Understanding Refractive Errors: Myopia, Hyperopia, and Astigmatism

At Enny Eye Care, we believe that clear vision is essential for a healthy and fulfilling life. Refractive errors, one of the most common vision problems, occur when the shape of your eye prevents light from focusing correctly on the retina. Let’s break down the three most common refractive errors—myopia, hyperopia, and astigmatism—and explore how they affect your vision.

1. Myopia (Nearsightedness)

Myopia, commonly known as nearsightedness, occurs when the eyeball is too long or the cornea is too curved. This causes light to focus in front of the retina instead of directly on it, making distant objects appear blurry.

Symptoms: People with myopia can see nearby objects clearly, but distant objects may appear fuzzy or out of focus.
Causes: Myopia is often hereditary and can develop during childhood. Prolonged near tasks, such as reading or screen time, may also contribute to its progression.
Treatment: Myopia can be corrected with prescription glasses, contact lenses, or refractive surgery (such as LASIK) to reshape the cornea.

2. Hyperopia (Farsightedness)

Hyperopia, or farsightedness, occurs when the eyeball is too short or the cornea is too flat. This causes light to focus behind the retina, making nearby objects blurry while distant objects remain clear.

Symptoms: Individuals with hyperopia may have difficulty focusing on objects up close, especially when reading or doing detailed work.
Causes: Like myopia, hyperopia is often genetic. Many people are born with some degree of hyperopia, which may decrease as the eye grows and develops.
Treatment: Prescription glasses or contact lenses can correct hyperopia by focusing light properly on the retina. Refractive surgery is also an option for those seeking a more permanent solution.

3. Astigmatism

Astigmatism is a condition where the cornea or lens is irregularly shaped, causing light to focus unevenly on the retina. This results in blurred or distorted vision at all distances.

Symptoms: Astigmatism can cause blurry or wavy vision, headaches, and eye strain. Many people with astigmatism also have myopia or hyperopia.
Causes: Astigmatism can be present at birth or develop over time. It often occurs in combination with other refractive errors.
Treatment: Astigmatism can be corrected with glasses, contact lenses, or specialized lenses known as toric lenses. In some cases, refractive surgery may be recommended.
