Understanding Progressive Lenses: A Complete Guide

Progressive lenses work by gradually changing in power from the top of the lens to the bottom. This gradual change allows you to see clearly at all distances without having to switch between multiple pairs of glasses. The top portion of the lens is designed for distance vision, such as driving or watching television. The middle section is optimized for intermediate vision, which is ideal for computer work or viewing objects at arm's length. The bottom portion is designed for near vision tasks like reading or detailed close work.

This seamless progression of lens power mimics the natural vision experience more closely than traditional bifocals or trifocals, which have abrupt changes in prescription strength.

• Seamless Vision at All Distances: Progressive lenses provide clear vision at all distances without the need to switch between multiple pairs of glasses.

• Aesthetically Pleasing: Without visible lines on the lenses, progressive glasses have a more modern and youthful appearance.

• No Image Jump: The gradual change in prescription eliminates the jarring image jump that occurs when your eyes move across the line in bifocals.

• Natural Vision Experience: Progressive lenses more closely mimic the way your eyes naturally focus at different distances.

• Age-Appropriate Solution: As presbyopia (age-related farsightedness) progresses, progressive lenses can be adjusted to meet your changing vision needs.

It's important to note that there is typically an adaptation period when first wearing progressive lenses. Because of the way the lens power changes throughout the lens, new wearers may experience some peripheral distortion or a "swimming" sensation initially. Most people adapt to their progressive lenses within 1-2 weeks with consistent wear.

During this adaptation period, it's helpful to:

• Wear your new glasses consistently

• Point your nose toward what you want to see, rather than just moving your eyes

• Be mindful of the different viewing zones in your lenses

• Practice looking through the appropriate parts of the lens for different distances

Progressive lenses are ideal for people with presbyopia, a natural age-related change in vision that typically begins around age 40. Presbyopia makes it difficult to focus on close objects, such as reading material. Progressive lenses are also suitable for people who need correction for multiple vision issues and want the convenience of a single pair of glasses.

However, progressive lenses may not be the best choice for everyone. Some people may prefer the wider reading area provided by bifocals, or may have specific occupational needs that are better served by single vision or occupational progressive lenses.

Computer Progressives

Specifically designed for computer users, these lenses have a larger intermediate zone for viewing a computer screen and a smaller distance zone, as they're primarily intended for indoor use.

Proper fitting is crucial for successful progressive lens wear. This includes:

• Accurate measurement of pupillary distance (PD)

• Proper frame selection that's large enough to accommodate the different viewing zones

• Precise measurement of fitting height to ensure the near vision portion of the lens aligns with your natural reading position

• Frame adjustment to ensure the lenses sit at the correct angle and distance from your eyes

At Clarity Vision, our experienced opticians take detailed measurements and work with you to select the perfect frame and lens combination for your specific needs and lifestyle.

To maintain the clarity and longevity of your progressive lenses:

• Clean them regularly with a microfiber cloth and lens cleaner

• Avoid placing your glasses face-down on surfaces

• Store them in a protective case when not in use

• Avoid extreme heat, which can damage lens coatings

• Have your glasses professionally adjusted if they become misaligned
