FIrst of all uncorrected vision is not at all helpful. A healthy eye that has myopia may have 20/200 vision at distance uncorrected. With proper glasses it may be 20/20.
You must be about 64 years old. It's not likely that the change in vision is due to your injury at age 18. More likely you have cataracts, the Fuchs has gotten worse, you may have macular degeneration, glaucoma or you could simply need better glasses. Discuss this with your ophthalmologist.

Deterioration of vision comes naturally as we age, maybe that accident of yours contributed to your eye problems today.
