**Core Concept**
Presbyopia is a age-related decline in near vision, typically beginning in the early to mid-40s. It is caused by a decrease in the flexibility of the lens inside the eye, making it difficult for the lens to focus on close objects. The affected individual often experiences difficulty with near vision tasks, such as reading or using digital devices.
**Why the Correct Answer is Right**
The treatment of presbyopia involves the use of a lens that can compensate for the decreased flexibility of the natural lens. This is typically achieved with a **plus lens**, also known as a converging lens, which converges light and allows for near vision. The correct answer is **Converging Lens**, as it is the type of lens used to treat presbyopia by providing additional focusing power.
**Why Each Wrong Option is Incorrect**
**Option A:** Myopic lens - This type of lens is used to correct nearsightedness, not presbyopia, as it diverges light and reduces focusing power.
**Option B:** Aspheric lens - While aspheric lenses are used in various ophthalmic applications, they are not specifically used to treat presbyopia.
**Option C:** Toric lens - Toric lenses are used to correct astigmatism, a condition where the cornea or lens is irregularly shaped, not presbyopia.
**Clinical Pearl / High-Yield Fact**
A converging lens is used to treat presbyopia by providing additional focusing power, allowing the individual to see near objects clearly. This can be achieved with glasses, contact lenses, or refractive surgery.
**Correct Answer:** C. Converging Lens.
