Blurred Vision and Near Vision Eyestrain?
Traditional bifocal glasses and even older generation progressive (no line bifocal) lenses can fall woefully short when it comes to helping us see small screens on our smartphones or GPS devices, and to see our large computer monitors clearly from side to side.
The challenges of the computer screen have increased as screens have gotten wider and with the variety of positions where computer monitors can be located.
“The information age has taken a toll on our eyesight,” says Jeffrey Anshel, an optometrist in Carlsbad, Calif., and president of Corporate Vision Consulting, which advises employers on vision issues.
More people are showing up at eye appointments complaining of headaches, fatigue, blurred vision and neck pain—all symptoms of computer-vision syndrome (CVS), which affects some 90% of the people who spent three hours or more at day at a computer, according to the National Institute of Occupational Safety and Health.
Advanced Eye Examination
The good news is that with a little detective work and a careful eye examination we can create customized solution to solve these problems.
By taking a moment to measure the distance from the bridge of your nose to your computer screen, keyboard and the papers on your desk you can really help your doctor deliver the vision that meets your needs.
“At Spectrum Eyecare, we have a philosophy that allows us to take more time with the patient, so we can truly understand their vision needs and recommend customized eyeglass and/or contact lenses that best balance the demands of near, intermediate and distance vision”, says Cassie Salisbury who is the lead optician at Spectrum Eyecare.
Advanced Eyeglasses Lenses
Furthermore, the new generation of customized HD progressive lenses provides a much wider intermediate and near vision focal area that greatly enhances the value of these lenses in the digital age. In the past year further advances in HD progressive lenses allow for the design to be further optimized for near performance.
When evaluating your vision options, choosing the least expensive progressive is usually a mistake. Older progressive lenses were shown to be much less satisfactory to patients in a recent study published by UC Berkeley. In that study, patients preferred the newer HD progressive lenses on every measure of satisfaction, including visual clarity, reading vision performance, computer vision performance and how easy the lenses were to get used to.
Next generation Bifocal Contact Lenses
The big advances in HD eyeglasses lenses have recently been matched by two next generation contact lenses that improve greatly upon older technology bifocal contact lenses. These lenses greatly reduce dependence on reading glasses when you wear contacts by providing crisp distance and intermediate vision. Reading vision is quite good too, but low power reading glasses are likely to be needed on occasion, especially if the lighting is poor or the print is very small.
If you are suffering from problems with the performance of your eyeglasses or contact lenses in the digital age, look for the advanced technology of new generation lenses to get you seeing all your devices more clearly with less eyestrain.
