Frequently asked Patient Questions to our Eye Doctor in Mansfield, DeSoto and Fort Worth:
Q: I work all day on my computer. How can I reduce the strain to my eyes?
A: 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.
Q: Why do my eyes tear up when I am reading or spending time in front of a computer?
A: This may be due to a decreased rate of blinking as you concentrate on reading or working on the computer. When you blink less, less tears are pumped out of the tear drainage system, leading to a welling of the tears. Also, if you have an unstable tear film in conjunction with a decreased rate of blinking, this could lead to reflex tearing. Patients who experience this often have evaporative dry eye, which could be diagnosed with some additional testing.
Q: Does reading my smart phone or tablet in the dark damage my eyes?
A: Reading from a tablet or smart phone in the dark is okay for your eyes, as long as this is 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. Doctors of Optometry recommend limiting screen use during the last hour before bedtime.
