- Presbyopia
Presbyopia is physiological insufficiency of accommodation associated with the aging of the eye that results in progressively worsening ability to focus clearly on close objects. Symptoms include difficulty reading small print, having to hold reading material farther away, headaches, and eyestrain. Different people will have different degrees of problems. Other types of refractive errors may exist at the same time as presbyopia.Presbyopia is a normal part of the aging process. It occurs due to age related changes in lens (decreased elasticity and increased hardness) and ciliary muscle power of the eye, causing the eye to focus light behind rather than on the retina when looking at close objects. It is a type of refractive error along with nearsightedness, farsightedness, and astigmatism. Diagnosis is by an eye examination.Presbyopia can be corrected using glasses, contact lenses, multifocal intraocular lenses, or LASIK (presbyLASIK) surgery. Most common treatment is glass correction using appropriate convex lens. Glasses used to correct presbyopia may be simple reading glasses, bifocals, trifocals, or progressive lens.People over 40 are at risk for developing presbyopia and all people become affected to some degree. Around 25% of people (1.8 billion globally) are currently affected.
