I'm sorry to hear about your accident.

Rest is important. Also, it is very common for people to have one, two or many different eye glass prescriptions following a brian injury.

As your brain recovers, your vision should improve.

After rest, warning signs, however, include: blurred vision, double vision, headaches when reading, losing one's place (skipped lines) when reading, a sense of going "cross eyed", etc. These warrant a look by a neuro-opthalmologist.

Best of luck- and yes, rest means almost doing nothing!
