The line graph illustrates the changes in the number of students choosing different eye colors for their contact lenses from 2010 to 2020. It compares three colors—brown, blue, and green—and highlights trends over the given timeframe.
Overall, brown was the most popular contact lens color throughout the period, showing a steady increase. Additionally, blue lenses experienced a sharp decline, while green lenses remained relatively stable with only minor fluctuations.
Looking at the graph in more detail, the percentage of students choosing brown contact lenses increased steadily from 30% in 2010 to 60% in 2020. This was the most significant rise among the three colors. In contrast, blue lenses declined sharply from 50% to 20% over the same period.
A closer look reveals that green lenses remained the least popular, fluctuating between 15% and 20% throughout the period. Similarly, despite an initial increase in the number of students choosing blue lenses in 2012, the trend reversed after 2015. Despite these variations, brown lenses consistently remained the most preferred choice.
