I purchased computer glasses at common eyewear shop JINS yesterday since I work in front of computer whole day.
JINS is growing brand in Japan because of its reasonable price and variety kinds of glasses.
JINS PC is one of their popular products. They started selling JINS PC with prescription glasses recently, so I ordered the one. I paid for it about JPY10,000 or $125 and waited for a few weeks.
The bottom one is JINS PC and the top is my regular one. PC’s glasses tint a bit.
The weight is slightly lighter. I wore them all day today, but did not feel difference yet. Maybe, I need a couple of days or so to see if these ease my eyes strain.
Technically, they do so no matter how I feel. They cut some blue light emitted from computer screen by 50% at maximum. I hope this helps reducing eye strain, but also improving focus on computer work.
