Hyperopia

Commonly known as long-sightedness, this is a frequent vision concern where individuals typically find near vision more of a struggle than seeing objects in the distance. However, as our clinical team at Acuity Eyecare often explains, the condition is not always that simple. Depending on your age and the degree of the prescription, hyperopia can affect your visual comfort in various ways throughout the day.

What is Hyperopia?

Hyperopia is a refractive error that occurs when light entering the eye does not focus directly on the retina at the back of the eye. Instead, the focal point falls behind the retina. This usually happens because the eyeball is slightly shorter than average or the cornea lacks sufficient curvature.

When we are younger, our eyes generally possess a significant amount of "flexible" focusing power, known as accommodation. This allows the internal lens to work harder to pull that image forward onto the retina, often providing clear distance vision despite the underlying hyperopia.

However, this constant "internal workout" can come at a cost. After a long day of the visual system overworking to maintain clarity, the eyes can become tired and fatigued. This often leads to blurry near vision, headaches, or a heavy sensation around the brows. It is very similar to a gym workout; if you use the same muscles repeatedly without rest, they eventually fatigue to a stage where they no longer function at an optimal level.

Risks of Uncorrected Hyperopia

In cases where there is a high degree of hyperopia, the eye's natural focusing power may not be enough to compensate for the blur. When the visual system is forced to over-accommodate just to see clearly, it can lead to significant developmental complications, particularly in children. Early detection at Acuity Eyecare is vital to ensure the following conditions do not impact a child's visual milestones:

Accommodative Esotropia (turned eye)

This specific type of turned eye occurs because the effort required to focus the long-sighted eye is so intense that it triggers a "crossing" reflex. This causes one eye to drift inwards toward the nose as the brain tries to clear the image.

Correcting the underlying hyperopia with prescription glasses is often the primary way we realign the eyes and relieve this internal strain.

Amblyopia
(lazy eye)

If the brain receives a significantly clearer image from one eye than the other, or if a turned eye is present, it may begin to favour the stronger eye to avoid confusion. This leads to a lazy eye, where the neurological connection to the weaker eye fails to develop fully.

If not caught during a comprehensive eye exam in early childhood, this can result in permanent vision loss that cannot be corrected by glasses alone in adulthood.

Treatment & Management

If you find yourself straining at the end of the day or notice your near vision becoming increasingly blurred, it may be time to assess your level of hyperopia. The good news is that hyperopia is a manageable refractive error. Most patients find excellent relief and clarity through a tailored pair of prescription glasses or contact lenses.

At Acuity Eyecare, we also offer specialised contact lens options such as Ortho-K (orthokeratology). This involves the use of custom-designed lenses worn overnight to gently and temporarily reshape the cornea. While often associated with myopia, Ortho-K can also be used to correct hyperopia and astigmatism, providing clear vision during the day without the need for frames or traditional daytime contacts.
