Explanation:
•Myopia and Hypermetropia?
Both Myopia (short-sightedness) and Hypermetropia (long-sightedness) are common eye conditions that are occur when light does not focus on the retina of the eye. Both conditions are easily corrected using prescription glasses or contact lenses or in mild cases by laser eye surgery.
•MYOPIA
Myopia affects nearly 30 percent of the U.S. population. Myopia is the term used to define short sightedness. Light from a distant object forms an image before it reaches the retina. This could be because the eye is too long, or the cornea or crystalline lens is too strong.
•HYPERMETROPIA
Hypermetropia (Hyperopia) means long sight and is where the image of a nearby object is formed behind the retina. This could be because the eye is too short, or the cornea or crystalline lens does not refract the light enough.
•What Are the Symptoms and Causes?
A myopic person has clear vision when looking at objects close to them, but distant objects will appear blurred. While the exact cause of myopia is unknown, research suggests that the condition is inherited. If one or both parents are nearsighted, there is a great likelihood their children will be nearsighted. Evidence also suggests that the condition may stem from how the individual uses her eyes. Hobbies or employment that requires regular and intense close-up use of your eyes (reading, logging daily hours behind the computer) can increase your odds of developing myopia. The conditions have also been linked to environmental factors and health problems.
A hypermetropic person may have blurred vision when looking at objects close to them, and clearer vision when looking at objects in the distance. In the young, because of the reserve capacity of the eye, there are often little, or no symptoms of the condition. As you age, common symptoms are headaches and eye strain. You may also have difficulty with focusing on objects up close. Red eyes from the strain is also a visual symptom. Sometimes the eye will feel dry and ache. After the age of 38, it is very common for the eyes to not be able to focus appropriately on images close to the eyes. Reading material is often held at an arm’s length to be seen.
•What Are the Treatment Options?
Myopia and hypermetropia are both easily corrected at Optical Masters using prescription glasses or contact lenses specifically designed to counteract the effect. For myopia, a concave lens (minus powered) is placed in front of a myopic eye, moving the image back to the retina and clarifying the image. For some patients, contact lenses provide clearer vision and a wider field of view than eyeglasses. For patients with hypermetropia, you will be prescribed with eyeglasses or contacts that place a convex (plus powered) lens in front of a hypermetropic eye, allowing the image to move forward and focus correctly on the retina. Keep in mind that contact lenses are worn directly on the eyes and, thus, necessitate adhering to proper care and health standards to safeguard eye health. You can work with your eye doctor at Optical Masters to determine which method will work best for your individual circumstances and abilities.

Pls MARK IT AS BRAINLIEST
♀ A person suffering from this defect can see nearby objects clearly but distant objects apear blurred. The ciliary muscles do not relax sufficiently to make the eye lens thin when viewing distant objects. As a result, the image of a distant object is formed before the retina and cannot be clearly seen.
♀ Hypermetropia : A person suffering from this defect can see distant objects clearly but nearby objects appear blurred. The ciliary muscles are unable to thicken the eye lens enough to see nearby objects clearly. This defect generally occurs in old age when the ciliary muscles become in old age when the ciliary muscles become weak.
