Eyesight plays a crucial role in your day-to-day life; it is necessary that you maintain your eye health in order to prevent vision problems. The best way to start with is by taking eye tests here are...
some of the basic tests to expect in your next visit to the optometrist.
1. Visual Acuity Test
This is the most common and basic Eyes Test that is performed when you first visit the eye doctor. This test is mainly conducted to measure the sharpness of your sight. You will be asked to use one eye at a time and a read few letters on the signboard from a specific distance.
2. Retinoscopy
This is the type of test where you will be asked to look into the thick instrument with several dials and lenses. It is mainly taken to identify the strength of the lens you will require. The equipment used is referred to as a phoropter and it is used by the doctor to conduct the test called retinoscopy.
3. Refraction Test
Along with retinoscopy, the refraction eyes test also helps in determining the type of eyeglass you will require. In the test, you will be asked to see into the phoropter and look at different characters at the eye chart located just to your opponent on the wall.
4. Keratometry Test
This is the eyes test that is performed to measure the shape of the cornea. The shape of the cornea affects how the light perceives and reflects the light. Some of the patients have elongated or steep curves in the cornea which leads to a condition referred to as astigmatism.
5. Intraocular Pressure Measurement
The intraocular pressure eyes test helps in measuring the force and pressure created by the eye fluid. An abnormal level of pressure in the eyes can prove to be a warning sign of glaucoma. The equipment that is used for testing glaucoma sends a puff of air to the open eyes.
