The tank is a .7 gallon tank
this is much too small for a betta

I didn't think I needed a filter
i havent heard of self-cleaning tanks before, i read up on them though and they sound a bit dodgy. the two types are either one that uses a gravity-based pump to filter the water (basically a built-in filter of sorts) and theres a garden one where supposedly plants grown in the tank roof filter the water. i think your lack of filter likely screwed you over as well, especially in such a small tank.

I used to use spring water every three days and probably do a 25-50% water change but it didn't seem like it was cleaning it so I started doing 100% water changes every few days when I noticed his eye becoming bad.
using spring water, if it was unconditioned, was not a good idea since you dont know whats in the water and there could be all sorts of chemicals or heavy metals that would poison your fish. 100% water changes are very extreme since they kill off the bacteria cultures in the tank, its basically like if you put your betta into an uncycled tank every few days. this likely wouldve caused him a lot of stress, which wouldve weakened his immune system. id say thats why he got infected then.

our tap water here is hard .
bettas are softwater fish, so if you werent adjusting your water hardness chemically this wouldve made him sick too. in the future, you should avoid getting bettas because your water is unsuited to them. a good hardwater alternative is guppies. i strongly recommend you research the needs of any fish before buying them though. and remember that fishkeeping is an expensive hobby, and if you cant afford to get all the equipment you probably shouldnt get the fish.

To be honest I never even knew about the water parameters until he got sick
it is super duper important to test your parameters weekly at least! if you are going to continue keeping fish, make sure to buy a water testing kit and test your water regularly. also, your local fish shop might test your water for you if you bring in a sample. you should call them and see if they offer this service. if they do, bring in some of your tank water (at least 20mL) and get it tested.

I don't have any live plants I just have one fake plant like ornament and I did clean it before putting it in.
live plants are great because, while theyre more pricy, they oxygenate your water (so your fish can breathe) and get rid of the CO2 and ammonia your fish produces with their poo. if your plant is plastic or has sharp edges, your fish may have cut or snagged his fins and got infected. if you want fake plants, be sure that theyre silk.

I purchased the tank and conditioned the water and waited 24 hours to put him in.
its generally recommended to cycle your tank for a week before adding fish.

There's no other fish with him and I got him at a pet supplies plus
pet stores are generally dodgy and i would strongly advise you never buy any animal from one ever. they buy them cheap from breeding farms, meaning the animals usually have poor genetics and grow up in filthy environments. bettas are usually kept in tanks the size of drinking cups, lined up on a shelf next to other bettas. constantly being around enemies stresses them out, and their poor life quality means they can be sick before you even buy them.
most pet store workers dont know much about the actual care needed for animals, so theyll often tell you false information just to sell things. you should do a search and see if you can find any fish stores close by. the owners there will be much more knowledgable about fishkeeping and can give you sound advice.
im very sorry to say that there isnt much hope of your fish making it. if you want to euthanise him, you can take him out of the tank and put him into a plastic bag and into the freezer. he'll pass out quickly and die a peaceful death.
i dont like to euthanise fish until they wont swim up to eat anymore, and since you said your fish is active i know you wont want to put him down. if you need to though, at least now you know how,
to save him, youll need to take drastic measures and possibly spend a lot of money. first off, definitely get a bigger tank. treat the water and everything like you usually do. id also recommend adding some substrate (gravel is good) and planting a few plants to keep your ammonia down and make your fish feel safer. also, definitely buy a testing kit and test your water very often. ammonia, nitrates and nitrites should be at 0, and PH should be 7 or a little lower than that. because your water is hard, you should see what you can do to make it soft. balancing GH is very tricky and requires a lot of work, and youll need to buy a GH testing kit, but if youre willing to do that then make sure youre very meticulous. if your tank doesnt have a built in filter, then get one. make sure your temperature on your heater is in the high 20s (celsius). after everythings set up and youve made sure your parameters are good, move your betta in. continue the salt baths for your popeye, if it isnt going down then you can buy antibiotics (theyre expensive though). the swollen stomach is either constipation (which can be cured with fasting and then feeding peas) or dropsy (not much you can do afaik).
at the end of the day, you have to accept that your fish might die anyway. if you dont want to or cant put in all the money and time to try and fix him, you might want to consider putting him down.
good luck with everything. bettas are hardy little buggers, hopefully your little guy will pull through.
