Welcome to FishLore!! So glad that you came here and are taking the extra time to do your research and find out how to do right by the little fish whose life depends on you.

So many people don't know any better, and keep sad fish.

So... kudos to you!
Laars looks like a lovely boy! Kind of a copper colour? I like the glass rocks you have in his tank, too.
One cure-all for most fish illnesses is garlic. My boys HATE garlic by itself (seems most people's bettas like it... go figure.) So, I soak their blood worms in a little garlic juice and water once a week. They only need it as a supplement unless they're sick, at which point it's best to feed them a little garlic each day.
I haven't heard of white spots on a
betta's eye, but it is possible that he has
ICH and you can only see the spots there because of his colouring... just a wild guess. Ich is a parasite with three life stages, and is best treated with garlic supplement, a water temp. of 83-84F, daily 50% water changes w/ gravel vacuuming each time, and low light. The increased temperature speeds up the parasite's life cycle, getting the cysts off your fish and into the water, gravel, and plants faster, where it will propagate if left alone. The purpose of cleaning the gravel and changing the water is to remove the parasites before they have a chance to return to your fish and spawn again (a highly simplified explanation, but really all you need.)

You should see vast improvements in just a week with this treatment. Even if it isn't ich... none of these things will harm your fish, which is why I recommend treating naturally rather than running out and buying one of those yucky chemical treatments.
Good luck!
