Near Focus Spasm
Occasionally patients may experience accommodative spasm, an involuntary strain of the reading muscles in their eye. Near focus spasm can result in rapid eyeglass prescription change, headache, and blur; especially at night.
Near focus spasm often occurs slowly from over-use of the near focusing muscle of the eye, including excessive screen time or prolonged periods of reading. We often treat near focus spasm in our office with anti-fatigue contact lenses and eyeglasses.
Frequent breaks from near work is also recommended. Known as the 20-20 Rule, it is suggested to take a 20 second break after every 20 minutes of screen time.
