Yes. When your high beams run the risk of blinding oncoming traffic you must dim them. The exact distance will vary with how powerful your beams are, and the alignment of the cars. If you're on the outside face of a curve you can keep them on a little longer.
In Texas, per 9-1 of the Texas Drivers Handbook, you should lower (dim) your headlights when you are: 1) Within 500 feet of an approaching vehicle. 3) When driving on lighted roads. 4) When driving in fog, heavy rain, sleet, snow, or dust.
1000 ft
At night a driver should dim his headlights when an oncoming motor vehicle comes within 1,000 feet. You should switch your headlights from full beam to dipped beam when a oncoming car passes. It is unsafe to leave your headlights on full beam as it blinds the driver of the oncoming car.

There are adjusting screws on the top and side of each headlight. I like to get on a really dark road at night and set them to how I like them without blinding oncoming drivers.
Driving with headlights on during the day reduces your chance of collision by about 25% because other drivers can see you from at least 1/2 mile ahead.
A headlight leveling system adjusts the vertical aim of the headlights based on the position of the rear suspension. As you load the trunk of a car, bed of a truck, etc. the suspension is compressed to allow the vehicle to ride smoothly. This causes traditional headlights to aim higher. A headlight leveling system lowers the headlight beam to compensate for this allowing the driver to see the road clearly without blinding oncoming traffic.
If you can see the oncoming vehicle then he can see you. Dim your lights at that time.
Within 500 feet of oncoming traffic.
when there are oncoming cars, it is appropriate to dim your headlights when they are about 300ft away. Check your diver manual for the most correct answer.
It is safe to use the bright [highbeam] headlights when there is no oncoming traffic/drivers who could be blinded by the bright light. Also, it is unsafe to use highbeams when there is fog or smoke which would reflect the light back to you, thus reducing the distance which you can see.
There are adjusting screws on the top and side of each headlight. You can aim them using a wall or your garage door to check level and projection and take it on the road to check whether you are blinding oncoming drivers. Driver side headlight should be aimed slightly to right to avoid that problem. If you live in a state with vehicle inspections, the inspection stations should have a device to check your headlights' aim.
