     Have you ever wondered how watching six whole seasons on Netflix can affect your eyes? What about just using a computer at school? There is a type of non-visible light to the human eye, similar to UV light, that can damage your retina. Your retina is a thin layer of tissue in the back of your eye that receives light. There are certain types of visible/ non visible light that can damage it. One example is blue light, blue light can affect you in many ways. Blue light comes from fluorescent lights or LED screens. How does it affect you? Well, many studies have shown that blue light can affect your circadian cycle, also known as your sleep cycle. Teenagers spend an average of 9 hours on screens every day. That’s a lot of blue light which adds up and can damage ones retina to the point where sleeping is a struggle. There are glasses with special lenses that block blue light so it can not travel to your retina. They can be purchased online for a good price ranging from ten to thirty dollars. The lenses can also be added to prescription glasses if necessary. 

     I conducted my own experiment with these glasses to see if they worked. My results showed that for the five days I did not wear the glasses, I woke up in the middle of the night almost every night! The week I wore the blue light blocking glasses, I did not wake up once throughout the night and felt very well rested. In conclusion, I definitely benefited from wearing these glasses, and I will try to wear them whenever I can!
