Put simply, changing the physical shape of the lens by pumping the silicone fluid in or out alters its refractive power – the extent to which a lens bends light as it passes through the eye – allowing the wearer to correct their own refractive error.

A Light Adjustable Lens™ (or LAL) is a specialized type of intraocular lens used in cataract surgeries to correct vision problems. Unlike traditional intraocular lenses which are made of a fixed material, the LAL has the ability to be adjusted after the initial surgery.

In short, single vision lenses are glasses lenses that only offer ONE type of vision correction. This means that they are crafted to help people see better at farther or shorter distances (nearsighted or farsightedness), but never both.

Progressive lenses are much like other multifocal glasses, except they have a smooth transition between different lens corrections. Instead of a line, your progressive glasses will look like they have single-vision lenses. This detail means your glasses will look more attractive and stylish.

Light Adjustable Intraocular lens (LAL) allows post operative titrations in intraocular lens (IOL) power after the eye has healed and secured refractive stability post cataract surgery, facilitating customization and optimization of lens to achieve the desired vision .

You'll Experience a Better Quality of Vision Light Adjustable Lenses provide patients with the best possible sight, shorter treatment duration, and less downtime. With the Light Adjustable Lens, you can start making modifications only a few weeks after cataract surgery.

The Light Adjustable Lens is made of a special photosensitive material that changes the power of the implanted lens in response to ultraviolet (UV) light, increasing the likelihood of a successful outcome. The cataract removal and intraocular lens implantation procedure is equivalent to traditional cataract surgery.

What are the different types of eyeglass lenses?

• Concave lenses. These are thinnest in the center.
• Convex lenses. These lenses are thickest in the center, like a magnifying glass.
• Cylindrical lenses. These curve more in one direction than in the other.

A single vision lens is a mono visual lens yielding a single field of vision; whether there is no prescription or a single RX prescription. The three forms of single vision lenses are plano, concave (minus prescriptions) and convex (plus prescriptions).

Progressive lenses are perfect for nearsightedness and farsightedness, but there's a learning curve and some people never adjust to these lenses. To help your eyes adjust, wear your progressive lens as often as possible in the beginning.

Progressive lenses are used to correct presbyopia, the loss of the eyes' ability to focus on near objects. Sometimes referred to as no-line bifocals, progressive lenses have three visual fields for viewing distant objects, intermediate objects, and close-up objects.

The Light Adjustable Lens (LAL) is the only IOL that enables you and your doctor to design, trial, and customize your vision after cataract surgery. Adjustability takes cataract surgery to the next level by giving you a lens customized specifically for your eyes.

Lenses that protect your eyes: Anti-glare lenses protect your eyes against bright lights and are great for people who drive regularly or for those who spend some time outdoors. Blue light protection lenses filters harmful light that comes from the sun, televisions, computer screens and cell phones.
