Understanding the Symptoms of High Myopia and Hyperopia

High myopia, also known as hyperopia, is a common refractive error of the eye. While myopia affects the ability to see nearby objects clearly, hyperopia affects the ability to see distant objects without effort. This article delves into the symptoms of hyperopia, as discussed by Ben R. Wilkinson, FRCSC, providing valuable insights for those seeking a better understanding of this condition.

What is Hyperopia?

Hyperopia, or farsightedness, occurs when an eyeball is optically too short, leading to an image in the distance being focused behind the retina, causing the image to appear blurry. This can happen if the length of the eyeball is too short or if the cornea is too curved or the eye lens is too strong.

Causes and Development

Babies are often born with small eyeballs, leading to initial hyperopia. However, their eyes grow quickly, and they can correct this by adolescence. In adults, hyperopia means more effort is needed to focus on distant objects, and even more is required to focus on nearby objects. This often necessitates the use of reading glasses at a younger age than the general population, commonly in their late 40s. Over time, most hyperopic individuals will require glasses for both near and distance vision and may eventually need bifocal lenses.

Visual Symptoms of Hyperopia

Common visual symptoms of hyperopia may include:

Blurred Near Vision: It can be difficult for hyperopic individuals to see objects up close, such as when reading or using a computer. Clear Distant Vision: In contrast, distant objects are generally seen more clearly without correction.

Other symptoms include:

Blurry Vision: Nearby objects may appear blurry, especially during activities that require close focus like reading or detailed work. Eye Strain: Extended periods of focusing on close objects can lead to eye strain and discomfort. Headaches: Straining the eyes to focus on nearby objects can cause headaches. Difficulty Reading: Especially with small print or detailed tasks requiring close focus. Squinting: Hyperopic individuals may squint to improve focus. Eye Fatigue: Tiredness or discomfort in the eyes after short periods of reading or close work.

Addressing Hyperopia

Correcting hyperopia involves the use of eyeglasses or contact lenses. Convex lenses are typically prescribed to help bring light to a proper focus on the retina, correcting the optical error that causes the image to appear blurry.

Treatment Options and Considerations

For children with hyperopia, Visual Therapies such as the use of corrective glasses can be essential. In some cases, patching can be used to treat lazy eye and improve visual function. Immediate treatment of a lazy eye is crucial to prevent permanent vision loss.

Conclusion

Understanding the symptoms of hyperopia can help individuals recognize when their vision is affected and seek appropriate correction. Early intervention is key to maintaining clear vision and preventing complications. For more information about hyperopia and available treatment options, consult an eye care professional.
