Gleyemor3PCS Magnetic Clip On Sunglasses for Men & Women Polarized UV Protection Retro Square Night Driving Glasses (Silver)

I decided to give this as a gift to my father. I think it's important for people to have it if they have any type of vision issues especially at night. So the glasses are able to come together magnetically so that you can look stylish at the same time. The yellow glasses helps a lot with his night driving because he does work late nights as a security guard and I want to make sure that he's safe while driving and while at his post. I asked him if he liked it he said yes he really likes funky gadgets such as these things. I may even get another pair for myself because I do have a little problem seeing certain things at night I have to really concentrate when I'm driving

The clip on sunglasses are actually magnetic and will attach to your existing glasses as long as they are metal and have a curve to them. If you don't need to wear glasses at the same time then these are great and will work.
