Dr. or ER can check: To be checked at the ER, one can call 911 for an ambulance. For dizziness or lightheaded feelings, a doctor's evaluation is needed. Urgency depends on the details. The doctor may run some tests, and may refer to others such as a cardiologist, ENT doctor, or neurologist. Symptoms may be from inner ear or balance organ problems, from mild dehydration, from some anemia, from heart problems, etc...

Vision loss. : Several things come to mind the most concerning is you having a stroke and you need to go to the emergency room now. It may not be a stroke but a migraine, brain issue( this includes ma, seizure. You should see a doctor.
