1. Visual Acuity Test:
- Place an eye chart about 20 feet (6 meters) away.
- Cover one eye with your hand or a patch and read the chart starting from the top.
- Note the smallest line you can read clearly.
- Repeat the process with the other eye.
2. Color Vision Test:
- Acquire a color vision plate, such as the Ishihara test or similar.
- Hold the plate at a comfortable viewing distance.
- Identify the numbers or symbols formed by the arrangement of colored dots.
3. Pupil Reflex Check:
- Stand in front of a mirror in a dimly lit room.
- Hold a flashlight or a small light source about 6-8 inches away from one of your eyes.
- Observe whether your pupil constricts (becomes smaller) when the light is shone into the eye.
- Repeat the same procedure with the other eye.
4. Eye Movement Test:
- Ask a friend or family member to help you with this test.
- Stand about 3-4 feet away from the person, ensuring they're at eye level with you.
- Hold your finger or a pen in front of your nose and slowly move it horizontally, vertically, and diagonally.
- Follow the movement with your eyes while keeping your head still.
5. General Observation:
- Take a close look at your eyes in a well-lit area.
- Check for any visible abnormalities like swelling, redness, or discharge.
- Examine your eyelids for any lumps, bumps, or inflammation.
It's important to remember that these self-checks serve as a general assessment and cannot replace a comprehensive eye examination. If you notice any issues during your self-assessment or have concerns about your vision, it's essential to consult an eye doctor or optometrist for proper evaluation and treatment.
