You need a prescription for corrective lenses because an optometrist must check your vision. You can use your own prescription or let the retailer get it from your optometrist. If you want glasses for style or reading, you can get non-prescription glasses without needing a prescription.
When buying glass lenses, consider the type of lenses you need. Options include single vision for nearby or distant sight, bifocal for both distances, and progressive lenses for a smooth transition between distances. Another essential factor is the lens material. High-index lenses are thinner and lighter, while polycarbonate lenses offer impact resistance. Additionally, consider lens coatings. Anti-reflective coating reduces glare, while scratch-resistant coating enhances durability.
In summary, you need a prescription for glass lenses to ensure correct vision correction. Knowledge of lens types and materials aids in making informed choices.
Understanding the significance of your prescription guarantees you receive the right lenses for your vision needs. Next, we will discuss how to interpret your prescription and what to look for when selecting your glass lenses.
