Bailey and PREDATOR - you say that you have experienced benefits of using these - that they reduce your eye strain. What sort of symptoms have help alleviated for you?
I spend hours on computer screens at work and then come home to spend 5 hrs at night playing games etc. As I am middle age I have been putting done my eye problems (perhaps headaches, blurred vision, sometimes dry eyes) etc to old age. I do have short sight and long sight prescription specs now though I don't use (unless I am at the cinema or reading small print) - my prescription should mean that I am OK to see 30cm to say 10m. These sound like they might actually be beneficial to me but I want to know more specifics why you are saying they are good.
I used to suffer with tired, sore, dry eyes after a full day at work, like yourself I also game in the evening after work. I am also incredibly susceptible to Headaches and Migraines (I have my Mother to thank for that). Having been using the Gunnars, I find that my eyes are not as fatigued come the end of the working day, they are not dry or sore. I have also noticed that I am not suffering from as many headaches. I do still get them but not as often. This I would put down to the "focusing Power" as Gunnar call it, a very slight magnification to the lenses that mean text is easier to read for example. The blue light reduction is great and believe it or not, the amber tinted lenses really don't affect colour that much, infact, i'd say you become used to it and dont really notice the slight tint - not until you take the glasses off. I stare at a lot of white screen during the day at work due to the nature of the job - this is where the lens tint helps, the lenses as stated, also help protect from screen glare/screen burn.
When I get home, I game on my home PC for a few hours, usually in a dark room due to sun or light reflection off of my monitor. The Gunnar's slight tint helps brighten the room up so i'm not straining when looking at the screen - helps on dark games too! Works similar to shooting glasses, brightens the environment up a little, just to take the strain off the eyes.
I'm no Optician or Ophthalmologist so I cannot go into Medical depth, however, I will say that they work. Gunnar had their lens design Medically Approved too!
In fact, put it this way, I brought a pair - even though I wasn't originally sold, like most other people, I was just using f.lux and other software for blue light reduction and I am honestly glad to say I was pleasantly surprised.
