How is blindness detected?

Blindness is typically detected through a comprehensive eye examination conducted by an eye care professional. Key tests include visual acuity tests, which assess the clarity of vision, and peripheral vision tests to evaluate the field of vision. Additionally, doctors may use tools like tonometers to measure intraocular pressure and fundus cameras to examine the retina. If visual impairments are identified, further diagnostic tests can determine the underlying cause and extent of the blindness.
