Welcome to Envision Optometry in Bellevue, Washington

We can help! There are various eyeglass lenses and lens coatings for people of all ages to relieve digital eye strain and ease fatigue after extended reading or computer use. Lens treatments, such as anti-reflective and blue light blocking coatings, protect your eyes and increase comfort. We also prescribe many different types of contact lenses to reduce reading discomfort and make it easier to switch focus from near to far.

Reading from a tablet or smart phone in the dark is okay for your eyes, as long as it's not for a long period of time. There is good lighting from these devices, with good contrast. There is, however, blue light emitted from these devices. Blue light is a short wavelength light, with high energy that may cause damage to the structures of the eye if exposed for a long period of time. As well, studies have shown this blue light can disrupt melatonin production which is required for a healthy sleep cycle. Optometrists recommend limiting screen use during the last hour before bedtime.

Usually we recommend that the height of the monitor should be level with the tip of your nose. The screen should be 26 - 30 inches away from your eyes. You can prevent glare from the screen and the harmful effects of blue light by wearing anti-glare lenses and blue light protection. In addition you should follow the 20-20-20 rule. For every 20 minutes of computer use, you should take a break for 20 seconds by looking at an object that is 20 feet away from you. If you feel that your eyes are suffering from computer use, please call to make an appointment so we can evaluate your condition.
