A pre-evaluation for an eye check involves several key tests to assess overall eye health and detect any vision issues:
1. Auto Refraction: This test uses an automated device to estimate your refractive error, which helps determine the correct prescription for glasses or contact lenses. It assesses for myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
2. Intraocular Pressure (IOP): This test measures the pressure inside your eye. Elevated IOP can be a sign of glaucoma, a condition that can lead to vision loss if not treated.
3. Visual Acuity (VA): This test measures how well you can see at various distances using an eye chart. It determines if you have normal vision or if you are nearsighted, farsighted, or have astigmatism.
These evaluations are crucial for diagnosing eye conditions early and ensuring appropriate treatment to maintain or improve vision. Regular eye checks are recommended for everyone, especially those with a family history of eye diseases or individuals over 40 years old.
