Varilux lenses are available in a variety of different materials that will reduce both thickness and weight. Smaller frames also reduce lens thickness and weight. We at American Vision Care will consider prescription, frame size, and your individual lifestyle as factors in helping you decide which lens material will be best for you.

Yes, you can get high index lenses to help with the weight and the thickness. There are many different levels of high index lenses to choose from. Also, careful frame selection can minimize the lenses thickness.

Since edge thickness is a function of lens power, centre thickness and curvature of the front and back curves (all inter-related) the edge thickness is influenced by the following features:

Most safety glass lenses are today made from Polycarbonate, and this is a very tough material. The impact resistance of a Polycarbonate lens is approximately ten times higher that of a safety glass lens made from hardened glass. Both these lens types (has the potential to) meet the requirements of the Eye and Face Protection Standard, ANSI Z87.

The drugs in topical pain relievers usually fall into the "caine" family. The percentage of the drug allowed by law (for non-prescription sale) is set relative to its effect. As an example, lidocaine, with moderate anesthetic properties is limited to 4 percent, but benzocaine, with very weak analgesic properties can contain up to a 20 percent concentration. Both will produce relatively the same effect.

Your eyeglass prescription contains information regarding the lens power required to correct your vision problems. It consists of spherical power, cylindrical power, cylinder axis, bifocal addition, and prism power. Your prescription will contain only those numbers that are pertinent for your vision correction, for example if you do not have astigmatism, you would not have a cylindrical power and axis information in your prescription. Most prescriptions do not contain prism power.

Once the 10+” of wool layers are stuffed into the cotton cover, the final thickness of the Cuddle Ewe Underquilt is approximately 3”. With use, the Cuddle Ewe Underquilt will compress to a thickness of about 1.5” to 2”. This is very normal and to be expected. Once the wool has compressed, there is nothing that can be done to re-fluff it, but it will still be comfortable. With proper care, you can maintain the Cuddle Ewe’s loftiness for a long time.

You must have a prescription for corrective lenses which is not more than 12 months old. You may have your eyes examined by any qualified eye specialist. Fermilab does not pay for eye exams.

With LASIK at Graystone Eye, we have the ability to correct a range of nearsightedness from approximately -1.00D to -12.00D or higher. Farsightedness is more limited. We typically are comfortable correcting up to +6.00 diopters. Sometimes, if the patient's prescription is higher, refractive lens replacement may be a better option for correcting the vision. Yes, we have the ability to correct astigmatism with the LASIK procedure. We can currently correct astigmatism up to 6 diopters.

Standard plastic CR-39 is covered in single vision and flat top bifocal lenses unless prior authorization is obtained from Avesis.

The thickness of the windows, without the additional glass layer that covers both sides of each window for protection, is between 8.5 cm and 13.5 cm, depending on its size. The bigger the window, the greater the pressure bearing on it and therefore the thicker it is. In addition, as mentioned, each window has a 6mm thick layer of special glass. The internal layer protects the acrylic panel from the visitors inside the Red Sea Star and the external layer protects the window from divers, fish etc.

Yes, there are two ways of writing a prescription for astigmatism. Some prescriptions are written in (-) cylinder and some are written in (+) cylinder. These prescriptions are equal even though they may not appear so.

No, you cannot use your eyeglass prescription to order your contact lenses. Contact lens prescription and eyeglass prescription are different. It should be noted that the power of a contact lens would not necessarily be the same as that of a spectacle prescription due to the optics of a lens being closer to the eye.

After the completion of a patient's comprehensive eye examination, and upon the patient's request, a copy of the patient's prescription for eyeglasses shall be given, free of charge, to the patient or to another optometrist, ophthalmologist, or ophthalmic dispenser acting on the patient's behalf.

Yes, if you got them from us, the containers have not been opened, and they have not expired. Bring them into the office rather than using the mails.

We would need to see you for the initial fit and follow-up visit. We recommend getting at least the initial lenses from us in case there is a problem. However, we can give you a prescription as long as we have seen you for a follow-up after the initial fitting while wearing the lenses. Most places will only honor a contact lens prescription for a year, so you would need to be seen every year by the doctor to update your prescription, if you fill it elsewhere.

Miracle Lens™ and Miracle Lens Plus™ lenses would work perfectly. Both are state of the art, remarkably thin lenses that provide not only a tremendous amount of comfort, but scratch and impact resistance as well.
