Common Problems affecting Sight: 1. Myopia/nearsightedness:
Myopia, also known as nearsightedness, is a common type of refractive error where close objects appear clearly, but distant objects appear blurry. Myopia develops in eyes that focus images in front of the retina instead of on the retina, which results in blurred vision. This occurs when the eyeball becomes too long and prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens. Myopia can affect both children and adults.
Some of the signs and symptoms of myopia include: * Headaches * Eyestrain * Squinting * Difficulty seeing distant objects, such as highway signs
Myopia can be corrected with eyeglasses and contact lenses and surgery.

2. Hyperopia/farsightedness:
Hyperopia, also known as farsightedness, is a common type of refractive error where distant objects may be seen more clearly than objects that are near. Hyperopia develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision. This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens. Hyperopia can affect both children and adults.

The symptoms of hyperopia vary from person to person.
But some common signs and symptoms of hyperopia are very similar to Myopia which are: * Headaches * Eyestrain * Squinting * Blurry vision, especially for close objects

3. Astigmatism:
Astigmatism is a common type of refractive error. It is a condition in which the eye does not focus light evenly onto the retina, the light-sensitive tissue at the back of the eye. Astigmatism occurs when light is bent differently depending on where it strikes the cornea and passes through the
