What is the recommended diameter range for soft contact lenses?

The recommended diameter range for soft contact lenses typically falls between 12.0 mm to 14.5 mm. This range is optimal for achieving the right fit on the cornea while ensuring comfort and effectiveness in vision correction.

When choosing a diameter within this range, practitioners consider factors such as the curvature of the patient's eye, the size of the cornea, and the overall comfort level for the wearer. Lenses that are too small may not provide adequate coverage, which can lead to discomfort or inadequate vision correction, while lenses that are too large can affect the lens stability on the eye and could lead to complications such as lens displacement.

In practice, most commercially available soft contact lenses adhere to this diameter guideline to enhance the wearer's experience and ensure a proper fit that supports eye health.
