The eyes-in-the-front thing (usually) only applies to mammals. Crocodiles, arguably the inspiration for dragons, have eyes that look to the sides despite being a predator.
hey what up I’m about to be That Asshole
This isn’t a mammalian thing. When people talk about ‘eyes on the front’ or ‘eyes on the side,’ they’re really talking about binocular vision vs monocular vision. Binocular vision is more advantageous for predators because it’s what gives you depth perception; i.e, the distance you need to leap, lunge, or swipe to take out the fast-moving thing in front of you. Any animal that can position its eyes in a way that it has overlapping fields of vision has binocular vision. That includes a lot of predatory reptiles, including komodo dragons, monitor lizards, and chameleons.
(The eyes-in-front = predator / eyes-on-sides = prey thing holds true far more regularly for birds than it does for mammals. Consider owls, hawks, and falcons vs parrots, sparrows, and doves.)
But it’s not like binocular vision is inherently “better” than monocular vision. It’s a trade-off: you get better at leap-strike-kill, but your field of vision is commensurately restricted, meaning you see less stuff. Sometimes, the evolutionary benefit of binocular vision just doesn’t outweigh the benefit of seeing the other guy coming. Very few forms of aquatic life have binocular vision unless they have eye stalks, predator or not, because if you live underwater, the threat could be coming from literally any direction, so you want as wide a field of view as you can get. If you see a predator working monocular vision, it’s a pretty safe assumption that there is something else out there dangerous enough that their survival is aided more by knowing where it is than reliably getting food inside their mouths.
For example, if you are a crocodile, there is a decent chance that a hippo will cruise up your shit and bite you in half. I’d say that makes monocular vision worthwhile.
Which brings us back to OP’s point. Why would dragon evolution favor field of view over depth perception?
A lot of the stories I’ve read painted the biggest threats to dragons (until knights with little shiny sticks came along) as other dragons. Dragons fight each other, dragons have wars. And like fish, a dragon would need to worry about another dragon coming in from any angle. That’s a major point in favor of monocular vision. Moreover, you don’t need depth perception in order to hunt if you can breathe fucking fire. A flamethrower is not a precision weapon. If you can torch everything in front of you, who cares if your prey is 5 feet away or 20? Burn it all and sift among the rubble for meat once everything stops moving.
Really, why would dragons have eyes on the front of their heads? Seems like they’ve got the right idea to me.
this is some good dragon discourse right here, 10/10, and i dont mean to derail the whole thing away from the eyes, but i feel obligated to mention that in many stories and accurate to some reptiles, dragons have an extremely acute sense of smell/taste which would definitely help narrow down the depth perception issue. things smell stronger the closer they are. and i feel like i read somewhere that a blind snake can flick the air with its tongue and track its target mouse with no trouble at all. gotta imagine the “great serpents of the sky” had some pretty advanced biology. enough to make field of view win out against depth perception.
anywho. cool stuff. fear the dragons even if they are the prey cause they still beat us on the food chain.
where are those startups that are disrupting the glasses industry
zenni and it’s amazing and i love it 40 dollar bifocals fuck yeah
Hey I’m reblogging this again because if you need glasses here’s what I do:
Go to Costco/Sams Club/WalMart – wherever they’ve got that $58 eye exam. That’s with no insurance, btw. Just $58 cash on the counter, you get your eyes examined.
They’ll give you a copy of your prescription. ASK THE DOCTOR TO MEASURE YOUR PUPIL DISTANCE. If they don’t it’s not a huge deal, you just have to have a ruler around that has millimeters so you can measure it yourself and it won’t be as accurate but being off by as much as a centimeter isn’t a problem.
Make them give you a copy of your prescription – you are allowed to have this, they have to give you it, you don’t have to buy glasses there. If anyone challenges you say you need a copy for your records and you’re not going to buy glasses today.
Go to https://www.zennioptical.com/ and start looking at frames/glasses that you like. If you create an account it’ll let you upload a photo and based on your pupil distance the site will estimate how well various frames will fit you.
Add the frames you like to cart and start checking out – the checkout process will ask you for your RX details that will be written in the boxes on your RX page. It’s pretty intuitive to copy it over but if you get lost use the livechat feature on the zenni page.
Start selecting your glasses details. Your RX will determine what kind of lens you get (go with the one zenni recommends for materials and thickness) but your needs will determine the other stuff. I make sure to get the fancy oleophobic coating because I’m a slimy bog monster. I also get the cheapest pair of sunglasses possible because bog monsters hate the sun. You can get transitions lenses or anti-scratch coating or super lightweight lenses or whatever works best for you. The extras will add up in cost but you gotta do what you gotta do – my life is much better with a pair of sunglasses than it is with some clip-ons for my regular glasses; your life may be better with transitions lenses instead of carrying a second set of glasses. DO WHAT WORKS BEST FOR YOU.
Don’t bother paying the rush shipping, this is going to take two weeks regardless.
GLASSES ARRIVE. WEAR GLASSES.
If the fit isn’t perfect see if the place that did your eye exam will adjust the fit for you. They often will free of charge.
GLASSES. GLASSES. I CAN SEE.
PROGRESSIVE BIFOCALS THAT COST $40 WITH CUTE FRAMES AND NICE COATING.
SUNGLASSES.
FUCK
It costs less for me to get two pairs of bifocals, one tinted and one clear, with special coatings and nice frames than it would cost me to get one pair of single-vision glasses from Warby Parker.
The cheapest frames available for adults on Lenscrafter’s site is $69.95. That is JUST the frames, not the lenses. The lenses are like $200. The anti-glare coating is like $70. THE ANTI GLARE COATING IS FREE AND INCLUDED WITH YOUR PURCHASE AT ZENNI. Just the frames and the coating at lenscrafters costs more than my two pairs of glasses AND my eye exam.
I can’t articulate how many literal headaches Zenni has saved me because I just used to wear my old prescription until I had trouble keeping my eyes open from the strain. Now at the first hint of eye strain it’s like “Not today, Satan!” and I can plan for the $100 expense that’s going to last me potentially years.
Obligatory reminder that a ton of people have added but still, Zenni and other likewise sites (1-800-Contacts) require the prescription be up to date within a year. So yeah plan that in, any time you shop, that script has to be from within the last year.
I would also like to submit glassesshop.com because, though I shopped Zenni exclusively from 2012-2017, in the last six months I have gotten four pairs of glasses from GlassesShop, and still paid less than a hundred dollars.
The key difference for me was that while Zenni was utterly eye opening (ha, eye pun), they rarely do sales, and GlassesShop is constantly rolling through a variety of sales. There is almost always a wide selection of glasses on Buy One Get One Free promotion, and the free pair includes the lenses, no matter what add ons are on there or whatever kinda prescription you got, as long as its the less expensive pair.
They also do weekly specials where rotating selections of frames go on clearance-rate pricing, from $6.95-12.95. This is just the tip of the iceberg of the constant variety of sales, promotions, and discounts they offer, and doesn’t include that, also unlike Zenni, if you have an account every purcahse you make accrues points which can be applied in dollar amount to future purchases, even with discounts/sales/promos also applied.
Like Zenni, GlassesShop lets you upload a selfie to “try on” frames you’re interested in, but they have a much wider selection and variety. They take about the same amount of time as Zenni to craft and ship your glasses, and they’re on par as far as quality and accuracy of prescription goes.
I will always be grateful to Zenni for opening the door for me on the online glasses market, because as someone netting less than 20k a year after taxes glasses used to be a “upon pain of death/causing a car accident from blindness” purchase but have become a “well that’s a great sale and I LOVE those frames… I guess I could do with another pair of glasses, there’s $30-50 in my budget!” kind of thing, and that’s incredible.
But I probably won’t be switching back, as after having made multiple purchases, the only thing I like better about Zenni compared to GlassesShop is Zenni has better cleaning cloths.
Regardless, they’re two excellent, amazingly affordable alternatives to spending minimum of $100 at a brick and mortar glasses store, and I’ve turned into something of a proselytizer for both, because people deserve to know they have these options.
It’s bad enough we’re out here paying to see, but too many of us don’t realize we could be paying a lot less to see, and in the cutest glasses best suited to our tastes, instead of whatever’s “cheap” at WalMart.
also gonna throw out eyebuydirect, which does some great sales. I’ve gotten prescription glasses as cheap as $6 and prescription sunglasses for $20.
Ordered from both Zenni and Eyebuydirect before and a great experience every time. I just bought two new pairs from Eyebuydirect. I upgraded to their blue filtering lenses (didn’t expect a huge difference but woah, it was definitely worth the upgrade) and with the sale going on, I paid less than $60.
eyebuydirect is legit
though I still remember the chuckle I got when that resident asked if I had warby parkers and I told him where they really came from
A group of rough looking boys walked past me today and all I heard of their conversation was “he’s got that anxiety disorder bro so I went with him so he’d be more comfortable” and it made me realise the world isn’t all that bad
The pet store I worked at had a pen with rabbits near the front door. On every side of the pen were huge signs saying “You can pet me, but don’t pick me up!” One day two absolutely huge guys came in and one immediately reaches into the pen to grab a rabbit. Before i could say anything his friend grabbed his arm and asked him “did you see the sign?” He said “yeah! it says that you can pick them up but don’t pet them!” Then he went quiet for a moment and softly said “I didn’t read it right did I?” And his friend just puts his arm on his shoulder and said “its ok, i know you’ve got that thing where words get mixed up. Let just pet these cute lil shits” And I still haven’t gotten over that interaction.
I was walking my dog through Boston bc he likes the likes car rides. He’s a little thing tbh we call him short and long. So this huge scary man with a full beard approaches me like “hey can my buddy and I pet your dog? He gets nervous around dogs but your’s is so small I think it’s a good place to start.” Ofc I was like “yes he’s very friendly!” So this guy brings his equally big friend over and they sit on the floor while this man looks terrified of my tiny dog so big man number one asks “can I pick him up?” And i say yes so he picks him up and puts him on man number two’s lap and man number two is abt to freak out and his friend straight up just goes “hey man, it’s okay just relax I’d never let anything hurt you. He’s a good boy.” I’ll never forget it ever bc I know that man looked at me (5’3 , glasses, probably wearing a sweater vest) and my dog (kinda goofy looking little thing) and was like ‘ah yes the two least intimidating living things I’ve seen in Boston all day he’ll feel relaxed around them’ and went out of his way to help his friend. It makes me so happy
My husband had this Dungeons and Dragons group ages ago, and one of the guys was TERRIFIED of cats. The moment he sees one he freezes up and can barely breathe. Said guy is almost seven feet tall and solid wall of muscle. Whenever he came over I’d put the cats in the bedroom and chill out with a book because my cats don’t like being shut away without one of us.
One of my cats was pawing at the door and meowing loudly, an indication she REALLY needs to use the litter box. I let her out and decide, hey, I’m hungry, and decide to the kitchen. I forgot to shut the bedroom door.
Next thing I hear is the group going completely silent. My husband very calmly asks me to come over and help him gather our two cats up. I go over to where the group is and my black cat, Cacoa, is rubbing up against the guy’s leg, purring, and doing her “let me on your lap” meow. The other cat, Jasper, is sitting at the window, chilling out. I go over and pick up Cacoa and tell the big dude she’s harmless, loves laps, and would be thrilled if he pet her. Very slowly he touches my cat’s face, and she leans right into his hand. He then pets her back and sighs because she’s really soft and purring like mad. After a few minutes he asks how to pick her up and if it’s okay if she sits on his lap.
He spent the next six hours spoiling my cat. The next week he showed up with cat treats and toys because he fell in love with the cats. He told me he was doing some research on house cats, and even talked to a vet about them. A couple months later he adopted two cats and was as thrilled and excited as a new parent.
Oh no a new one!!!
Blessed post.
I used to work at this stable for icelandic horses and every now and then this man would turn up by the field to just watch the horses. One time I walked by him as I was going to get the horses inside, and he went ”I always wanted to learn how to ride but I’m afraid of horses because they’re so huge. If I could ride ponies like this, maybe I’d dare but now I’m too big and heavy for them.” You should have seen his face when I told them that actually they’re not ponies, just small horses and they could totally carry him. His face just lit up. Next thing I’m helping him to get on back. Today he knows how to ride.
omg this is so pure ❤
take your time to read this, it’s totally worth it
@blvnk-art I heard you need some uplifting stories …
Medieval castle stairs were often built to ascend in narrow, clockwise spirals so right-handed castle defenders could use their swords more easily. This design put those on the way up at a disadvantage (unless they were left-handed). The steps were also uneven to give defenders the advantage of anticipating each step’s size while attackers tripped over them. SourceSource 2Source 3
Not really the best illustration since it totally negates the effect by having a wide open space for those ascending. Castle tower staircases tended to look like this:
Extremely tight quarters, with a central supporting pillar that is very, very thoroughly in the way of your right arm.
Wider, less steep designs tend to come later once castles moved away from being fortresses to simply noble family homes with the advent of gunpowder.
Oh! Pre-gunpowder military tactics are my jam! I don’t know why, but this is one of my favorite little details about defensive fortifications, because the majority handedness of attackers isn’t usually something you think about when studying historical wars. But strategically-placed walls were used basically worldwide as a strategy to secure gates and passages against advancing attackers, because most of the world’s population is right-handed (and has been since the Stone Age).
Pre-Columbian towns near the Mississippi and on the East coast did this too. They usually surrounded their towns with palisades, and they would build the entrance to the palisade wall in a zigzag – always with the wall to the right as you entered, to hinder attackers and give an advantage to the defender. Here’s some gates with some examples of what I’m talking about:
Notice that, with the exception of the last four (which are instead designed to congregate the attackers in a space so they can be picked off by archers, either in bastions or on the walls themselves) and the screened gate (which, in addition to being baffled, also forces the attackers to defend their flank) all of these gates are designed with central architectural idea that it’s really hard to kill someone with a wall in your way.
In every culture in the world, someone thought to themselves, “Hey it’s hard to swing a weapon with a wall on your right-hand side,” and then specifically built fortifications so that the attackers would always have the wall on their right. And I think that’s really neat.
Ooh, ooh, also: Bodiam Castle in Sussex used to have a right-angled bridge so any attacking forces would be exposed to archery fire from the north-west tower on their right side (ie: sword in the right hand, shield on the useless left side):
These tactics worked so well for so long because until quite recently lefties got short shrift and had it trained (if they were lucky) or beaten out of them.
Use of sword and shield is a classic demonstration of how right-handedness predominated. There’s historical mention of left-handed swordsmen (gladiators and Vikings), and what a problem they were for their opponents, but that only applies to single combat.
A left-handed hoplite or housecarl simply couldn’t fight as part of a phalanx or shield wall, since the shields were a mutual defence (the right side of the shield covered its owner’s left side, its left side covered the right side of his neighbour to the left, and so on down the line) and wearing one on the wrong arm threw the whole tactic out of whack.
Jousting, whether with or without an Italian-style tilt barrier, was run shield-side to shield-side with the lance at a slant (except for the Scharfrennen, a highly specialised style that’s AFAIK unique.) Consequently left-handed knights were physically unable to joust.
The construction of plate armour, whether specialised tournament kit or less elaborate battle gear, is noticeably “right-handed“ – so even if a wealthy knight had his built “left-handed” it would be a waste of time and money; he would still be a square peg in a world of round holes and none of the other kids would play with him.
Even after shields and full armour were no longer an essential part of military equipment, right-hand use was still enforced until quite recently, and to important people as well as ordinary ones – it happened to George VI, father of the present Queen of England. Most swords with complex hilts, such as swept-hilt rapiers and some styles of basket-hilt broadsword, are assymetrical and constructed for right handers. Here’s my schiavona…
It can be held left-handed, but using it with the proper thumb-ring grip, and getting maximum protection from the basket, is right-handed only. (More here.) Some historical examples of left-hand hilts do exist, but they’re rare, and fencing masters had the same “learn to use your right hand” bias as tourney organisers, teachers and almost everyone else. Right-handers were dextrous, but left-handers were sinister, etc., etc.
However, several
predominantly left-handed
families did turn their handedness into advantage, among them the Kerrs / Carrs, a notorious Reiver family along the England-Scotland Borders, by building their fortress
staircases with a spiral the other way to the OP image.
This would seem to be a bad idea, since the attackers (coming upstairs) no longer have their right arms cramped against the centre pillar – however it worked in the Kerrs’ favour because they were used to this mirror-image of reality while nobody else was, and the defender retreating up the spiral had that pillar guarding his right side, while the attacker had to reach out around it…
For the most part Reiver swords weren’t elaborate swept-hilt rapiers but workmanlike basket-hilts. Some from Continental Europe have the handedness of my schiavona with thumb-rings and assymmetrical baskets, but the native “British Baskethilt” is a variant of the Highland claymore* and like it seems completely symmetrical, without even a thumb-ring, which gives equal protection to whichever hand is using it.
*I’m aware there are those who insist “claymore” refers only to two-handers, however the Gaelic term claidheamh-mòr
– “big sword” –
just refers to size, not to a specific type of sword in the way “schiavona” or “karabela” or even “katana” does.
While the two-hander was the biggest sword in common use it was the claidheamh-mòr; after it dropped out of fashion and the basket-hilt became the biggest sword in common use, that became the claidheamh-mòr.
When Highlanders in the 1745 Rebellion referred to their basket-hilts as claymores, they obviously gave no thought to the confusion they would create for later compilers of catalogues…
Also, muskets had their whole “Flint and steel and gunpowder” thing on the right side so if you tried firing it lefty you’d get a face full of fire. More recently, rifles eject their spent shell casings to the right, so if you’re a lefty you get some hot metal in your eye.
