Popeye. Caused by poor water quality and/or injury. The only treatments are either doing daily 75% water changes and vacuuming your substrate or one heaped tablespoon of aquarium salt, rock salt or swimming pool salt per 20 liters (5 gallons) of water and leaving the salt there for no more than two weeks. Could you tell me me tour weekly routine when cleaning the tank? Size of the tank? Water parameters?
I don’t know my water parameters how would I get them? but there is 10 fish in there 3 platys and 7 mollys. it is a 54 litre tank which is kept at 26°c constantly (I’ll add a photo) . 2 of the other mollys chase her around quite a lot and don’t leave her alone we’ve noticed injury’s to her top fin before which I thought was due to the other fish picking at her but we didn’t have anywhere to separate them. We change the water every Sunday but probably only change 50-75% depending on how dirty the tank is. We have had 25 fry born in the tank this week So the sand has been moved when catching the fry causing the water to go cloudy

Test strips or API Master Test Kit, it can be pricey, btu its really worth it.
Your tank is really overstocked and the tank is too small for mollies and they need a 30 gallon tank. If other fish are chasing her, it might be the cause of popeye as she/he might have bumped in a decor and the infection have started. Did you cycle the tank? What are the water parameters, like ammonia, nitrite and nitrate? What are the dimensions of the tank?
Maidenhead Aquatics where we got the fish from said that’s what size tank we needed for that many fish and 2 males were chasing her I’ve seen her swim into the heater once or twice and I don’t know the water parameters ive just ordered some test strips from amazon to come tomorrow

Never get any help from stores selling fish as they often don't know what they say. Either return all the mollies or get a 30 gallon tank for atleast 4 mollies and all of your platies.
The only way to test the water is to buy the water test kits that’s mean you have to buy 3 test kit; Ammonia, Nitrite and Nitrate test
Cycle your tank
To get rid of Ammonia (NH3) and Nitrite (NO2-) completely, cycle a tank is when you put Ammonia and Nitrite down to 0 by using Nitrosomonas bacteria to "eat" Ammonia and turn them to Nitrite then another bacteria name Nitrobacter and Nitrospira will "eat" Nitrite and turn them to Nitrate (NO3-) you can speed up the process by buying the “bacteria bottle”.
Mollies and platy need bigger tank atleast 20 Gal, Pop eye cause by low water qualities and the best way to treat them is to do 75% daily water changes for 2 weeks (dont do 100% as it can kill fishes), substrate clean using syphon or aquarium vacuum, add salt; rock salt, swimming pool salt, aquarium salt at the dose rate of 2 table spoon per 20 litres of water.
Keep salt level like this for 2 weeks but no longer than 4 weeks as it can cause kidney damage.

Its popeye. A cure is to do daily water changes and salt treatment. However the last (and only) fish to have popeye I euthanized because I felt it was too cruel to try tot keep it alive when it was in pain
Do daily large water changes as was mentioned above.
