Refractive error is very common among children and middle-aged patients. In case of eyesight problem, first, consult an eye surgeon. He will check your vision and refractive error with autorefractor. Cycloplegic refraction is a must for the first time refractive error checkup.

Refractive Error Checkup:

  • You will be advised to sit for half an hour outside the consulting room after giving you cycloplegic eye drops. Then, you will be examined for dilated pupil refraction. This will perfectly give your refraction.
  • Then, your doctor will check for vision at the same time or some will call you one or two days later for perfect numbers. However, this will give you perfect numbers.

This is very useful for all age groups of patients. After cycloplegic eye drops administration, you will be having some blurred vision for distance and more for near. But, do not worry as this will go away in a day.

Also, those who are near 40 years of age and have difficulty with near vision, should start wearing presbyopic glasses. Without this, you may increase your headache by reading without glasses. Those who work for a long time on computers around 7 to 8 hours also should use artificial eye drops between the work and use antireflective coating glasses for computer use.

Refractive errors may be plus (hypermetropia - long-sightedness), minus (myopia - short-sightedness) or astigmatism (corneal curvature problem) numbers. Some people ask about other methods used to remove the numbers, but this is not true. Numbers are natural phenomena and not removed by medicine or other way. It can go away by its own depending upon the type of numbers.

When you go for number checking please tell the doctor about your eye problem completely.
