The presented line graph illustrates the color preferences of students regarding contact lenses from 2010 to 2020. The data is expressed in proportional terms.
Overall, green lenses were the least preferred over the 10-year period, as their popularity never exceeded that of the blue and brown colored lenses. On the other hand, the share of students choosing brown lenses shows an upward trend, while those who opted for blue lenses declined gradually.
Regarding blue lenses, exactly 50% of pupils preferred those in 2010. From this year onwards, the number gradually fell by roughly 4-5% every year, culminating in a figure of just 20% by the end of the measured period.
Furthermore, until 2014, the color brown was only the second most favoured alternative, it took the lead from then on, increasing considerably each year, eventually reaching its peak in 2020 by a proportion of 60%.
The popularity of green lenses, though fluctuated steadily, it remained relatively low across the given period.
