Sunglasses UV

Introduction

Sunglasses brands have expressed that they shield eyes from the U.V. rays that the sun emit. However, the U.V. rays are penetrating but can be stopped by a piece of paper or any plastic object. This experiment investigates whether the different brands of sunglasses will better shield the eyes from U.V. rays.

In this experiment, a model UBGL-15 Mineralight Lamp was used to emit the U.V. light. The sunglasses brands that were tested were bears sunglasses, Ferrari sunglasses, minecraft sunglasses, and Monmouth College sunglasses were tested.

Figure 1:The graph shows absorbance plotted against the wavelength in nano meters. The red line show the U.V. light without any type of glasses in front of the detector while the black line represents all of the glasses in front of the photodioarray detector while emitting U.V. light.

Result and conclusion

The results show that all sunglasses (black line of Figure 1) prevented all of the waves from piecing the sunglasses. This means that all sunglasses, regardless of cost, still prevent the same amount of U.V. rays from penetrating the eyes. The safety glasses did allow for one 400 nm peak to be shown which is due to all the other sunglasses having tinted to reflect out red light.
