Take This Quiz To Know The Symptoms Of Myopia!

Explanation
Myopia, also known as nearsightedness, is a refractive error of the eye where distant objects appear blurry. It is caused by the elongation of the eyeball or steepening of the cornea, resulting in light rays focusing in front of the retina instead of directly on it. While myopia itself does not directly cause complications such as blindness, it can increase the risk of developing certain eye conditions, including cataracts. Cataracts occur when the lens of the eye becomes cloudy, leading to blurred vision and potentially vision loss if left untreated. Therefore, cataract is the complication that can result from myopia.

Explanation
Myopia, also known as nearsightedness, is a refractive error that causes distant objects to appear blurry. It is a hereditary defect, meaning it is passed down from parents to their children through genes. This means that if one or both parents have myopia, there is a higher chance of their children also developing the condition. This defect occurs when the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina instead of directly on it. This results in difficulty seeing objects in the distance clearly.

Explanation
When an image is sighted from closed objects, it appears blurred. This is because the light rays coming from different points on the object do not converge to form a clear image on the retina. Instead, they spread out, resulting in a blurred image.

Explanation
Smoking is not a cause of myopia. Myopia, also known as nearsightedness, is primarily caused by factors such as near work (such as reading or using electronic devices at a close distance), spending excessive time indoors, and heredity. However, smoking does not contribute to the development of myopia.

Explanation
The odd cause among the given options is "Injection" because it is the only cause that does not directly relate to vision correction or eye health. Surgery, contact lenses, and eyeglasses are all commonly associated with addressing vision issues, while injections are typically used for medical treatments unrelated to vision correction.

Explanation
Myopia, also known as nearsightedness, is a condition in which a person can see nearby objects clearly, but distant objects appear blurry. The retina is the part of the eye that is responsible for capturing light and sending visual signals to the brain. In the case of myopia, the eyeball is slightly elongated, causing the light to focus in front of the retina instead of directly on it. This results in a blurred image when looking at distant objects. Therefore, the retina is the part of the eye that is affected before the outbreak of myopia.

Explanation
Catarrh is not a symptom of myopia. Myopia, also known as nearsightedness, is a condition where close objects appear clear while distant objects appear blurry. Symptoms of myopia typically include headaches, eye strain, and blurry vision when looking at close objects. Catarrh, on the other hand, refers to inflammation of the mucous membranes in the nose and throat, and is not related to myopia.

Explanation
The given question asks to identify the odd term out of the options provided. All the options, except for "Farsightedness", refer to the same eye condition, which is the inability to see objects clearly unless they are relatively close to the eyes. However, "Farsightedness" refers to the opposite condition, where distant objects are seen more clearly than nearby objects. Therefore, "Farsightedness" is the odd term out as it represents a different eye condition compared to the other options.

Explanation
Spending much time indoors is a common cause for children. This is because when children spend most of their time indoors, they have limited exposure to sunlight and fresh air, which can lead to various health issues. Lack of outdoor activities and exercise can also contribute to a sedentary lifestyle, obesity, and weakened immune system. Additionally, spending excessive time indoors may also limit social interactions and opportunities for cognitive development.

Explanation
Myopia is the correct answer because it is commonly known as shortsightedness. Myopia is a condition of the eye where distant objects appear blurry, while close objects can be seen clearly. This occurs when the eyeball is slightly longer than usual or when the cornea is too curved, causing the light entering the eye to focus in front of the retina instead of directly on it.
