Since its launch in 2008, Groupon has radically transformed the world of online shopping. The group buying site currently boasts over 70 million subscribers who adore the site’s daily discounts on everything from pedicures to sushi dinners.
Everyone loves saving money, and with Groupon consistently offering $100 massages for as little as $25, for instance, and $50 meals for $15, it has become a friend of many. The service attracts consumers, promotes local businesses, and ultimately helps to build long-lasting business relationships.
Reflection and glare can hurt the user experience
If you accept Groupon at your place of business and use the Groupon Merchant App to keep track of customers and bookings, or to accept credit card payments, you probably find yourself staring into a screen for the better part of the day. According to medical experts, this can be harmful to your eyes.
The name for eye problems caused by extensive computer use is computer vision syndrome (CVS). Research has shown that between 50 to 90 percent of all mobile device and computer users have CVS symptoms of some sort. You can probably guess why computers cause so many more eye problems than, say, reading from paper: To a large degree, the flicker, contrast and glare of computer screens is the main culprit.
