How Your Prescription Determines Which Contact Lenses Work Best

When it comes to achieving clear, comfortable vision with contact lenses, your prescription plays a crucial role. At Primary Vision Care, we take the time to ensure your lenses match your eyes’ unique needs through a detailed contact lens exam and fitting. Understanding how your prescription impacts your lens options can help you make more informed decisions about your vision care.

 

Understanding Your Contact Lens Prescription

A contact lens prescription includes more details than a glasses prescription. While both aim to correct refractive errors like nearsightedness, farsightedness, or astigmatism, contact lens prescriptions also account for factors such as:

•          Base Curve (BC): Indicates the curvature of the lens to fit the shape of your cornea.

•          Diameter (DIA): Determines how the lens sits on your eye’s surface.

•          Lens Material and Brand: Some eyes tolerate certain materials or designs better than others.

Your optometrist uses specialized instruments to measure your eye’s surface and assess how tears interact with the lens to ensure the right fit and comfort.

 

Matching Lens Type to Your Vision Needs

Your prescription helps your eye doctor recommend the best lens type for your eyes and lifestyle:

•          Single Vision Lenses: Designed for correcting one field of vision—either distance or near.

•          Toric Lenses: Ideal for those with astigmatism, as they correct uneven curvature in the cornea.

•          Multifocal Lenses: Great for patients with presbyopia, providing clear vision at multiple distances.

•          Specialty Lenses: For conditions like keratoconus or severe dry eyes, specialty contacts (such as scleral lenses) provide better stability and comfort.

The strength of your prescription, combined with your corneal shape and eye health, determines which of these options will deliver the sharpest, most comfortable vision.

 

The Importance of a Professional Contact Lens Exam and Fitting

A contact lens exam and fitting at Primary Vision Care ensures your lenses are not only the correct power but also the proper shape and material for your eyes. Even small differences in fit can affect comfort, vision quality, and eye health. During your visit, your optometrist will:

•          Measure your corneal curvature and tear film.

•          Recommend lens materials that best suit your eyes and lifestyle.

•          Evaluate the lenses on your eyes and make any necessary adjustments.

This personalized approach helps prevent issues such as irritation, dryness, or blurred vision while maximizing comfort and clarity.
