𝐅𝐚𝐬𝐜𝐢𝐧𝐚𝐭𝐢𝐧𝐠 𝐅𝐚𝐜𝐭𝐬 𝐀𝐛𝐨𝐮𝐭 𝐄𝐲𝐞 𝐀𝐧𝐚𝐭𝐨𝐦𝐲 𝐚𝐧𝐝 𝐕𝐢𝐬𝐢𝐨𝐧! Refractive power of the eye: About 60 diopters (cornea about 40 diopters, lens: about 20 diopters) On the retina of an eye there are more than 100 million sensory cells sending the image information to the brain (a camera has probably 10 million pixels). The retina contains two types of photoreceptors, rods and cones. The rods are with some 120 million more numerous. They are responsible for seeing at night. The 6 to 7 million cones provide the eye‘s colour sensitivity for seeing at daylight. They are concentrated in the 0.3 mm diameter fovea. The eye can be very strong: In a dark night, you can see the light of a candle in up to 25 km distance! #EyeAnatomy #VisionScience #Optometry #EyeHealth #RefractivePower #SensoryCells #Photoreceptors #VisionCare #Healthcare #LightAndVision #OpticalScience #GEMOPTICIANS

Did you know that myopia, or nearsightedness, is becoming more common in children? Myopia is a condition where distant objects appear blurry while close objects are clear. This happens when the eye’s shape causes light to focus in front of the retina instead of on it. Myopia not only directly impairs vision but also increases the risk of cataracts and glaucoma. Learn more about the causes and risks of myopia and how it can affect your child’s vision. https://bit.ly/3zejpbm. Experience the #Myopia Simulator courtesy of Hoya Vision Care at https://bit.ly/4gFuAKM #accessibility Image description: The image is an educational diagram comparing a normal eye with a myopic (nearsighted) eye. Normal Eye: Shows light rays focusing directly on the retina, resulting in clear vision.

Not-so-Cold Plunge Musings: #1 (Why not?) How much of what we believe is based on what we can see? (Think about it if you dare!) After being horizontal, face down, with my eyes on the floor from Wednesday after my surgery until Sunday morning, my eye surgeon released me to be able to be upright and even go for a walk—FREEDOM! One of the ways I celebrated this newfound indulgence was to walk to the edge of a lake where I was, sit down on a bench in the shade, and quietly enjoy being outside. As the birds sang up a storm, my Cornell University app identified twelve birds. Two included a Canadian Goose and a Mallard duck that happened to be swimming towards me. As they got right in front of me, I closed my right eye to see what I could discern with my left eye (the one that had the detached retina). While I could see colors and shapes in my left eye, both the goose and duck vanished. (The doctor inserted silicone oil in that eye to help stabilize the retina, so I’ll be looking through this oil for the next few months until they remove the oil via another vitrectomy surgery.) At that moment, it hit me… “Just because we can’t see it doesn’t mean it isn’t there.” Think about it. Before we had the Hubble Telescope (followed by the mind-boggling Webb Telescope), we couldn’t fathom some things in the Universe because we’d never seen them. The same is true on the microscopic level. Before we had high-power microscopes, we had no clue about atomic particles. These things have been there LONG before humanity believed they could be there. Just because we can’t see it doesn’t mean it’s not there. There’s more to the matter than what we can see.

An artificial intraocular lens (IOL) is primarily required for people with cataracts, a condition where the eye's natural lens becomes cloudy, obscuring vision. They can also be also used to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness) and presbyopia (when eyes gradually lose the ability to see things clearly up close, as a normal part of aging). #vision #optometry 360care.com LEARN MORE: https://lnkd.in/gvcEEMnC

Understanding Common Vision Issues 👁️📖 Vision problems can manifest in different ways, each affecting how we see the world. Here’s a quick guide to four common conditions: 1. Double Vision: This occurs when you see two images of a single object. It may be caused by issues with eye alignment, nerve damage, or lens problems. 2. Astigmatism: Blurred or distorted vision due to an irregularly shaped cornea or lens. This makes it hard to see details clearly at all distances. 3. Poor Focusing (Accommodation): Difficulty focusing on objects up close or far away, common as we age. This can make it hard to switch focus between near and far objects. 4. Eye Movement Problems: When eye muscles don’t work in sync, it can cause jerky or misaligned vision. This affects how the eyes track moving objects or align images from each eye. Each condition impacts daily life differently, but the good news is that most can be managed with proper diagnosis and treatment. Regular eye exams are essential to detect these issues early and maintain clear, comfortable vision! #VisionAwareness #EyeHealth #Astigmatism #DoubleVision #EyeCare #NeelamEyeHospital #EyeExams #Optometry

👓 Understanding Vision: Your eye shape plays a key role in how you see: 🔹 Nearsightedness (Myopia): The eye is longer, causing distant objects to appear blurry. 🔹 Normal Vision: Light focuses perfectly on the retina for clear sight. 🔹 Farsightedness (Hyperopia): The eye is shorter, making near objects blurry. Regular eye exams can help detect and correct these refractive errors. Protect your vision! ✨ #EyeCare #Nearsightedness #Farsightedness #HealthyVision

#Age_Related_Macular_Degeneration (AMD): 🔸Age-Related Macular Degeneration (AMD) is a common eye condition that affects individuals over 50, leading to the progressive loss of central vision. 🔸This vision loss occurs due to damage to the macula, the central part of the retina responsible for sharp, detailed vision. 🔸While AMD doesn't cause complete blindness, it significantly impacts daily activities like reading, driving, and recognizing faces. Early detection through regular eye exams is crucial, as treatments can slow progression and preserve vision for longer. ❓Why do you think telescopes might not be suitable for individuals with Age-Related Macular Degeneration, considering it primarily affects central vision? Share your insights!

# EYE The eye is a complex organ that plays a crucial role in vision. It consists of several parts: 1. Cornea: The clear front layer that helps focus light. 2. Lens: Adjusts shape to focus light onto the retina. 3. Retina: Contains photoreceptor cells (rods and cones) that convert light into electrical signals. 4. Optic Nerve: Transmits visual information from the retina to the brain. Vision Process: Light enters through the cornea, passes through the lens, and is focused on the retina. The retina processes this light and sends signals to the brain, where they are interpreted as images. Common Vision Issues: Myopia (nearsightedness): Difficulty seeing distant objects. Hyperopia (farsightedness): Difficulty seeing close objects. Astigmatism: Distorted vision due to an irregularly shaped cornea or lens. Presbyopia: Age-related difficulty in focusing on close objects. Eye Health: Regular eye exams are important for maintaining eye health and catching issues early. Protecting eyes from UV light, managing screen time, and maintaining a healthy diet can also support good eyesight.

The #AmesRoom, designed by ophthalmologist Adelbert Ames Jr. in 1946, is a perfect example of how perception can be manipulated. 🧠 By using a trapezoidal shape, this optical illusion fools our brains into thinking the room is a regular rectangle. It’s a fascinating reminder of how easily our minds can be tricked by clever design! 😲✨ Curious to experience the magic of perception? 🤔 #OpticalIllusion #BrainTricks #AmesRoom #InnovativeDesign #MindBlown #LearnThroughIllusion #PerceptionIsReality #ty #tyt #tytly #tytlyinfotech
