Devices prescribed to correct refractive errors include which of the following?

• A. Artificial Tears
• B. Glasses and Contact Lenses
• C. Vision Therapy
• D. Sunglasses

Answer: (B)

The correct choice highlights the use of glasses and contact lenses as primary devices for correcting refractive errors, which occur when the eye does not bend light correctly, leading to blurred vision. Glasses typically consist of lenses that are shaped to redirect light entering the eye, thus sharpening the focus on the retina. Contact lenses serve a similar purpose but are placed directly on the eye's surface, providing a wider field of vision and eliminating the potential distortions that can occur with glasses. Artificial tears are designed to alleviate dry eye symptoms rather than correct vision. Vision therapy is a type of rehabilitation focusing on improving visual skills but does not serve as a direct correction for refractive errors. Sunglasses mainly protect against harmful UV rays and provide comfort from glare, but they do not correct refractive errors. Thus, glasses and contact lenses are the only options from the list that directly address the need to adjust the focus of light entering the eye, making them essential tools for individuals with refractive errors.
