Certified Ophthalmic Assistant Practice Exam

What two items are used to clean the retinoscopy lens, polarizing lens, red lens, and maddoc rod lens?

1. Cotton tip swab and glass cleaner

2. Microfiber cloth and soap

3. Alcohol wipes and tissue paper

4. Cotton ball and water

The correct answer is: Cotton tip swab and glass cleaner

The correct answer is A, cotton tip swab and glass cleaner. It is essential to use a gentle and non-abrasive cleaning method to ensure the longevity and clarity of specialized ophthalmic lenses. A cotton tip swab allows for precision in cleaning small lenses without scratching or damaging them. Glass cleaner is specifically formulated to provide streak-free cleaning without leaving residue, making it an ideal choice for maintaining the clarity of lenses used in retinoscopy, polarizing, red, and maddoc rod examinations. Options B, C, and D are not typically recommended for cleaning ophthalmic lenses. Microfiber cloths may not provide enough precision for cleaning small lenses, soap and water can leave residues that may affect the accuracy of the lenses, alcohol wipes can potentially damage specialized lens coatings, and cotton balls are not as precise as cotton tip swabs for cleaning small lenses.
