Contact lenses sit directly on your eyes, whereas glasses are about 12mm away. This difference changes how lenses refract light into your eyes. Contact lenses provide more accurate refraction, which can make high prescriptions feel stronger. Visit your eye care professional to ensure both prescriptions are optimized for your vision needs.

FAQs & Answers

  1. Why is my contact lens prescription different from my glasses prescription? Contact lenses sit directly on the eye’s surface, resulting in a different lens-to-eye distance compared to glasses, which are typically about 12mm away. This positional difference affects how light is refracted, causing variations in prescriptions.
  2. Can I use the same prescription for both my glasses and contacts? No, glasses and contact lenses prescriptions are usually different because of the lens position. Contact lens prescriptions are adjusted to account for the lens sitting directly on the eye.
  3. How can I ensure my glasses and contact lenses prescriptions are accurate? Visit your eye care professional for regular eye exams and inform them about your use of both glasses and contacts so they can optimize each prescription for your specific vision needs.
