These advanced technology lenses offer a number of benefits over conventionally surfaced lenses. Unlike conventional lenses, HD lenses are manufactured using digital computer technology and diamond-cutting tools that allow the lenses' surface to be customized to an individual's eyes.

HD glasses are a significant advancement in the world of eye health, but they are not miraculous. They are high-quality glasses that can often provide crisp vision. If your eye health is poor, they will generally not help you much more than a pair of conventional prescription glasses would.

Polycarbonate lenses are the most durable and impact-resistant lenses we offer, and they come with a 100% UV-protective coating. If you are looking for glasses for children, or tend to spend your time outside, we strongly recommend polycarbonate lenses.

HD glasses give you the best vision possible. The result is you see every detail the way it's meant to be seen - with increased clarity, vivid colors, and, defined details. While HD lenses are a great option for single vision prescriptions (nearsighted or farsighted), they do even more for progressive lens wearers.

Look for construction qualities such as smooth transitions from temple to frame front, and finely finished areas around the hinges. The surface quality of the acetate should be consistent and free from waves, pits or unsightly grooves.

Unlike conventional lenses, HD lenses are manufactured using digital computer technology and diamond-cutting tools that allow the lenses' surface to be customized to an individual's eyes. The quality of a high definition lens is similar to the quality of a digital camera.

The most expensive lenses for glasses are typically high-index, progressive, and polarized lenses. High-index lenses are made from special materials that allow for thinner and lighter lenses, which can be more expensive.

Vision impairment has a significant impact on the length 1 and quality of life (QoL). Previous research has shown that vision impairment is associated with an increased risk of falls, hip fractures, depression, social isolation, greater need for community services and greater risk of admission to nursing homes.

The Snellen Chart for Vision Testing Someone with perfect vision (20/20) would be able to see the same line of letter from 20 feet away that a normal person sees at 20 feet away. However, someone with 20/40 vision sees at 20 feet away what a normal person sees at 40 feet away.
