The primary objective here is to determine whether you are experiencing hyperopia farsightedness, myopia nearsightedness, astigmatism, or presbyopia, which affects your ability to see close objects clearly.
To get the precise prescription, several measurements are taken:
Visual Acuity: This test determines how well you can read letters at different distances from a standard chart, measuring the smallest letters you can accurately identify.
Refraction Test: A shines light into each eye and measures the curvature of your cornea and lens to determine your vision problems. s are used to calculate the required eyeglass prescription.
Pupil Size and Alignment: This test confirms that both eyes work together efficiently, preventing double vision issues caused by misalignment or irregular pupil size.
After the initial examination, if it is determined that you need glasses, measurements of the eye's distance from the cornea front-to-back measurement are needed to determine the correct lens thickness for your glasses. This is commonly known as 'pupil distance' and must be accurately measured.
