Research published in JAMA Ophthalmology highlights the issue of differing results from corrective eyeware between the optician's office and home for senior citizens.
Patients that were able to see clearly while at their optician’s were not able to see as well once they had returned home. The cause of this chance in vision is poor lighting.
The study focused on 175 eye patients between the ages of 55 and 90, most of whom had been previously diagnosed with glaucoma. Each participant was given a comprehensive eye exam, both at their eye care practitioner’s office, as well as at home. Each test was within one month of the other, and both took place during daylight hours.
The home tests included extra tasks that measured their performance at tasks that require near-vision, like paying bills and reading. Digital light monitors were used to measure light levels, both at home, and in the clinic.
Across the board, test results were significantly better in the more brightly lit optician’s testing room, even for the few patients who did not have glaucoma.
Greater improvements in vision were recorded in patients with more severe glaucoma. The results show that improved lighting helped with eyesight in both near, and distance vision.
For senior citizens struggling with poor eyesight, it is strongly recommended to upgrade to brighter light bulbs at home, in addition to any corrective eye are prescribed by your doctor.
