Normally, any frame could be changed into prescription sunglasses. Preferably avoid getting cheap or "non rx-able" [http://lucyyou.com/mat-kinh-thoi-trang mat kinh thoi trang] frames plus the extreme cover type since these make a difference to the visibility along at the corner with the lenses. These are typically suitable only up to specific power. Sunglasses having a shield design may also be not suggested for prescription sunglasses.

When you have vision problems that require wearing bifocal lenses or progressive lenses, it is easy to find prescription sunglasses for you. It is possible to select many different excellent lenses for example polycarbonate, plastic, Trivex and glass.  Trivex is considered the best due to the durability. Polycarbonate just isn't the best choice if you plan to consider tinted lenses.

Prescription sunglasses can be tinted or plain. Although blue and yellow are thought trendy the recommended shade is brown since it is the best option for protecting your eyes from your sun. A high level athlete or play tennis, golf or other outdoor sports, you should have accurate seeing as well as capacity to differentiate contrast. Grey can be another great option for its power to shut the sunshine. Blue isn't your best option as it might cause a glare.

Finally, clip on prescription sunglasses are a choice for all on a budget, besides providing you the ease of carrying them around along and wearing them on the move. You can simply clip them onto your regular prescription glasses. These are, however, much less effective for a proper couple of sunglasses when they tend not to do a sufficient job of guarding your eyes in the sun. There is a choice of "fit-over" frames which are over your regular glasses, with no need to bring them off. They also steer clear of the side glare a result of clip-ons.

The Adventure Starts Here

Geohashing is a global game of spontaneous adventure generation with over 17,000 expeditions since 2008. You will explore random locations, meet fellow geohashers, brave the elements, unlock achievements, and then come back here to document your expedition.

—Felix, about a hash
The Algorithm was invented for xkcd comic #426, published on 21 May 2008.

How to play?

  1. Get today's coordinates with a coordinate calculator
  2. Go there (or as close as you safely and legally can)
  3. Create an account (Returning after a break? All accounts created before 2020-02-02 were deleted; you'll need to sign up again)
  4. Write about your expedition!

How does Geohashing work?

Everyday, an algorithm generates a random coordinate from stock market data. That coordinate can be applied to every 1°×1° latitude/longitude graticule in the world, giving a point that might be in a field, a forest, a city, or even out at sea! Everyone in the world gets the same set of coordinates relative to their graticule.

Each day, people try to get their nearest generated coordinate, for an adventure, to discover somewhere new, or to meet up with other geohashers. Afterwards, you can document your expedition. The rest of us would love to read your story, see your photos, and cheer your success (or commiserate with your failure)! Join the other 'spot spotters', be out standing in your field and use this wiki to document the daily coordinates (geohashes) you’ve been to or tried to reach.

Each day there is also a single globalhash somewhere on Earth: rare, valued and much harder to reach.

Official xkcd meetups

Felix Dance, Mdixon4, Rhonda, Lachie and Stevage meet up at the 28 December 2015 (a Monday) coordinates for Bairnsdale, VIC, Australia.

Based on the title text from the comic that established geohashing, the "official" meetup day was interpreted as being Saturday; that is, the day one would have the best chance of meeting others -- see also Mouseover Day. Additionally it was decided through convention that a good meeting time would be 16:00 local time (4:00 P.M.)¹

However, neither of these are hard rules, and they were formulated at a very different early stage in the sport's history. Nowadays and for quite awhile actually, any date or time can be good (or bad, depending on how many other hashers are near you) for meeting up, especially if prearranged. Note that this only applies to that day’s normal local geohash or globalhash coordinates, if you try to go to an alternate location without telling anyone else, it's highly unlikely you'd meet up with a hasher there (obviously).

¹Or earlier if that would be too close to sunset during the winter, or other quirks of temporal tradition; see your local graticule page for consensus there.

Gallery of recent expeditions

Every expedition should have one photo in that day's gallery, selected manually. Please add yours with the "add" link. If that day's gallery hasn't been started yet, please start it.


Recent Expeditions


Recent and Upcoming Coordinates

The coordinates for the next Saturday meetups, scheduled for 23 November 2024, will be based on the Dow’s opening price published at 09:30 EST (14:30 UTC) on Friday 22 November. See timeanddate.com to convert this time to your local time zone.

Disclaimer: When any coordinates generated by the Geohashing algorithm fall within a dangerous area, are inaccessible, or would require illegal trespass, DO NOT attempt to reach them. Please research each potential location before attempting to access it. You are expected to use proper judgment in all cases and are solely responsible for your own actions. See more guidelines.
