What can you use to clean a Prescription glasses?

I use glass cleaner and paper towels.

Mine came with a 3 ounce bottle of solution and wipes. After a year, I still have plenty. Guess your’s didn’t? Don’t use windex unless your lenses are definitely glass as windex will dull plastics. MG chemicals makes a nice aerosol spray cleaner designed for plastic and glass. (you didn’t mention which your’s are) Check it out here: http://www.mgchemicals.com/products/825.html

We sell it where I work for about $5.00 US. It’s very useful for all kinds of cleaning.

Hey vamsi: You used an atomic bomb where a little firecracker would have sufficed. Nobody’s going to read all that.

’nuff said?

I bought a glasses cleaning clothe from CVS. You never have to wet it or anything.

But sometimes a little puff of breathe and a paper towel will do the trick.

You can use plain dish soap and water and a soft cloth to dry with. Paper towels are a bad idea as they have fibers that will scratch the lenses.

If they are plastic, do not use paper. The paper fibers scratch.

Lens cleaner is great, if you have it. I just use mild soap, and water, and a soft cloth on my plastic glasses.

Dish soap.

Wash your fingertips clean of oil with it and rinse your fingertips.

Place a drop or two of dish soap on the lens and rub around with clean fingertips.

Rinse the soap off in the hottest running water you can, then blot dry. You will be amazed at how clean, streak and oil free they will be.

Lens cleaner and a soft cloth.

i use windex if i dont have eye glass cleaner, i also use a tea towel that is polyester/cotton, the ones that dont get little balls of fuzz on them. this works great for me

LITTLE PACKETS OF DISPOSABLE NO SCRATCH CLEANERS ARE SOLD AT EVERY BIG DRUG STORE ….ALSO AT THE OPTO OFFICES AND LENS CRAFTERS ETC…….

Prescription reading glasses

If you need vision correction only for reading and you do not have astigmatism, then you can buy non-prescription reading glasses. If you do have astigmatism, you need prescription reading glasses. In either case, these are still considered single vision lenses.

Non-prescription reading glasses simply magnify objects that are close to us, like the letters in a book. Your eye doctor can determine the magnification “power” that is best for you, or you can figure it out by yourself through trial and error. A doctor’s prescription is not required in order to select a reading lens. Drugstore “reading glasses” are simply eyeglasses frames with magnifying lenses “pre-loaded” in a range of powers with stock lens powers. It is usually less expensive to purchase reading eyeglasses this way, but stock lens powers rarely provide a optimal vision correction. For best results, reading lenses with magnification customized to your needs can be installed in any pair of eyeglasses frames.

PRESCRIPTION EYEWEAR LENS TYPES

Once you have determined the best lens type for your lifestyle, preferences, and budget, you can then choose the lens material. There are three basic types of lens material for prescription eye glasses–hard resin plastic, polycarbonate plastic, and high index plastic.

The rule of thumb

If your prescription is lower than +/-4.00, then hard resin is the best choice for you. If it is above +/-4.00, then high index plastic is best for you. If you are a child or an active adult and need some eye protection, then polycarbonate is best for you.

Hard resin lenses are good for most people. Polycarbonate lenses are virtually shatterproof, and are highly recommended for children and active adults. By “active” we refer to any activity that includes a possibility of receiving a blow to the face. For example, policmen, firemen, tennis and ball players, aggressive sporting activities—just to name a few. Wearing polycarbonate lenses may not save your eye, but they will certainly help, and a little added protection can’t hurt!

In general, if the sphere on your prescription is at +/-2.00 or lower, you will not benefit from the more expensive “thin” high index lens types. Hard resin or polycarbonate lenses will be just fine for you. If the sphere on your prescription is higher than +/-2.00, you will benefit from the selection of a “thin” lens type. Thinner lenses have three advantages: they do not look “thick”, they do not magnify or minify your eyes when seen by others, and they are lighter.

In general, the thinner and lighter the lens, the more expensive it will be. “High index” is the most common “thin” lens material, and “aspheric” is the most common “thin” lens design. Polycarbonate lenses can be purchased as “aspheric”, giving you the advantage of polycarbonate’s strength together with aspheric’s thinness. The thinness of high index lenses is characterized by the “index of refraction” (IR). Mid-high index lenses are commonly around a 1.56, high index lenses are around 1.60, and ultra-high index lenses are 1.66 and above. All rimless eyeglasses must use polycarbonate, Trivex, or high index lenses to avoid cracking.

After you have selected the best prescription glasses lens material for your personal situation, you can choose among other lens features and options, like sun-sensitive, scratch coating, anti-reflective coating, and UV protection (UV protection is always inherent in high index and polycarbonate lenses). If you want sunglasses, additional options could include tint, polarization, and mirror coatings. Additional lens services would include a mounting fee (applies only for rimless frames), and rolling and polishing (applies only to higher power lenses being mounted in certain frame types). For more information on the various lens options, follow this link to eye glasses lenses.

How thin are the thin lenses? How thick are the thick ones?

The plastic used for lenses in prescription eyewear must have at least a 2.0 mm center thickness according to US law. The thickness at the lens edge depends on the strength of your prescription, your pupillary distance, the eye size of the frame, and the lens material. Because of all of these factors, it is nearly impossible to select a lens by its “thinness”. In general, the thinner and lighter the lens, the more expensive it will be. To make the optimal thickness/price choice for your personal situation, use the chart above as a guideline. You can choose to spend less money and have a thicker lens, or more money to have a thinner lens. Also, within the mid-high index, high index, and ultra-high index categories you can also choose an aspheric design for additional thinness.

NEW LENSES

Adjusting to lenses

You will need to learn how to adjust yourself to your new glasses, whether you get your new glasses from eyeglasses.com or any other optical store. The adjustment period could be very quick, or it could take a month, depending on you, your glasses, and your prescription. There are some ways to make the process easier, and to solve problems more quickly.

If your prescription is lower than +/-4.00, then hard resin is the best choice for you. If it is above +/-4.00, then high index plastic is best for you. If you are a child or an active adult and need some eye protection, then polycarbonate is best for you.

Common adjustment problems and solutions

It is very common to experience a feeling of disorientation while you adjust to your new glasses. If you are having trouble adjusting to your new glasses, work through this list in order:

1.

If your prescription has changed recently, your eyes need extra time to adjust to the new lens.

2.

If you are wearing multifocal lenses (progressive, bifocal, and trifocal lenses), you must learn to move your head, not your eyes.

3.

The center of the lenses must be positioned directly in front of your eyes. Make an adjustment to the positioning of the glasses on your face, and be sure the glasses stay in that correct spot.

4.

) If you tried #1 through #3 and you still cannot adjust to your new glasses, it is possible that the pupillary distance measurement was taken incorrectly. It is also possible that your eye doctor gave you the wrong prescription (sometimes they do make mistakes!)

5.

If you tried #1 through #4 and still are not satisfied with your lenses, send the glasses back to us (if you bought them from us). We will double check to be sure that we made the lenses exactly to your specifications. We will then give you a full refund.

READ YOUR PRESCRIPTION

We strongly recommend that you fax your prescription to us. We can read your prescription and then help find the best prescription eye glasses lens for you. For multifocal orders, we require that you fax your prescription to us.

Your prescription

Prescriptions have a certain format that is typically followed. The first line of your prescription is always for the right eye, sometimes designated the “OD”. The second line is for the left eye, sometimes designated “OS”. The prescription for each eye is divided into Sphere, Cylinder, and Axis values. It is common to have no values for any one of these, in which case you might see the letters “PL” or “plano”, or to have values for all of these. Sometimes the prescription may say “OU” which means “both eyes”.

Multifocal prescription

If your prescription is for bifocals or trifocals of progressive lenses, there may be additional information on the prescription that says for example “Add +2.50”. This is important information if you are ordering reading or multifocal lenses. The numbers are expressed in diopters (a universal value system) that tells the power of the lens.

On a prescription for multifocal glasses lenses, you will see information designated as “add power”. Your “add power” is simply the magnification that is added to your sphere value for distance vision, in order to create a field of view for reading. For example, if your sphere value for distance viewing is –3.00, and your add power is +2.00, then your near vision correction is –1.00. Or, if your sphere value for distance viewing is +1.00 and your add power is +2.00, then your near vision correction is +3.00.

Pupillary distance PD

An accurate PD is a required measurement in order to make prescription glasses, and you cannot purchase from eyeglasses.com without one.

Your PD is the distance in millimeters between your pupils (the centers of your eyes). Your adult PD never changes, and it averages 60 millimeters (mm) for women, and 64 mm for men. Sometimes your eye doctor will write your PD for each eye (for example “33/34”, called a monocular pd). Or, the eye doctor may write the PD as “67/64”. This means that your PD for distance vision (or DPD) is 67, and for near vision (or NPD, for reading eyeglasses or multifocal lenses) it is 64. Your near vision PD is almost always 3mm less than your distance vision PD.

CLEANING

Cleaning prescription lenses

The best cleaning method for eyeglass lenses and sunglasses, including lenses with anti-reflective coating always begins by moistening the lens. Lenses should never be cleaned dry, never with a piece of clothing or a paper towel or toilet paper or Kleenex containing moisturizer. To clean your lenses, start by putting your glasses under lukewarm running water. Get your finger tips soapy, and gently rub the lens. Rinse soap off the lenses, and then pat dry with a microfiber lens cleaning cloth. Never rub the lenses with any cloth, just dab them until the water droplets are gone.

Cleaning prescription glasses frames

Cleaning your glasses is also best done with soapy warm water. You can also take your prescription glasses to a local optical stores, which has a machine for cleaning eyeglass frames. However, if your frame has any inlaid gems, you should not have them cleaned by machine, only by hand.

COMMON QUESTIONS

Can I hurt my eyes with the wrong lenses?

There is no clinical evidence to suggest that looking through lenses with the wrong prescription or pupillary distance configuration can cause damage to your eyes. However, there could be other undesirable consequences (especially for people with stronger corrections), such as headache, dizziness, and vertigo. Some of these effects could cause a dangerous situation if you are driving, handling machinery, or otherwise reliant on your eyeglasses for your safety or the safety of others.

You may experience some of these effects with a new pair of prescription eyeglasses, or a new prescription. The effects could fade over time, but we strongly suggest that you visit your local optical professional in order to determine the best course of action.

Can my new prescription eye glasses make me dizzy or give me headaches?

No. Prescription eyewear lenses cannot be separated from lens installation. Lenses must be purchased and installed by the same company. However, it is possible to buy prescription frames from one store and have the prescription glasses lenses installed at a different store.

Can I buy prescription lenses from one store, and have them installed elsewhere?

No. Prescription eyewear lenses cannot be separated from lens installation. Lenses must be purchased and installed by the same company. However, it is possible to buy prescription frames from one store and have the prescription glasses lenses installed at a different store.

My frames are broken, but my lenses are still good? Can I reuse them?

Prescription glasses lenses can often be re-cut to fit new prescription frames, but there are some restrictions. The new prescription frame must either be the exact same frame model and size as the broken frame, or it must be smaller in every dimension (height and width). Your local optical retailer should be able to examine your prescription lenses and help you select a new prescription frame for them.

Does it matter which lens brand I choose?

Your choice of prescription lens brand is a personal decision, which is generally a tradeoff between price and quality. In general, better quality brand merchandise is more expensive. In prescription lenses, a more expensive lens usually means a better quality lens, or a lens with a wider viewing area (in the case of progressive lenses). In some cases however, it may be difficult or impossible for a consumer to notice the difference between a high quality prescription lens and a low quality lens. Anti-reflective and scratch-resistance coatings typically adhere better to the lens if they are applied by the lens manufacturer than if it is applied by a lens laboratory.

Prescription Safety Glasses

We do not sell safety glasses at eyeglasses.com. There are many different types of safety lenses and eyeglass frames depending on your job or your activity. Safety glasses should only be dispensed in consultation with your eye doctor and local optical professionals.

Children’s Glasses

We offer a selection of prescription glasses for children. The best way to begin fitting your child for prescription glasses is to get the child’s PD measurement. When you have that, you should call our customer service department and discuss the needs of your child, and we can either find the perfect prescription glasses for your child or refer you elsewhere.

Prescription sunglasses

You can build prescription sunglasses the same way as prescription glasses. Begin by selecting a pair of eyeglass frames or sunglass frames that can hold a prescription. Lower quality sunglass frames are not designed to hold a prescription lens, and are called “non-RXable”. RXable sunglasses are sunglass frames that can accept a prescription lens.
