Final answer:

Ortho-K steps include corneal mapping, lens design, patient education, lens dispensing, and follow-up care. Light travels from the cornea to the retina, where the lens focuses it, and rods and cones process it into images.

Step-by-step explanation:

The correct sequence for Ortho-K (orthokeratology) process generally includes corneal mapping, lens design, patient education, lens dispensing, and follow-up care, which corresponds to option A) Corneal mapping, lens design, patient education, lens dispensing, follow-up care. This process is for nighttime lenses that temporarily reshape the cornea to correct vision.

Now, answering the reviews and questions:

  1. The path of light through the eye travels from the cornea, through the aqueous humor, entering the lens, passing through the vitreous humor, and finally hitting the retina to create an image.
  2. The cornea is the clear, dome-shaped front surface of the eye that helps to focus incoming light onto the retina.
  3. The lens of the eye adjusts its shape to focus light onto the retina for clear images at various distances; this is known as accommodation.
  4. Rods and cones are two types of photoreceptor cells in the retina; rods are responsible for vision at low light levels, while cones are responsible for color vision and function best in relatively bright light.
