How Lighting Affects Your Vision

Everyone’s eyes, even those with perfect vision, are affected by lighting. Just consider how difficult it can be to read in dim lighting, or how much further you can see during the day, as compared to dusk, dawn, or even night. It is obvious we need light to see, but just how much light is the perfect amount?

Even a small change in the amount of light available in a room can have a noticeable impact on vision. Keeping this in mind may help make things clear for your next eye exam. A study published in the online journal JAMA Ophthalmology, compared the results of eye exams conducted at locations with different lighting conditions.

The researchers noted that patients sometimes complain of vision problems, but perform perfectly on vision tests given at the eye doctor’s office. They speculated that the discrepancy may be due to a difference in lighting conditions between the eye center and the patient’s home. They then conducted the same eye exams in both a clinical setting and in the home.

The results showed that patients did perform better on eye exams given in an office setting. They measured the light at both locations and found that the lighting in home was “4.3 times and 2.8 times lower than clinic lighting.” The study  also showed that this effect was even greater in patients with glaucoma.

For those who have 20/20 vision, but still seem to experience vision problems in the home, this is good news. You may not have anything wrong with your eyes. The problem could be with your home lighting. Try increasing the amount of light in your home by adding lamps, new fixtures, or letting in more natural light through windows. It is still a good idea to check with your eye doctor to rule out the possibility of eye conditions. Schedule an appointment with one of our eye doctors today.
