Mullins Vision Associates deals primarily with Zeiss laboratories (www.zeiss.com) due to their technology and quality of ophthalmic lenses. Our office also uses other qualified manufacturers of ophthalmic products.
There are many different types of lenses, materials, lens coatings, and tints to enhance comfort, protection, and reduce glare. Our doctors will recommend what they believe is the best combination for your viewing demands. Our doctors routinely prescribe polycarbonate lenses for children and those who engage in activities that require a material that will not splinter upon impact.
Many of our patients wear no-line bifocals (progressive lenses). Our most popular progressive lens is the GT2-3D by Zeiss. This lens offers a wide distortion-free distance zone and ergonomically designed intermediate and near zones for clear vision and comfortable wear.
- Plastic: Conventional plastic is often used in spectacle prescriptions. It provides adequate visual quality and is lighter weight than traditional glass lenses. Plastic lenses can be tinted to almost any color or density of color. Plastic lenses can be scratched but can have an optional scratch protection applied.
- Polycarbonate: This is one of the most impact resistant lens materials available today. It is the choice for children and active adults. These lenses absorb UV light and can be made thin because of their unique strength. This lens material is often used for drill- mounted frames.
- Trivex: This material is similar to polycarbonate, but thinner and denser. The optics of this lens are superior to polycarbonate. This lens is also used often in drill-mounted frames.
- Single Vision: These lenses function as all-purpose lenses for persons who have normal accommodation. Persons who normally wear bifocals, trifocals, or progressive lenses can use single vision lenses for distance or near (Readers). Single vision lenses are available in all materials.
- Aspheric Lenses: These lenses provide special visual and cosmetic benefits for strong corrections and increases edge-to-edge clarity. These lenses greatly enhance the appearance of finished eyewear. These lenses are often made of high-index material.
- Flat-Top Bifocal: These are traditional type bifocal lenses with a line separating distance and near vision. The bifocal portion can be made in a variety of sizes, shapes, and powers.
- Trifocals: This lens design is similar to the traditional bifocal with another segment between the distance and near portion. This intermediate portion is meant to clarify images at arm's length.
- Progressive Multifocal (No-line Bifocal): These are the most popular bifocal design today. Progressive lenses offer continuous clear vision at all distances. Progressive lenses also have a cosmetic advantage due to the fact that they appear the same as a single vision lens. These lenses never reveal that the wearer is using bifocals. The transition between the distance, intermediate, and near is smooth and invisible.
- Computer Lenses: The human vision system is not designed for long hours of computer viewing. The typical symptoms of computer user are eyestrain, headaches, slow focusing, tired eyes, red eyes, and neck and shoulder pain. Computer lenses allow you to see everything within your computer workspace clearly. These lenses are also appropriate for artists, musicians, and craft workers.
- Office and Business Lenses: These lenses allow clear vision out to approximately ten feet. This feature allows the user to see beyond the computer and walk around the room easier.
- Anti-Reflective Coating: These coatings are much like those used on camera lenses. They reduce the amount of glare and improve the quality of light that is transmitted through the lens itself. These coatings are effective at reducing eye fatigue for computer users and anyone driving at night or working under fluorescent lighting. AR coatings also improve the cosmesis of lenses by removing distracting reflections.
- UV Protection: Ultraviolet rays from the sun are potentially harmful to your eyes. Special treatments are available to block these harmful rays. Polycarbonate and high-index materials already have this UV blocking agent.
- Scratch Coating: Plastic lenses are much more easily scratched than glass lenses. Special coatings have been developed to help protect your lenses from normal scratching. The modest cost for this protection is a good investment in your lenses.
