There are various tests which are done by an eye doctor in order to check different eyesight conditions. Knowing about the common ones would help you to understand what is going on, the next time you pay a visit to the optometrist.
So, here is the list of common tests done for the eyes:
1. Visual Acuity Test
This is the most common and basic eye test and if you have ever paid a visit to any optometrist clinic, then it is very likely that you have gone through this. Closing one eye at a time, you’ll be given to read alphabets from a board that is positioned at a distance. The board have alphabets of different sizes and you optometrist would ask you about them, depending on your answer, he or she would be able to determine the level of your eye’s vision associating to the normal 20/20 one.
2. Retinoscopy
A retinoscopy helps the optometrist in understanding the prescription which would give you the best lens. The doctor would ask you to look straight through phoropter, while he or she would change lenses of the phoropter that has been placed on your eye. You would be asked to emphasize on the object which is situated in front of you while the optometrist would focus light on your eye in order to see how they react.
3. Refraction Test
If you are having a problem with visualization, then refraction test is a must for you. All you would need to do here is look through the phoropter to the eye chart that is situated at the opposite wall of the room.
Throughout the test, you would give different combinations of lens pair. The optometrist would constantly ask you to choose that definite pair of lenses which gives you the clearest vision. This eye test may also conclude with the fact that you would not need any vision correction prescriptions.
4. Keratometry Test
This eye test helps in measuring the curves and shape of the outside of the eye which is known as the cornea. The shape of the cornea is very important in determining your observation of the light and how your eyes reflect them. If an individual has a cornea that are elongated curves or vertical, then it would mean that the person is suffering from astigmatism and the keratometry test helps in determining this.
5. Peripheral Visual Field Test
It is a known fact that even though we look at something that we focus on, but we can also see the surroundings which come under the field of our vision. This area of vision, where you do not look upon directly is known as the peripheral vision and the visual field tests would help us to assess the same.
6. Intraocular Pressure Measurement
Forces and pressures are created by the fluids which are present inside our eyes and intraocular pressure measurement helps the doctor in testing that. An individual who has been deviated from the standard fluid pressure of the eyes is very much prone to glaucoma.
During these tests, you don’t t feel any pain or stress you just need to sit and relax. In case you face any problem with your eyesight, make sure to visit your optometrist so that they can conduct the eye tests and improve your vision.
