What is Hypermetropia Bilateral?


Hypermetropia, commonly known as farsightedness, is a refractive error in which distant objects can be seen more clearly than near ones. The term “bilateral” signifies the condition’s presence in both eyes. This article unravels the intricacies of bilateral hypermetropia, its causes, symptoms, and the potential treatment options available.

The Science Behind Hypermetropia

In a normal eye, light entering the eye is focused precisely on the retina, producing a sharp image. However, in hypermetropia, the eye is either too short or the cornea has too little curvature. As a result, light rays focus behind the retina, making close objects appear blurry.

There are two primary types of hypermetropia:

  1. Axial Hypermetropia: Occurs when the eyeball is too short from front to back.
  2. Curvature Hypermetropia: Arises due to an abnormal curvature of the lens or cornea.

Bilateral Hypermetropia – A Dual Concern

When hypermetropia affects both eyes, it is termed as “bilateral.” This means that both eyes struggle with near vision. This condition is not uncommon, as refractive errors often manifest similarly in both eyes. However, the degree of hypermetropia might vary between the two eyes, leading to one eye being more farsighted than the other.

Symptoms often include:

  • Blurred vision for close objects
  • Eye strain or discomfort after prolonged close-up tasks
  • Headaches after tasks like reading or computer work
  • Needing to squint to see clearly
  • Crossed eyes in children

Causes and Risk Factors

Bilateral hypermetropia can arise due to several reasons:

  1. Genetics: A strong familial link often exists. If parents have hypermetropia, their children are more likely to inherit the condition.
  2. Age: As one ages, the eye’s lens becomes less elastic, decreasing its ability to focus on close objects, leading to age-induced hypermetropia.
  3. Medical Conditions: Some diseases, like diabetes, can affect the eye’s refractive abilities.
  4. Medications: Certain drugs can alter the eye’s shape or its ability to refract light.

Treatment Options

Addressing bilateral hypermetropia ensures improved vision and quality of life. Under the expert guidance of professionals like Dr. Rajesh Khanna MD at Khanna Vision Institute, several treatment avenues are available:

  1. Corrective Lenses: The most common solution, glasses or contact lenses, can correct the refractive error, providing clear near vision. The lenses have a converging effect, redirecting light rays onto the retina.
  2. Refractive Surgery: Procedures like LASIK or PRK reshape the cornea’s curvature, providing a more permanent solution. The choice of surgery depends on individual cases and the specific anatomy of the eye.
  3. Intraocular Lenses (IOLs): For those who may not be candidates for LASIK or PRK, or for age-related hypermetropia, implantable lenses might be an option.

Living with Bilateral Hypermetropia

Managing bilateral hypermetropia involves regular eye check-ups to monitor the condition’s progression, especially as one ages. Adapting to lifestyle changes, such as using appropriate lighting for reading or ensuring frequent breaks during close-up work, can alleviate symptoms. Early detection in children is particularly crucial to prevent complications like lazy eye.


Bilateral hypermetropia, while challenging, is a manageable condition. With advancements in ophthalmic care and the dedicated efforts of experts like Dr. Rajesh Khanna MD, individuals can navigate this refractive error with ease, ensuring optimal vision and a high quality of life.
