If your optometrist discovers you have a refractive error following an eye exam, you will be prescribed lenses to accommodate your particular vision problem. We provide a wide variety of lenses made from state-of-the-art materials using the latest ophthalmological technologies to support eye health and give you clear, crisp vision. Popular eyeglass lens options include single vision, multifocal/progressive, trifocal and bifocal lenses. To enhance the performance of your lenses, Sevigny & Associates Eye Care also offers lens coatings to protect your eyes from harmful UV rays, reduce glare and prevent scratching.
For people with astigmatism, farsightedness or nearsightedness, single vision lenses improve vision clarity by extending one type of focal power over the entire lens. This is the most prescribed lens for people under 40 who do not have presbyopia.
If you have a refractive error and presbyopia, your optometrist may prescribe bifocal lenses to improve your vision. Presbyopia is an age-related condition affecting the ability of your eye's lens to contract and expand efficiently enough to focus on objects up close. Bifocals contain two prescriptions--one for your refractive error and one to correct presbyopia. The top half of a bifocal lens corrects nearsightedness or farsightedness while the bottom half corrects presbyopia.
Trifocal eyeglass lenses have three different prescriptions. The bottom prescription improves near vision, the middle prescription improves your ability to see things within an intermediate distance and the top prescription is for clarifying distant vision. Especially helpful for people with presbyopia and reduced depth of focus, trifocal lenses significantly improve your ability to see the print on a computer screen or items on our vehicle's instrument panel.
Trifocal and bifocal lenses are just forms of multi-focal eyeglass lenses that provide multiple prescriptions without demarcation by a visible line. People who do not want bifocal or trifocal lenses with visible lines can choose to wear progressive lenses.
Darkening upon exposure to UV radiation, photochromic lenses allow people to transition from indoor lighting to outdoor lighting without wearing a separate pair of sunglasses. Once you return to indoor lighting, photochromic lenses return to their original, clear state.
