There are many options of frames, lenses, and coatings you can choose for prescription eyeglasses. Understanding the major options helps simplify the process of finding the perfect glasses.
What are glasses lenses made of?
Historically, prescription eyeglass lenses were made of glass. However, glass lenses are heavy and much more prone to damage, so they are now less commonly in use. Today most manufacturers make prescription glasses lenses out of plastic, which has lower cost, lighter weight, and increase in durability.
- Bifocals: prescription eyeglasses offering two prescription strengths in each lens.
- Top of lens: corrects for near-sightedness.
- Bottom of lens: corrects for far-sightedness.
- Trifocals: prescription eyeglasses offering three prescription strengths in each lens.
- Offer a third prescription strength to see items at medium distance or for a specific purpose, such as a wider viewing angle.
- Progressive Lenses: corrects for close, medium, and far distance viewing.
- Uses gradual prescription transition within a single lens, instead of the prescription change of bifocals or trifocals.
- Transition Lenses: change from clear to dark (sunglasses) in sunlight, replacing the need for separate sunglasses.
- Safety Lenses: the toughest, most damage-resistant lenses, best for sports, young children, or physically intensive work.
- Hi-Index Lenses: advance plastic lens, thinner and lighter than ordinary plastic lenses, allow for stronger prescription strengths than ordinary lenses.
- Polarized Lenses: reduce UV exposure to eyes and decrease glare, for people whose vision is sensitive to light.
- Anti-Reflective Coating: eliminates reflections and glares from both sides of the glasses lens.
- Lights has less halo (or large white circle) effect to the wearer.
- Observer looking at the glasses wearer won’t see reflections of room lights in the wearer’s glasses.
- Scratch-Resistant Coating: will greatly reduce the incidence of damage due to drops and dings.
- UV Protection Coating: significantly reduces UV light, as excessive eye exposure to UV light contributes to eye conditions.
- Blue Light Coating: reduces eye-strain due to blue light from digital screens, smartphones, computers, televisions, and tablets.
