If my contact lens prescription is almost the same, would my glasses prescription have changed?

Published by admin under prescription contact lens

My glasses prescription last year was -4.25 and -4.00 with moderate astigmatism in both eyes.

And my contact lens prescription last year was -4.25 and -4.25

This year my contact lens prescription has not changed. Does that mean my glasses prescription has not changed either? Also this is the first time it hasn’t changed. Does this mean my vision is finally stabalising? I’m 24, had glasses since I was 6/7.

Since your contact lens prescription was -4.25 in both eyes then it is a certainty that your astigmatism correction must have been just around -1.00 diopter. The reason for that is that once your prescription hits the power of 4 either as a myope (near sighted) or a hypermetrope (far sighted) a small correction needs to be made to compensate for what is called the vertex distance or the distance between your cornea and the lens of the machine that the eye doctor uses to examine you. So normally your contact prescription should have been -4.00 & -3.75 once corrected for vertex. However in your case the eye doctor elected to compensate for your astigmatism using a sphere equivalent so that he/she can keep your costs down and use a regular spherical lens to provide you with an acceptable vision result. The classic method with the sphere equivalent calculation is that you take 50% of the astigmatism and add it to the overall contact lens power. And so you have the final prescription that you are wearing.

Is a contact lens prescription for only one brand?

Published by admin under prescription contact lens

I currently wear Acuvue Oasys for astigmatism and wanted to try colored contact lens. I saw that you can put in your prescription and order contacts online. Is the prescription on my box valid for all brands or just for Acuvue?

It will vary by your state, but usually a script is fitted for one type of lens. You can order them in any brand, but the company will usually check with your doctor to verify the prescription. Every type of lens sits differently on the eye. They come in various base curves and diameters. Its not a one size fits all thing. Some lenses might rotate more than others, and the doctor is the only one qualified to verify the fit.

And, honestly, if you wear Acuvue Oasys, you may find other brands a bit uncomfortable. (Not to mention colored toric lenses tend to be very expensive.)

Dark Brown Contact Lenses (Monthly Disposable: Prescription)

Published by admin under prescription contact lens

I have naturally BLUE eyes.

These contact lenses are:
IMAGES COLORS: DARK BROWN CONTACT LENSES
(MONTHLY DISPOSABLE: PRECRIPTION)

The lenses are OPAQUE (full block colour), so rather than enhance your natural eye colour, they dramatically change the eye colour.

Thanks for looking!

Buyer Beware: Optometrists Warn Consumers of Illegal Sales of Contact Lenses

With the arrival of the summer season, there is little doubt vendors will again be out in force, trying to take advantage of unsuspecting teens by selling them illegal colored contact lenses.

Illegal sales of cosmetic, colored lenses are problematic year-round, but particularly during the summer months, when boardwalk, street and flea market vendors, hair and tanning salons target young people. Of particular concern is that the lenses are sold illegally to teen-agers, who often receive little or no instruction on how to use them properly. As a result, young people develop dangerous eye infections, and in some cases, suffer irreversible damage to their eyesight.

Federal law forbids anyone other than an optometric physician or other licensed eye care professional from selling contact lenses without a patient prescription. Unfortunately, every year unwitting young consumers develop painful, debilitating eye conditions after wearing nonprescriptive cosmetic lenses.

NJSOP Warns Consumers: The Illegal Sale of Cosmetic Contact Lenses

Did you know that in the United States, you must have a prescription for any type of contact lenses, whether you need vision correction or not? If you answered no then you are not alone. In fact, the New Jersey Society of Optometric Physicians (NJSOP) has received many reports of patients (especially teenagers) who suffered from severe eye problems as a result of having purchased and used plano (non-prescriptive) cosmetic lenses from a non-physician. The worst part is that not only are these types of lenses being sold illegally to unsuspecting consumers, but they are also being sold without the proper instructions on how to use them.

This is a growing concern among the many members of the NJSOP, which is why we teamed up with Philadelphia news station, NBC-10. With our help, their investigative team went undercover to expose the vendors who sell lenses illegally. Please take a moment to watch this important story.

The NJSOP wants to warn consumers that this is truly a buyer beware issue. A contact lens that doesnt fit properly or isnt sterile, can lead to corneal ulcers, scratches, infections and other severe eye conditions. In addition, there is no way to guarantee the condition of these lenses if you do not buy them from a licensed eye care professional. The lenses could be expired, defective or even used. Remember that contact lenses are medical devices and whether you are wearing them for vision correctness or strictly for cosmetic purposes, they can greatly affect the health of your eyes. When properly prescribed, contact lenses can improve vision and quality of life. However, when dispensed inappropriately or without the supervision of a licensed eye care professional, these same lenses can lead to severe complications, including irreversible vision loss.

Other hazards associated with unauthorized contact lenses include bacterial infection of the eye, corneal ulcers, scarring and corneal thinning. Patients can reduce these risks by following the proper handling and cleaning procedures as directed by their optometric physician.

The NJSOP recommends to anyone interested in wearing contact lenses, whether for prescriptive and/or cosmetic reasons, to visit with an optometric physician or eye care professional to choose the right lens size, shape and material for their eyes.

Optometric physicians warn wearers not to share their colored contact lenses with friends. By doing so, harmful bacteria may be transmitted, which can lead to eye infections or other potentially dangerous eye conditions. These types of conditions serve as a strong reminder of the importance of obtaining a prescription from an optometric physician before purchasing any type of contact lenses.
