Lina wanted to buy a pair of sunglasses to wear outdoor on hot days when the sun is shining brightly. She collected data using a light sensor data logger. The table below shows the amount of light passing through the different types of lenses, A, B, C, D and E. 

Types of lenses	Amount of light passing through (Lux)
A	4850
B	4000
C	2000
D	825
E	300

Lina chose Lens E to be the most suitable material for making her sunglasses.

Do you think she has made the correct choice? Explain.
