I'm sorry to hear about your eye injury.
I just prayed for you and found three articles that might have helpful information.
One applies to eye injuries from abrasions rather than sun over exposure, but has 6 suggestions near the end that may be good for sunlight injuries too.
It mentioned wearing sunglasses. I'm not an eye doctor, but if I used glasses, I would choose those only with 100% UV protection.
Here's that article.

The next 2 articles contain a list of supplements and foods that are often taken for eye health. I have used some of these myself and think they were helpful for helping my own eye injury to heal.

The Lord loves you and
I pray that He heals you quickly .
The last one I will share is a Bible message that someone shared with me one day.
May it be a blessing to you too.
Blessing from Heaven
To your health and happiness
