By keeping Ur eyes perpendicular to the vernier and main scale while taking the measurement.
Avoid Information overload while reading

If you are going to measure out a different solution, you must rinse and drain well to avoid contaminating one substance with another. If you are using the same solution, there is no need to rinse, and in fact it is better not to do so, because the rinsings will dilute the next batch.
Avoid eye contact.
By regular practice
You should position your eye directly in line with the scale or mark you are reading to avoid parallax error. This ensures that you are looking at the measurement or reading from a straight-on perspective, reducing any angle-induced errors.
To read a tuberculin syringe you simply have to look at the calibrations on the syringe. Make sure that your eye is level to avoid taking a wrong reading as a result of parallax.
When reading the volume of fluid in a graduated cylinder, the eye should be at the same level as the meniscus (the curve at the surface of the liquid). This helps to avoid parallax error and ensures an accurate reading of the volume.
The strip of mirror is mounted to help eliminate parallax errors when reading the value on the scale of the voltmeter. By aligning the needle's reflection with its actual position on the scale in the mirror, the observer can avoid viewing the needle from an angle, which could result in an inaccurate reading due to parallax. This setup ensures a more precise and accurate reading of the voltmeter.
There is no such way to avoid parallax error, you just have to be careful.. :)
To achieve accurate volume of NaOH during titration, you should use a calibrated burette to deliver the NaOH solution, ensure the meniscus of the liquid is at eye level when taking readings, and record the volume added precisely at the endpoint of the titration when the indicator changes color. Practice consistent technique and avoid parallax errors for accurate volume measurements.
That's great I have learned something new
To get an accurate liquid volume measurement, ensure the measuring container is on a level surface, read the measurement at eye level to avoid parallax errors, and use the appropriate measuring tools calibrated to the desired units.
To accurately measure the volume of a liquid using a graduated cylinder, make sure to read the meniscus at eye level to avoid parallax error. Pour the liquid slowly and carefully to prevent spills and ensure an accurate measurement. Always use the smallest graduated cylinder that can hold the volume of liquid you are measuring for increased accuracy.
Following are some precautions to be taken while measuring length with the help of a metre scale: Scale must be placed in contact with the object along its length. Eyes must be exactly perpendicular to the point where the measurement is to be taken, to avoid parallax error. If the ends of a scale are broken/damaged we should avoid taking measurements from the end. Instead, we should place the object on any other fully visible mark on the scale (say, on 2 cm instead of 0). Then you must subtract the reading on this mark from the reading at the other end.
Ensure that the measuring cylinder is on a flat surface to get an accurate measurement. Also, read the measurement at eye level to avoid parallax errors. Handle the measuring cylinder carefully to prevent breakage.
Parallax errors in a scale occur when the viewer's perspective causes the measurement to appear inaccurate. This can happen if the viewer's eye is not directly in line with the measurement marking, leading to erroneous readings. To avoid parallax errors, it is important to position the eye directly above the measurement scale when taking readings.
