ever since tony was young, he claimed he could only see shades of blue and yellow. on the other hand, javier cannot see any colors at all, just shades of gray. which of the following is true?
tony has been diagnosed with presbyopia.
javier is a monochromat and tony has a color deficiency.
both javier and tony have protanopia.
both javier and tony are at increased risk for macular degeneration.

Explanation:

Presbyopia is a condition related to aging - related loss of near - vision, not color vision, so the first option is incorrect. Protanopia is a type of red - green color blindness, which is not the case for either Tony or Javier described here. There is no information to suggest increased risk of macular degeneration. A monochromat cannot see any colors (sees only shades of gray), which describes Javier, and Tony has a color deficiency as he can only see shades of blue and yellow.

Answer:

Javier is a monochromat and Tony has a color deficiency.
