Which lens options are appropriate for hyperopic visually impaired patients?

• A. Glass lenses with no UV protection
• B. Plastic lenses with varifocal coating
• C. Polycarbonate, Trivex, Hi-Index, Aspheric, Lenticular/Full Field, UV protection
• D. Only standard CR-39 without UV

Answer: (D)

Hyperopic visually impaired patients benefit from lenses that are lightweight, thinner at higher powers, and provide good optical quality along with UV protection. Materials like polycarbonate and Trivex are known for being lightweight and impact-resistant, while high-index plastics let you achieve thinner lenses for stronger hyperopic prescriptions. An aspheric design reduces peripheral distortion and helps keep thickness down, and lenticular or full-field designs manage how lens thickness distributes across the surface. When you combine these features, you get a safer, more comfortable, and visually efficient pair of lenses, which is why a set of options including polycarbonate, Trivex, hi-index, aspheric, lenticular/full-field, and UV protection is the best fit for hyperopic visually impaired patients. In contrast, glass lenses with no UV protection are heavy and offer no UV safety; plastic lenses with a varifocal coating don’t necessarily address thickness or UV protection; and standard CR-39 without UV protection lacks the thinness benefits and UV safety needed for higher hyperopic powers.
