Why do we prescribe glasses for the visually impaired population?

• A. Maximizes VA/visual potential, provides protection (polycarb, trivex, UV), allows for tints, polarization, and AR, and maximizes magnification devices at distance and near.
• B. To ensure all patients wear glasses.
• C. To fulfill clinic mandates.
• D. To change eye color.

Answer: (A)

Prescribing glasses for the visually impaired is about maximizing visual acuity and functional vision. Corrective lenses help sharpen distance and near vision, enabling individuals to use magnification devices more effectively and perform everyday tasks with better clarity. Beyond basic correction, lenses can be made from impact-resistant materials like polycarbonate or Trivex, which protect the eyes and provide UV protection—important for safety and comfort. Lenses can also be tinted, polarized, or coated with anti-reflective treatments to reduce glare, enhance contrast, and improve comfort in varied lighting. All these features work together to optimize how well someone can see and function in daily life. The other statements miss the core purpose: glasses aren’t prescribed just to ensure everyone wears them, to fulfill mandates, or to change eye color; they are prescribed to improve vision, protection, and practical usability.
