When it comes to choosing eyeglass lenses, it’s no longer a simple choice of glass or plastic. Luckily, our staff of experienced opticians at Enterprise Optometry Group take the time to discuss how different prescription eyeglass lenses can impact your vision, answer any questions you might have, and supply you with the most up-to-date information in order to keep your eyes healthy. So if you know you need Redding CA eyeglasses lenses, but are unsure exactly what style or brand, we would be happy to educate you in the different types of lenses and what they do.
Nearly everyone can benefit from thinner, lighter lenses. High index lenses can be up to 50% thinner than regular glass or plastic lenses, and they’re usually much lighter, too. Though these lenses are especially beneficial if you have a strong eyeglasses prescription, they can make a noticeable difference in the appearance of virtually any pair of glasses. High index lenses bend light more efficiently than regular glass or plastic lenses, so less lens material is required to correct your vision. To make high index lenses even more attractive, most of them have an “aspheric” design. This means that instead of having a round curve on the front surface, these lenses have a curve that gradually changes from the center to the lens to the periphery. This makes aspheric lenses noticeably flatter for a slimmer, more attractive lens profile. Though aspheric lenses offer advantages for all prescriptions, they are particularly beneficial if you are farsighted. Aspheric lenses greatly reduce the magnified, “bug-eye” look caused by regular, highly curved lenses for farsightedness, and they greatly reduce the “bulge” of the lenses from the frame. Polycarbonate and Trivex lenses are special high index Redding CA eyeglass lenses that offer superior impact resistance. These lenses are up to 10 times more impact resistant than regular plastic lenses, making them an ideal choice for children’s eyewear, safety glasses, and for anyone with an active lifestyle who wants a thinner, lighter, safer lens. Photochromic lenses are convenient indoor-outdoor eyeglass lenses that automatically darken to a sunglass shade outside when exposed to sunlight, and then quickly return to a clear state indoors. These lenses also provide 100% protection from the sun’s UV rays, and are available in a wide variety of lens materials and designs, including bifocal and progressive lenses.
Most popular lens designs (single vision, bifocal, progressive, photochromic, etc.) come in high-index materials, and your doctor or optician will know which ones are available in your prescription. Bifocal and trifocal high index lenses are also available, though the selection is more limited. With so many new lens products available, it’s hard to know all your options and decide which lenses are best for you. Rely on our expertise to make selecting your Redding CA eyeglasses easy and fun. Our trained staff welcomes the opportunity to help you find the perfect eyewear for your personal style and vision requirements.
