You can't accurately test your own eye power at home. Eye power, also known as refractive error, refers to how well your eyes focus light. It's measured by an eye care professional using specialized equipment.
Here's why you need a professional:
- Accurate Measurement: Eye power is measured in diopters, and a slight difference can significantly affect your vision. Specialized equipment like a phoropter and retinoscope are needed to accurately measure your eye power.
- Identifying Underlying Issues: A comprehensive eye exam can detect other eye conditions like astigmatism, presbyopia, or glaucoma that may require further attention.
- Personalized Recommendations: Your eye care professional can recommend the best corrective lenses (glasses or contact lenses) based on your specific eye power and needs.
To get your eye power tested, you should schedule an appointment with an optometrist or ophthalmologist.
