Hi-index and UV protection options are more accessible to hyperopic than emmetropic eyes?

• A. Hi-index and UV protection
• B. Polycarbonate and trivex are not available to hyperopic
• C. No difference
• D. They cannot use tinted lenses

Answer: (A)

The idea being tested is how prescription strength influences the lens materials and features that are most beneficial. When a person has hyperopia, the lenses needed to correct that farsightedness are powered positively and tend to be thicker and heavier, especially at higher powers. Using high-index lens materials reduces that thickness and weight, making the glasses more comfortable and aesthetically pleasing. UV protection is a desirable feature that many modern lenses provide, and it’s particularly valued for anyone who wears lenses regularly, including those with higher prescriptions, because protection comes with the lens itself rather than requiring a separate add-on. So, hi-index materials and UV protection are the features that are especially advantageous for hyperopic wearers, which is why this option is the best choice. The other statements aren’t accurate: polycarbonate and trivex are indeed available for hyperopic eyes and are often used for thin, light lenses; there isn’t a universal “no difference” between hyperopic and emmetropic eyes in terms of access to these options, since hyperopes typically benefit more from thickness-reducing materials; and tinted lenses can be used by people regardless of their refractive status.
