Does Reading Increase Eye Pressure?

In healthy young subjects, reading or writing on smartphone significantly increased IOP, and the changes of IOP were faster and greater under the low-light condition.

Can reading affect glaucoma?

Decreased reading ability at the early stages of glaucoma may be correlated with decreased contrast sensitivity due to the loss of retinal ganglion cells, which occurs earlier than any detectable loss of visual field, the authors noted.

What causes eye pressures to rise?

The cause of elevated eye pressure, known as ocular hypertension, is an imbalance in production and drainage of aqueous humor, the fluid inside your eye. Pressure builds as the eye creates new fluid and the channels which normally drain the aqueous humor become obstructed or damaged.
