If cute doesn't matter that much, get yourself a pair of welding-grade safety glasses. I'm not blind, but due to my autism, I have issues with bright lights and my boyfriend gave me his pair of glasses that he said he bought for not that much at Home Depot or Lowes. I don't remember which. They're super dark, green-tinted, and what's more, they wrap around my face and don't let so much light in from the top and sides like regular sunglasses do. They're the most amazing invention, and I wish I'd known about them earlier. I've had them for about a year, and they've changed my life! I only wish I could get my prescription glasses like this so I don't have to take the toss-up between slightly blurry when driving or squinting so hard I get a headache from the bright sun.

Noir medical makes great sunglasses for specific eye conditions. Just got my pair and love it.

Look up glacier glasses. They have protective shields to block light from around the lenses. You can get them really dark because they are made to be used in very bright places. They are also available in all different shapes and sizes so you can probably find something that meets your cute requirements as well. They also look like normal glasses and probably won’t attract possibly unwanted attention like welding goggles or something would.

I have cocoons. They fit over my normal glasses. I wear them when working (software engineer) and whenever I'm outside. Cute they are not, but they work.

I am also severely photophobic as well. In sunlight all I can see is the color yellow. I use cocoon sunglasses.

They have multiple frame colors and the colors of the lenses outside are customizable too. I have ones that fully enclose my eyes bc of the glare from above and below can give me headaches.

They also have slim frame designs that don't make you look like a cartoon blind person in huge dark sunglasses. Which I appreciate.

I also have a super cheap pair from Amazon that I don't even know the brand of, and honestly I painted the inside of the lenses on that pair black just so I had something to block out the light.

Ask your doctor where to get glasses for people who have just had pupil dilation. Another option is try out wrap-around glasses for boating. They might not be as dark but they are designed to cut down glare a ton. Make sure your glasses are UV resistant and also polarized. You can also decorate whatever glasses you end up getting. Take a trip to the craft store and go crazy.
