You check your vision by undergoing an eye examination, during which a professional assesses your visual acuity.
Understanding Vision Checks
Vision checks are crucial for maintaining good eye health and ensuring you have the clearest possible vision. These checks typically involve a series of tests and assessments conducted by an optometrist or ophthalmologist.
The Eye Exam Process
The typical process for checking your vision is as follows:
- Initial Consultation:
- Your doctor will start by asking about your medical history, including any existing eye conditions.
- Vision Assessment:
- You will be asked to look through a phoropter, an instrument that is placed comfortably in front of your eyes as you sit in the examination chair.
- As you look through the phoropter, you will be asked to identify letters on a chart approximately 20 feet away. This chart test helps determine your visual acuity.
- The phoropter has lenses that can be changed. This allows the doctor to find the correction that gives you the sharpest vision.
- Additional Tests:
- The eye professional may perform other tests such as:
- A retinal exam
- Tests for color blindness
- A test to measure eye pressure
- A test of visual field

Importance of Regular Checks
Regular vision checks are essential for several reasons:
- Early Detection of Issues: Eye exams can detect early signs of eye diseases, like glaucoma and macular degeneration, which can be more easily treated when found early.
- Updating Prescriptions: Vision can change over time, so regular checkups are important for getting accurate prescriptions for eyeglasses or contact lenses.
- Overall Health Check: Sometimes changes in vision can indicate other health issues.
Where to Get Your Vision Checked
- Optometrist: These professionals specialize in vision care, including eye examinations and prescribing eyeglasses and contact lenses.
- Ophthalmologist: These are medical doctors who can provide complete eye care, including surgery.
- Vision Centers: Some optical stores have eye care professionals on staff.
In summary, having your vision checked involves an eye exam, during which you'll use a phoropter to view a chart. Consistent eye exams are vital for your eye and overall health.
