Myopia and hypermetropia are two common refractive eye conditions that affect a person's ability to see clearly at various distances. They are often referred to as nearsightedness and farsightedness, respectively.

Myopia (Nearsightedness):
Myopia is a refractive error in which a person can see objects clearly up close but has difficulty seeing distant objects clearly. It occurs when the eyeball is too long or the cornea (the clear front surface of the eye) is too steeply curved, causing light entering the eye to focus in front of the retina instead of directly on it.
As a result, distant objects appear blurry while close objects can be seen clearly. Myopia can develop during childhood and often progresses over time, especially in teenagers. It is commonly corrected with eyeglasses or contact lenses that have a concave (minus) lens prescription to help shift the focus of light back onto the retina.

Hypermetropia (Farsightedness):
Hypermetropia is a refractive error in which a person can see distant objects more clearly than nearby objects. It occurs when the eyeball is too short or the cornea is too flat, causing light to focus behind the retina instead of directly on it.
People with hypermetropia may experience blurred vision when looking at things up close, and they may have difficulty with tasks like reading or using a computer without correction. Hypermetropia can affect individuals of all ages and may be more noticeable as they age due to changes in the eye's lens elasticity. It is usually corrected with eyeglasses or contact lenses that have a convex (plus) lens prescription to bring the focal point of light forward onto the retina.

Both myopia and hypermetropia are common vision problems and can often be easily corrected with the appropriate eyeglasses or contact lenses.
