby eye care center. If you have already visited & everything is with in normal limits then just relax. Get well soon.
This is very well done. I like how you are able to put the information into context so it makes sense why things are named the way they are and what the big picture is as well as the details. Thank you very much
Thank you so much for appreciating 😊

Very useful sir👍

Hi sir, wanted to know that the height 4mm above the pupillary centre is for regular Executive bifocals or PAL or progressive lenses (myopia control). Also what is the preferred near add for prescription of bifocals for myopia control of 7 yr old with 3D myopia?
Hi. In case of kids with convergence excess accommodative esotropia while dispensing executive bifocals, the segment height should be at the pupillary center. For the same patient if you plan to dispense a progressive lens, fitting cross height should be 4mm higher than the pupillary center. However the preferred option would be to dispense an executive bifocal.
Also, most PAL studies for myopia control have used +1.50 or + 2.00 Add. However in practice, individualising the add depending on the binocular vision status (phoria, accommodative lag) & visual comfort is critical. Thank you 😊
