Nearsightedness may develop gradually or rapidly, often worsening during childhood and adolscence. Nearsightedness tends to run in famillies. A basic eye exam can confirm if your nearsighted. you can easily correct the condition with eye glasses or contact lenses. Another treatment option for Myopia is surgery. The underlying cause is believed to be a combination

I’ve had severe myopia (nearsightedness) and astigmatism all my life, but I didn’t know it until midway through 2nd grade. I have roughly 20/400 uncorrected vision, meaning that at 20 feet away words have to be 20 times bigger. Without glasses, pretty much everything that isn’t within 10” of my face is out of focus. However, I didn’t notice that anything was wrong with me until the 1st grade, when I could barely read the board from the front of the room when everyone else was fine. In 2nd grade,

INTRODUCTION Myopia is the refractive anomaly of the eye in which close objects appears clearly, while objects far away appear blurry. With myopia, light comes to focus in front of the retina instead of on the retina Myopia is the major refractive error having a worldwide prevalence of 1.5 billion. Children with Myopia feel difficulties in viewing blackboard in school; they avoid outdoor activities and get isolated from the peer groups. Untreated myopia may lead to Macular degeneration, Glaucoma

Introduction According to the dictionary, a sensation is the operation or function of the senses; perception or awareness of stimuli through the senses, while a perception is the act or faculty of perceiving, or apprehending by means of thesenses or of the mind; cognition; understanding. The eye is defined as white membrane that contains an opening for light to get to the retina. The eye is developed in a way that it receives physical stimuli like light and send it to the brain as an electrical

Blog Blue Moon Optical The eyes perform the crucial function of capturing images; these images are then sent to the brain for interpretation. The eyes need to bend the light rays to allow the retina to apply focus for the whole process to complete. People, who have vision problems, often suffer from refractive or light bending problems. The solution to most refractive problems is wearing contact lenses or glasses. The other common interventions for eye problems include; vision therapy, ortho-k procedure

eye defects Myopia, Glaucoma and Cataracts. What is Myopia? Myopia is a defect within the eye that causes near-sightedness or short-sightedness.

Normally when you look at an object, the object is being focus right on the retina, but someone having Myopia, when looking

At birth, infants were found to be somewhat hyperopic. As they grow older and begin emmetropization, a portion of children begin to acquire myopia. The amount of children with myopia increases from 2% at age 6 to 20% or greater at age 20. 1 The prevalence of myopia reaches a peak of 30% between age 20 and 40. 1 After the adult years, it is believed that there is minimal change in refractive error. However, due to nuclear lens changes, approximately 10%
