Can I use my contact prescription for glasses?

Can I use my contact prescription for glasses?

The answer is no. While they both have the same objective — to correct what eye doctors call “refractive errors” that prevent you from seeing correctly — prescriptions for eyeglasses and contact lenses are distinctly different.

Should my glasses prescription be stronger than my contacts?

Contact lenses made to conform to a glasses prescription would be stronger than necessary, which could cause vision problems. Finally, your glasses are shaped to correct for astigmatism (irregular curve in the cornea or lens). However, contacts must be designed to fit the astigmatism, if there is one.

Is 4.25 A strong prescription?

If your number is between -0.25 and -2.00, you have mild nearsightedness. If your number is between -2.25 and -5.00, you have moderate nearsightedness. If your number is lower than -5.00, you have high nearsightedness.

What happens if you wear prescription glasses over contacts?

Yes. You can wear glasses and contact lenses at the same time.

Many people do this because it fixes multiple issues they might have with their vision. The glasses might help with reading while the contacts improve farsightedness.

What’s the difference between glasses prescription and contact prescription?

Are glasses prescriptions and contact lens prescriptions the same? A glasses prescription is not the same as a contact lens prescription. Glasses sit slightly away from your eyes and contact lenses sit directly over your eye, so two different tests and measurements are required.

Will my contact lens prescription be the same as my glasses?

What power should my contact lenses be?

The correct power should normally give you 20/20 vision. If your prescription shows a minus sign (-) this means that you are short-sighted and have myopia. If your prescription shows a plus sign (+) this means that you are long-sighted and have hyperopia.

How do I know if my contact prescription is too strong?

When your prescription is too high, you will notice that you begin to feel dizzy and nauseous within some time of wearing your prescription glasses or lenses. This is a sure indication of a wrong prescription.

Can you switch back and forth between contacts and glasses?

You can absolutely own both glasses and contacts, and switch between them as you see fit based on your work, comfort or lifestyle needs on a given day.

Why do I see better with glasses than contacts?

For starters, although they have the same strength and focusing power, contacts are much closer to the eye than glasses. This means they bend light in a way that more accurately meets your prescription, and so if you switch from glasses to contacts they can appear to slightly increase your visual acuity.

Why do I see better with contacts than glasses?

Another reason contacts can appear to provide better vision than glasses is the fact that glasses are exposed to the elements. The glass lenses are magnets for dirt and debris, are easily smeared by fingerprints, and love picking up little scratches and blemishes.

Is a contact lens prescription the same as for glasses?

In most cases a contact lens prescription is not the same as for glasses. The reason is the reduced distance (vertex distance) between the contacts and the eyes compared to glasses. When the contact lens prescription is lower than four diopters in lens power it is more likely to be the same.

How do I tell my eye doctor I want to wear contact lenses?

It’s important to tell your eye doctor you want to wear contact lenses so they can get all the right measurements. The office visit will start with the typical tests including identifying the clearest lens type for you, reading the eye chart, and having your vision measured using computerized machines.

What is the cylinder number on a contact lens prescription?

A contact lens prescription may also include an axis and cylinder if it is a toric lens for astigmatism, or an add if it is a multifocal lens, these are the only two measurements that can be found on both contact lenses and glasses prescriptions. You’ll find that the cylinder number on a contact lens prescription is always a minus number.

Do contact lenses make you less nearsighted?

Since eyeglasses are usually about 12 millimeters from the eye, the prescriptive power of a contact lens — which is positioned directly on the tear film of the eye — will be slightly less nearsighted. This becomes significantly different with prescriptions of 4D or greater.
