Options for glasses
When choosing glasses, you’ll notice that there are several options for lens, including materials and coatings. These extra choices aren’t just about appearance—they can make a real difference in comfort, durability, and how well your glasses work for your lifestyle.
Lens types
- Single Vision Lenses: These are designed to correct vision at one distance—either near or far. If you only need help with close-up tasks, like reading or using a computer, single vision lenses are a great option.
- Bifocal/Progressive Lenses: These help with both near and far vision in one pair of glasses. The top part of the lens helps you see things far away, while the bottom part helps with close-up tasks, like reading.
Lens materials
- Plastic (CR-39): Lightweight and affordable option for people with mild to moderate prescriptions. However, plastic lenses can be a bit thicker than other materials for higher prescriptions.
- Polycarbonate: Durable option that is impact-resistant, making them a good choice for people with active lifestyles, especially children.
- High-Index: Thinner and lighter lenses that are great for those with higher prescriptions who want to avoid the bulk of thicker lenses.
Lens coating
- Anti-Reflective (AR) Coating: Reduces reflections on the lens from glaring bright lights or screens, helping prevent unwanted eye strain.
- Scratch-Resistant Coating: Helps protect your lenses from everyday wear and tear, like when you accidentally drop them or forget to put them in a case. They help prolong the life of your lenses and prevent distracting scratches.
Other Add-ons
- Blue Light Filter: If you spend a lot of time in front of a computer, tablet, or phone, blue light filtering lenses may be recommended by your optician.
- UV Protection: Just like sunscreen protects your skin from harmful UV rays, some lenses offer UV protection to keep your eyes safe from the sun’s rays.
