Amid an eye exam, the specialist will gather a patient's medicinal history and check a few variables, including visual keenness (sharpness of vision dependent on how well the patient can peruse an eye outline). Following on a thorough eye exam, the specialist can exhort you on how frequently to have your eyes checked.

Like clockwork starting at age 40, on the off chance that you don't have any hazard factors
At regular intervals in case you're over age 65 or at high hazard (6)

Amid your visit, the eye specialist may play out various distinctive systems, including:
Glaucoma Examination
Your specialist will utilize unique eye drops to enlarge your understudies, which enables all the more light to enter the eye and makes it simpler for the specialist to look at the back of your eye.

Glaucoma Tonometry Test
This test estimates the weight inside your eye. It's easy and causes insignificant distress.
The most exact types of the test measure the power expected to quickly straighten a zone of your cornea (clear layer at the front of the eye).
To begin with, your specialist will utilize eye drops to numb the surface of your eye and apply an orange color to incidentally recolor the eye.

High eye weight is a hazard factor for glaucoma. Individuals with thin corneas may have incorrectly low IOP readings, while individuals with thick corneas may demonstrate a higher-than-genuine IOP. (11)
Perimetry
Otherwise called a visual field test, this method estimates the extent of focal and fringe vision and distinguishes vulnerable sides.
