I have pretty okay eyesight with slight astigmatism. My left eye is about 25 while my right eye is 50. Though with my job being a writer for international dating blogs, review blogs, and video editing, I spend most of my days in front of the computer. On some days, my head would start to ache and I wonder if it’s about time I invest on glasses. I’m not much of a spender so I’m doubting if I really do need them with my grade being so low. My headaches are probably from lack of sleep or something. I also hear that you can upgrade the lenses with anti-screen and anti-UV options. What do you guys think? For those with glasses, do you think it’s a wise decision to invest in them?
