“Continuous focusing and refocusing and exposure to LEDs and blue light when using computers and mobile devices can lead to eyestrain and eye fatigue. Strained and dry eyes, blurred vision, tiredness, headaches and neck and back pain are symptoms of spending too much time in front of a computer. Digital lenses help to provide clear, relaxed vision throughout the day and less eye fatigue at night. These are recommended for anyone who is suffering symptoms such as digital eye fatigue.”
According to Naude, indoor computer lenses have evolved considerably over the years and lens options are available to cater to different focal distances.
“Instead of wearing progressive lenses, which has three focal distances, namely near, intermediate and far, you can now keep a dedicated pair of indoor lenses on your desk. Indoor lenses have a clear reading area and a wide field of view in the intermediate area. You can discuss your working distance with your optometrist and they can prescribe a lens specifically for your needs. For example, if you spend most of your working day on your computer, your intermediate working area will be approximately 50cm to 1m away, so this area of the lens will be optimised accordingly.”
He concludes saying that “lifestyle” should always be considered in the assessment and purchase of prescription lenses to optimize vision and the overall experience of the wearer.
“If your prescription lenses don’t fit your lifestyle, you will not enjoy wearing them, they will not do the job that they are meant to do and you might stop bothering with them altogether.”
