Question 1

what is the highest and the lowest diopter on a corrective lens?

Accepted Answer

+6 to -20: There theoretically is no limit but practical limits are about +6 to -20.  Beyond these ranges, contact lenses, implantable lenses or elective cataract extractions are realistic alternatives (refractive lens exchange).

Question 2

what is diopter in prescription lens?

Accepted Answer

Power designation: This is a term from optics indicating the light bending ability of the lens in question.  The number is generated in the process of refraction in the ophthalmologists office, and then written on the prescription so the optical shop can make the lenses of the proper power.

Question 3

how do i improve my eyesight without using corrective lenses?

Accepted Answer

See explanation.: That is why they are called corrective lenses.  The only other alternative is refractive surgery or contact lenses.

Question 4

are glasses and corrective lenses the same thing?

Accepted Answer

Generally: Corrective lenses adjust the focus - they can be glasses or contact lenses.

Question 5

can you wear corrective lenses that improve sight even if you have 20/20 vision?

Accepted Answer

I do not: Think such lenses are necessary.

Question 6

can corrective lens make your vision worse?

Accepted Answer

No: Glasses are designed to improve the focus of the eye and improve clarity. Sometimes patients who start wearing readers feel that their near focus becomes more difficult and to a certain extent this is true. But eventually, readers become essential whether glasses are used initially or not.

Question 7

how can you improve your vision without utilizing corrective lenses?

Accepted Answer

Yes: It depends on the reason for the decreased vision. Vision can be decreased because the light coming into the eye is not getting focused perfectly on the retina (the layer of film in the back of the eye that captures the light). This is called refractive error. In addition to glasses and contacts, there are surgeries available (like lasik and prk) that can correct refractive error.

Question 8

can i determine my vision from my corrective lens prescription?

Accepted Answer

Not really: The numbers in a prescription only define far or nearsightedness and astigmatism.  Rough estimates can be extrapolated from the prescription but can be affected by retinal, corneal or lens disease.  The best way to see what the "best corrected" vision with glasses is to use an eye chart.

Question 9

how are people with glasses (corrective lenses) able to watch 3d movies?

Accepted Answer

Wearing 3D glasses: The 3d glasses can be slipped over the prescription glasses generally without difficulty. Some are very cheaply made from cardboard with thin plastic lenses, but flexible enough to be worn over glasses.

Question 10

how can one gain back his normal eyesight without using corrective spectacles / lenses?

Accepted Answer

Laser or IOL: Laser vision correction (lasik or prk) or refractive lens surgery with placement of an intraocular lens (iol) are other ways to correct your vision. Discuss the various options with your ophthalmologist (eye md) to see what's best for your particular situation.
