No Explanation: As it stands, "contrast" is used as an adjective and in this sentence "the" is not needed. If the writer means to say "Effect of acupuncture stimulation on the contrast between visual acuity and photophobia" (I do not know the subject well enough to know if this makes sense or not), then it could be used but is still not essential. |
