Diane Hill, from Coventry, felt that existing smiling, sleepy and sad faces did not represent the lives and likes of older people.
The 56-year-old compiled her own "emoldjis" for the over 50s.
An artist sketched her ideas which were sent to off to the Unicode Consortium which regulates emoji updates.
Ms Hill said: "I need something that shows pain because my back hurts, my knees hurt and I need emojis with glasses."
She came up with the idea as part of a BBC outreach project about how the media reflects the people and places around them.
Local artist Chris Oxenbury was commissioned to formally design her suggestions and sketches which have now been sent off for approval.
If successful, smartphone users could see designs such as "older person looking disapproving over glasses", "spending the kids' inheritance", and "no budgie smugglers" just a thumb-swipe away.
"When I first saw them I thought they were fantastic," Ms Hill said.
"I love the 'spending the kids inheritance one'.
"I could send any of these emojis to my friends and they'd know what I mean."
Siobhan Harrison, from the Open Doors project at BBC Coventry & Warwickshire, said: "With new emoji characters only released by Unicode on an annual basis it could be over a year before Diane's emojis hit our screens but at least she has raised some interesting issues about how the media reflect older people's lives and had some fun along the way."
Experts said last year "emoji language" is the fastest growing in the UK with millions of people choosing the digital images over written text.
The word emoji literally means "picture" (e) + "character" (moji) in Japanese and was added to the Oxford English Dictionary in 2013.
False teeth and bad back emojis, the brainchild of a frustrated grandmother, could soon be in use after being sent off for official approval.

Now, Sir David Attenborough has uncovered the world's biggest known dinosaur for his latest documentary.
The new species was 37 metres long - about the length of four London buses.
He told Newsround he believes there's a very small chance the prehistoric beasts could be brought back from extinction.
But he said that it would be very expensive, and it would be better to concentrate on looking after the animals we already have.
You can watch the first of Sir David's new series 'Attenborough And The Giant Dinosaur' on Sunday 24 January, at 6.30pm on BBC One.
They stalked the earth around a hundred million years ago and scientists are constantly looking for new dinosaur fossils.

It has acquired 187 patents and 36 applications, adding to the 1,000 it purchased from IBM last summer.
The latest patents include a system for "using semantic networks to develop a social network".
Google has spent billions building its technology rights portfolio, including a $12.5bn (Â£7.7bn) deal for Motorola Mobility.
The California-based company has been actively bolstering its patent catalogue in the face of lawsuits from key competitors such as Apple and Microsoft.
Among the patents acquired in this latest deal isUS Patent 7,865,592which relates specifically to social networking sites, allowing "identifying common interests between users of a communication network".
Vicki Salmon, the chair of the litigation committee of the UK Chartered Institute of Patent Attorneys, believed this might be a nod that Google was moving from protecting existing technology and beginning to plan for the future.
"When you start you have to play catch-up," she told the BBC.
"When you've finished playing catch-up and you've got yourself in a stronger position, you then can begin to look forward."
Other patents included a method forusing web-based applications across additional devices, and an intriguingly titledcomputer phone.
Neither Google nor IBM would comment on the deal when approached by the BBC.
Last year, Google accused its competitors of buying up what it called "bogus patents" in order to slow the development of its Android operating system.
However, the company now appears to have succumbed to the same approach as it adds the IBM patents to a portfolio that also includestechnology for driverless cars.
"Although you can object to a lot of cost of inconvenience by virtue of people enforcing their patents, the patent system still exists," Piers Strickland, a lawyer specialising in mobile telephone patent litigation, told the BBC
"In order to engage with that you've either got to take licences from from people's patents, and/or aggressively increase your bartering position by buying patents.
"I think they've realised that they just had to get real, and understand that you can't just ignore the system."
Google's agreement to buy Motorola Mobility,announced in August last year, includes 24,500 patents, many of which could be used to defend the use of features on its Android mobile operating system.
The purchase is currently beingreviewed by competition regulators.
Google's Motorola move came off the back oflosing out on buying the 6,000-strong patent portfolioof bankrupt telecoms firm Nortel. It was outbid by a consortium of companies including Apple, Microsoft and Blackberry manufacturer Research in Motion.
"The reality is that you've got a fairly vicious turf war going on between the different operating systems," explained Ms Salmon.
"People want to be in there, and they want their platform established and people to be using them."
Google is just one of many technology companies involved in patent lawsuits which seek to slow down competition or strike lucrative licensing fee settlements.
On Wednesday, US mobile operator AT&T was forced to pay Tivo - the digital video recorder specialist - $215m plus additional undisclosed monthly licensing fees.
The fee will vary depending on AT&T meeting growth targets for digital video recording customers until 2018.
"No matter which projections you take, they all involve AT&T paying us significantly higher revenue than $215m," Tivo chief executive Tim Rogers said.

Google has gained hundreds of patents from IBM as it continues its intellectual property spending spree.
