Table 1 describes the variables. With regard to the
Theory of Planned Behavior variables, attitudes andall four behavioral control items had mean values
slightly above the midpoint toward more agreement.
Both intentions and social norms had mean values
slightly below the midpoint toward more disagreement. With regard to demographic variables, the age
was almost 23 years and slightly less than half were
men. Almost one-fifth were Asian Americans and the
other greatest ethnicity group of 17% were African
Americans. All other non-White groups were below
10%. With regard to symptom variables, the average
number of symptoms was four out of the 14. Mean eye
health was between very good and good. Less than 5%
received treatment for computer vision syndrome.
With regard to behavior related to supplements variables, one-quarter used eye supplements and less than
10% previously used eye drops for computer vision
syndrome. Use of a multivitamin for one’s health,
avoid eye supplements due to concern of side effects,
do not like using eye drops, and prefer swallowing eye
supplement rather than using drops all had mean
values near the midpoint between strongly agree and
strongly disagree. Only use of alternative medicine
treatments for my health was below the midpoint
towards disagreement. With regard to eye devices
placed in eyes variables, half wore glasses for improving their vision, slightly more than one-quarter wore
contact lenses for improving their vision and less than
10% wore contact lenses for cosmetic purposes.
Almost 5% had previously used the Eye Science
Computer Eye Strain formula.
Table 2 shows linear regression analyses for intentions to use the Eye Science Computer Eye Strain formula. With regard to the Theory of Planned Behavior
variables, increased attitudes, increased social norms,
increase in the confidence to use the Eye Science
Computer Eye Strain formula, and decreased decision
to use the Eye Science Computer Eye Strain formula is
beyond my control (reverse coded) were all
significantly associated with increased intentions.
With regard to demographic variables, none were significantly associated with intentions. With regard to
symptom variables, only increased total symptoms
were significantly associated with increased intentions.
With regard to behaviors related to supplements variables, only increased preference of eye supplements to
swallow instead of eye drops was significantly associated with increased intentions. None of the eye
devices placed in eyes variables were significantly associated with intentions. Also, use of the EyeScience
Computer Eye Strain formula was significantly associated with increased intentions.
Table 3 shows logistic regression analyses for use of
the Eye Science Computer Eye Strain formula. With
regard to the Theory of Planned Behavior variables
only intentions were significantly associated with
increased odds for use. With regard to demographic
variables, none were significantly associated with use.
With regard to symptom variables, those who had previously received treatment for computer vision syn-drome had significantly greatly increased odds for
use. With regard to behaviors related to supplements
variables, only previously using eye drops for computer
vision syndrome had significantly greatly increased
odds for use. None of the eye devices placed in eyes
variables had significant associations with use.
