Understanding Monovision: The Pros and Cons for Your Vision Care Needs

Monovision is a technique used in the field of optometry, that involves correcting one eye to focus for distance vision, and the other eye to focus for near vision. This can be achieved through the use of contact lenses, glasses or refractive surgery.

Many people over the age of 40 experience presbyopia, which is a natural age-related loss of near vision. Monovision can be a viable option for those who do not want to rely solely on reading glasses or bifocals.

The Process

During a monovision consultation, an optometrist will check the health of your eyes and assess your suitability for the procedure. Patients will typically try contact lenses of varying prescriptions to find the combination that provides the best balance for their individual visual needs.

Once a patient has determined their ideal prescription, they can opt for either contact lenses, glasses, or refractive surgery to achieve monovision. The chosen method will depend on factors such as personal preference, lifestyle and overall eye health.

The Pros and Cons

One of the main benefits of monovision is convenience. The patient only needs one pair of glasses, or in the case of contact lenses, one prescription for both distance and near vision. This can save time, money and hassle compared to having separate glasses or lenses for different tasks.

However, some patients may struggle to adapt to the difference in prescription between their eyes. It can take several weeks or even months for the brain to adjust and process the visual information correctly. Additionally, while reading may become easier, distance vision may suffer slightly in the eye corrected for near vision.

The Verdict

Monovision can be a suitable option for those who wish to reduce their reliance on reading glasses or bifocals. However, it is important to consider the potential drawbacks, such as the adjustment period and slight compromise in distance vision. Consulting with an optometrist can help determine if monovision is the right choice for you.


Overall, monovision can be an effective solution for those experiencing presbyopia. It offers convenience and eliminates the need for multiple prescriptions. The decision to proceed should be made on an individual basis, as not everyone will find it suitable for their needs.

  • Pros – Convenience, cost-effective
  • Cons – Adaptation period, slight reduction in distance vision
