How is the refraction test used to diagnose presbyopia?
1 doctor answer • 5 doctors weighed in
Dr. Richard Bensingeranswered
Ophthalmology 52 years experience
Age related: Presbyopia is tested for after age 40 or so. It is due to the inevitable hardening of the lens which becomes visually evident between ages 40-55 when the lens no longer is flexible. It is tested in that age group by near vision apparatus in your ophthalmologists' office however there are formulas which can be used which are reliable for power and commonly applied without testing after refraction.

What causes errors of refractions?
1 doctor answer • 1 doctor weighed in
Dr. Tim Conradanswered
Ophthalmology 34 years experience
Imperfect eyes: An error in refraction is imbalance between the amount of light-bending (refraction) an eye needs and what it has. A perfectly refracted eye bends the light the exact amount to focus on the retina. Most eyes are not perfect and need to lessen (in nearsightedness) or increase (in farsightedness) the amount of bending. This is done with glasses, contacts or surgery.
