What Is Minus and Plus of Power in Your Eye?
Understanding the Impacts on Your Vision

When you visit an optometrist, you might hear terms like "minus power" and "plus power" in reference to your prescription. These terms are used to describe the type of vision correction you need to see clearly. In this article, we’ll break down what these terms mean, how they affect your vision, and what options are available for correction. Whether you’re struggling with nearsightedness or farsightedness, we’ll help you understand how these different powers affect your life.

What Does Minus Power in Your Eye Mean?

Minus power, commonly associated with myopia (nearsightedness), refers to the type of lens prescribed to correct your vision when you struggle to see objects clearly at a distance. If your prescription contains a minus sign (e.g., -2.00), it means you're nearsighted.

Symptoms and Causes of Minus Power

People with minus power may find it difficult to see distant objects clearly, while objects up close may appear perfectly fine. This condition typically occurs when the eyeball is too long or the cornea has too much curvature. Genetics, environmental factors, and prolonged screen time can contribute to its development.

The Impact of Minus Power on Your Vision

Living with myopia means you might squint at far-away objects or avoid activities that require good distance vision, like driving. The severity of your minus power can vary from mild to severe, but even a small amount of myopia can impact your quality of life.

What Does Plus Power in Your Eye Mean?

On the flip side, plus power is used to correct farsightedness, also known as hyperopia. If your prescription has a plus sign (e.g., +1.50), it indicates that you have difficulty focusing on nearby objects.

Symptoms and Causes of Plus Power

Those with hyperopia may notice eye strain when reading, working on a computer, or engaging in any task that requires near vision. Plus power occurs when the eyeball is too short, causing light entering the eye to focus behind the retina rather than directly on it.

The Impact of Plus Power on Your Vision

Individuals with plus power often experience blurry vision when viewing close-up objects, and they may feel the need to squint. Over time, hyperopia can lead to eye fatigue and headaches, especially if the condition worsens and goes untreated.

Minus Power vs Plus Power: Key Differences

Though both conditions relate to the inability to focus clearly, they are polar opposites. Minus power helps with seeing far away, while plus power assists with near vision. Age also plays a role, as hyperopia often develops later in life, while myopia typically appears in childhood.

How Is Your Eye Prescription Determined?

Optometrists assess your vision through eye tests like the Snellen chart or retinoscopy. Based on the results, they’ll write a prescription that includes measurements for both the strength of the lens needed (in diopters) and the type of vision correction required, whether it’s plus or minus power.

Can Minus and Plus Powers Be Corrected?

Both minus and plus powers can be corrected with various solutions. Eyeglasses and contact lenses are the most common methods. In more advanced cases, surgery such as LASIK or PRK might be an option for those seeking a permanent solution.

Understanding the Role of Astigmatism in Power Measurements

In some cases, individuals with plus or minus power may also have astigmatism, which occurs when the cornea is not evenly shaped. This can further complicate the vision correction process, requiring a more complex prescription.

When Should You Seek Treatment for Eye Power Imbalances?

If you’re experiencing blurry vision, frequent headaches, or difficulty focusing, it’s time to see an eye care professional. At Dr. SKS Memorial Eye Hospital, our experts can assess your condition and provide the best treatment options tailored to your needs.

How to Maintain Healthy Eyesight with Minus or Plus Power

Prevent eye strain by taking breaks when working on screens, wearing proper eyewear, and eating a nutrient-rich diet with foods like leafy greens, carrots, and fish. Regular exercise can also improve circulation to the eyes.

The Future of Vision Correction: What’s Next?

With advancements in medical technology, the future of vision correction is promising. From gene therapy to sophisticated laser surgeries, new treatments are being developed to offer more precise and long-lasting solutions to vision issues.
