How Do I Read My Glasses Prescription?

Ever wondered what all the letters and numbers in your glasses prescription mean? Wish you could understand and read your prescription?

Here’s a quick guide from our Midtown eye care team to help you become an expert at reading your prescription!

Your Glasses Prescription

If you take a look at your prescription, you’ll notice a few numbers listed under different labels: OS and OD, or OU.

What do these labels mean?

– OS: oculus sinister, referring to the left eye

– OD: oculus dextrus, for the right eye

– OU: oculus uterque, both eyes.

Although these Latin terms are still widely in use, some eye care offices are beginning to move toward using English-based abbreviations: RE, for the right eye and LE for the left one.

How to Read Nearsighted and Farsighted Prescriptions

When reading prescriptions that correct for nearsightedness or farsightedness:

  • The further from “0” the number is, the stronger the prescription
  • + refers to a farsighted prescription
  • – refers to a nearsighted prescription

As examples:

  • -1.00 would represent very slight nearsightedness, whereas -6.00 or more would represent more severe nearsightedness.

The same applies to farsightedness

  • +1.00 would be slight farsightednees, and +6.00 or more would be more severe farsightedness.

What About My Astigmatism Prescription?

Because astigmatism creates a more football shaped cornea, rather than a round one, there are extra items to consider. Your prescription will therefore lookquite different.

Here are the elements of an astigmatism prescription:

  • SPH: measures how nearsighted or farsighted you are.
  • C or CYL: shows how astigmatic your eyes are. The number can be negative or positive, and the bigger it is, the stronger your astigmatism.
  • Axis: This number will be between 0 and 180 degrees, and tells your optician where exactly the curvature in your cornea is, and how it’s positioned.

What Other Measurements Might Be In My Lens Prescription?

ADD: This represents the additional correction needed for presbyopia. It measures your need for bifocal or progressive lenses, and is a way of adding two different prescriptions together, to address the issues causes by presbyopia at all visual distances.

PD (Pupillary distance): Refers to the distance, in millimeters, between both pupils in the eyes. This helps our Midtown optical team figure out exactly where you’ll be looking through your lenses for different visual tasks, and helps determine frames that are right for you, as well as the best way to construct your lenses to ensure the clearest most comfortable vision.

Q&A

Are contact lens prescriptions the same as glasses prescriptions?

No. Glasses and contact lens prescriptions are completely different. This is because glasses are placed slightly in front of the eye, while contacts rest on the eye itself. This creates a difference in how they reflect light into the eye and how they need to be constructed to properly correct your vision.

What glasses prescription represents legal blindness?

Legal blindness is defined by a person either having less than 20 degrees of vision as determined in a visual field test, or visual acuity of 20/200. This means that this person can only see clearly from 20 feet what a person with 20/20 vision could see clearly from 200 feet. This is the same as a prescription of -2.5.

The Advantages of Having Different Types of Glasses

Having just one pair of eyeglasses may seem economical, but it can leave your eyes vulnerable to the sun’s harmful UV rays, digital eye strain and sports injuries, and the possibility that you’ll be left without a spare pair if your glasses are damaged or misplaced.

Here are some reasons to have an assortment of glasses:

Relieve Digital Eye Strain

Many of us are spending more time online than at any time in the past. But our high-tech reality has a drawback: more time in front of the screen can lead to digital eye strain. Invest in a pair of computer glasses that have an anti-reflective coating and filter out blue light.

Protect Your Eyes from UV Rays

Numerous studies have shown that exposure to the sun’s UV rays increases the risk of developing eye conditions like cataracts and macular degeneration. Choose sunglasses that block 100% of UV rays.

Prevent Injuries with Sports Glasses

Having a dedicated pair of glasses for sports activities can protect your eyes from injury. Specially designed impact-resistant polycarbonate lenses are durable and comfortable.

Accidents Happen

All it takes to render a pair of glasses useless is to step or sit on them, or for a curious child to play with them. And that doesn’t include the times glasses get lost, or are left behind at school or the workplace. Having a spare provides peace of mind.

Broaden Your Selection

You may want to have a selection of glasses to go with certain outfits, to suit your mood or if you simply want a change. Having more than one pair of glasses with the same prescription is stylish and fun.

No Need to Wait

Prescription eyeglasses can take up to a week to replace. During that time, you may have difficulty seeing and engaging in everyday activities like reading and driving.

When reading glasses need replacing, there is a temptation to buy a cheap pair at the drugstore.

However, unlike prescription lenses, generic lenses aren’t customized for your vision. Having a spare pair of prescription glasses eliminates the anxiety associated with waiting for a new pair.

If you want to purchase an additional pair of glasses, contact our eye care professionals at James Tracey Eye Care for a consultation today.

Q&A

What are the advantages of prescription sunglasses?

Prescription sunglasses simultaneously allow vision correction and shield the eyes from glare and the sun’s UV rays. There is no need to adjust clip-on shades over your glasses or to wear contacts under non-prescription sunglasses.

Some prescription eyeglasses have polarized lenses with a filter that blocks bright reflections that can strain the eyes. Additionally, prescription photochromic lenses get darker as light becomes brighter so you can use the same glasses indoors and outdoors.

How do computer glasses relieve eye strain?

People who work at a computer for extended periods may develop computer vision syndrome, also called digital eye strain. This happens because the visual demands of computers and digital screens are different from those associated with reading, driving or simply looking at objects.

Using a computer requires frequent changes of focus from the screen to the keyboard and back. Computer glasses are designed to correct vision for seeing intermediately distanced objects, like computer screens. Also, special lenses can screen out blue light, which can contribute to digital eye strain.

3 Reasons to Wear Sunglasses All Year Round

Most people know the importance of wearing sunglasses during the summer, but many pack them away when autumn comes. That’s a mistake, because sunglasses can protect our eyes from harmful UV rays as well as glare and environmental irritants all year long.

Here are 3 reasons to wear sunglasses all year round.

  1. Summer may be ending, but UV radiation is not

The sun provides an endless supply of ultraviolet (UV) rays, which are hazardous to our health. These rays create a slew of issues in our skin and eyes, including wrinkles, sunburn, and skin cancer, and raise the risk of developing cataracts and age-related macular degeneration.

While it’s true that UV radiation levels are highest during the summer, it’s important to remember that the sun shines all year long.

  1. Sunglasses protect against the elements

Did you know that the sun isn’t the only potential source of eye damage? Sunglasses, especially ones that wrap around your face, can also protect your eyes from:

  1. Dust and Wind – Spending time in dusty, windy conditions can leave your eyes dry and irritated. Dust can even scratch your cornea.
  2. Sand – Getting sand in your eyes is not only irritating, but it can also be harmful. Small sand grains can scratch the surface of the eyes, causing irreversible damage. Sunglasses that completely protect your eyes are ideal for keeping sand out.
  3. Snow and water – Snow can reflect as much as 80% of the sun’s UV rays and bodies of water reflect 25% of the sun’s UV rays, and the glare can burn your eyes if you don’t wear sunglasses or UV protected goggles.

3. Fewer Migraines and Headaches

Wearing sunglasses can help minimize the severity and frequency of painful migraines and headaches brought on by intense sunlight. When you’re out in the sun, wearing sunglasses can minimize fatigue and eyestrain, making your eyes feel more comfortable.

Wearing sunglasses on a regular basis has several eye health benefits. Visit James Tracey Eye Care in Midtown; we can assist you in selecting the best sunglasses to safeguard your eyes.

Q&A

How do I know which sunglasses absorb UV rays?

When purchasing sunglasses look for a label that says 100% protection against both UVA and UVB or 100% protection against UV 400.

Is there a difference between regular sunglasses versus polarized sunglasses?

You’ll notice and appreciate the difference once you put on a pair of polarized sunglasses that also offer UV protection – not all polarized lenses do. The change in color and clarity is incredible. An ordinary pair of sunglasses is better than nothing when it comes to protecting your eyes from the sun (combined with wearing a hat), but polarized sunglasses that offer UV protection are unrivaled. Be sure to request that your polarized sunglasses also protect against UV rays.

7 Reasons To Wear Sunglasses

Designer Sunglasses & Optical Frames at James Tracey Eye Care

Sunglasses Not Only Protect Your Eyes, But They Look Great and Can Accommodate Every Style and Budget

How times have changed. This year, Summer is looking very different than it did a year ago. Yet despite COVID-19, it’s important to spend time outdoors, whether in your garden or on daily walks.

Although sunglasses are ubiquitous symbols of style, they also serve an important function in protecting your eye health.

7 Reasons To Sport A Great Pair Of Sunglasses

    • Sunglasses Provide UV Protection

When most people think about sun-related damage, they think about their skin. But the sun’s ultraviolet rays also pose a threat to a person’s eyes. Protect your eyes by wearing a pair of sunglasses that block 100% of both UVB and UVA radiation.

  • They Help Prevent Cataracts and Macular Degeneration

Both cataracts and macular degeneration are the leading causes of visual impairment and blindness worldwide. You’re at a higher risk of developing these conditions if you expose your eyes to excessive amounts of UV radiation. The risk can be minimized by wearing glasses that protect against this radiation.

  • Cataracts cloud the lenses of the eyes, causing blurred vision. Years of exposure to UV rays cause the protein in the lens of the eye to clump and thicken, preventing light from passing through it. ..
  • Macular degeneration refers to central vision loss due to a damaged retina. UV light can be harmful to the eyes, specifically the retina, and exposure to UV rays is a risk factor for the onset of age-related macular degeneration later in life.
  • Sunglasses Can Help Prevent Certain Cancers

Ultraviolet exposure has been associated with certain eye cancers and several types of skin cancer found on the eyelids. You can reduce your risk significantly by wearing a pair of sunglasses that offer 100% UV protection. Keep in mind that when choosing shades, it doesn’t matter how dark they are or the color of the lenses. The most important thing is that they block 99% to 100% of UVA and UVB rays.

  • Sunglasses Keep You Looking Younger

Though a stylish pair of shades makes anyone feel youthful on the inside, it can also make you actually look younger on the outside. By protecting the delicate skin around your eyes, sunglasses slow down the development of wrinkles and crow’s feet. This leads to a more youthful appearance over the years.

  • They Protect Highly Sensitive Eyes

If you have light-colored eyes, take medication that causes photosensitivity (light sensitivity), or have a medical condition that causes you to be more sensitive to light (such as dry eye, corneal abrasion, scleritis, or conjunctivitis) you’ll need to protect your eyes with UV-blocking sunglasses. Note that large sunglasses block more UV rays than smaller ones.

  • Shades Protect Eyes Recovering From a Medical Procedure

Eye surgeries such as LASIK or cataract surgery are common nowadays. You must continue to wear sunglasses following a procedure to prevent complications.

  • Sunglasses Enable You to See and Enjoy More

Aside from protecting your eye health, wearing sunglasses helps you see better in bright light. They reduce glare and improve the contrast of what you see, allowing you to better enjoy the sunny outdoors or drive more safely.

Frequently Asked Questions

Q: How do I know which Sunwear lenses absorb UV rays the most?

  • A: Generally, most Sunwear lenses will absorb UV lenses to some degree. Lenses that are marked CR-39R plastic, absorb about 88 percent of UV light. If sunglasses contain polycarbonate lenses, UV absorption will be 100 percent.

Q: Is there a difference between a cheap pair of regular sunglasses versus designer sunglasses?

  • A: I believe once you put on a pair of polarized sunglasses you will understand and appreciate the difference. the clarity and the color difference are amazing. It is also one of the best ways to protect your eyes from the sun’s harmful ultraviolet rays. A “regular” pair of sunglasses is better than nothing ( along with wearing a hat) in protecting your eyes from the sun, but there is no comparison to polarized sunglasses

Moreover, at James Tracey Eye Care, we offer a range of styles to choose from, whether you’re on a tight budget or want to splurge on high-end designer shades.

Why Are Blue Eyes More Sensitive To Light?

Did you know that blue eyes don’t contain any blue pigment? They appear blue due to how the light reacts with the structures of the iris.

In fact, the top layer of a blue iris doesn’t contain any pigment at all. This lack of pigment is the reason that blue-eyed people may be more sensitive to bright light and have a greater need to wear sunglasses than their brown-eyed counterparts.

Why Do Your Eyes Need Sun Protection?

Eyes of all colors need shielding from the sun’s harmful ultraviolet (UV) rays. Exposure to UV light can contribute to the formation of short-term and long-term eye conditions such as corneal sunburn and macular degeneration.

That’s why it’s so important to choose high-quality sunwear with 100% UV blocking lenses, and to throw on a sun hat for an added layer of protection.

UV protection is important for individuals of all ages—especially children—who are more susceptible than adults to the sun’s harmful rays, and tend to spend more time outdoors. It is estimated that up to 80% of a person’s lifetime exposure to UV rays happens before the age of 18.

Why are Blue Eyes More Sensitive to Light?

Lighter colored eyes like blue, hazel and green have less of a pigment called ‘melanin’ than brown eyes do.

Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.

If you have blue eyes, you may have experienced this first-hand. Bright light may be uncomfortable or you may want to reach for your shades as soon as you leave the house on a sunny day.

That’s why optometrists urge blue-eyed patients to be particularly vigilant about UV protection, so as to mitigate their chances of developing eye disease and other complications.

How We Can Help

Whether you have blue eyes or not, sunglasses are an important part of keeping your eyes healthy for a lifetime.

At James Tracey Eye Care, we’ll be happy to advise on the perfect high-quality and protective pair of sunglasses to suit your needs and personal style.

Frequently Asked Questions with James Sinoway O.D.

Q 1: Should I wear sunglasses even when it’s not sunny outside?

  • A: Yes! You should wear your sunglasses whenever outdoors during the day, even on an overcast, winter day. UV light can pass through clouds and reflect off surfaces like car windows and pavement.

Q 2: What type of sunglasses are the most suitable for blue eyes?

  • A: The most protective sunglasses are wraparound sunglasses that protect the eyes from every angle. You can also opt for photochromic lenses, which offer total UV protection but only become tinted when exposed to outdoor sunlight, and turn clear when you come indoors again. Your optometrist can help you choose the best lens and frame options for your needs and lifestyle.

How To Prevent Your Lenses From Scratching

If you wear glasses, then you know what a nuisance a scratched lens can be. Scratched or chipped lenses can interfere with your vision, making glasses uncomfortable to wear. Here’s what we recommend to keep your lenses scratch-free.

How to Avoid Scratching Your Lenses

Use a Protective Case

Using a sturdy eyeglass case will prolong the life of your lenses. No matter what kind of glasses you wear — standard, sunglasses, bifocal — you’ll want to protect them.

Be sure to choose a hard case with a soft inner lining and always have one on hand, either in your purse, backpack, or car.

When placing the glasses in their case, make sure the lenses are facing downwards, as this can reduce the risk of them being scratched. Additionally, avoid putting anything else in the case along with the glasses, especially sharp or metal objects.

Choose Anti-Scratch Lenses

Although no lenses are completely scratch-proof, there are certain coatings that can be added to the front and back of your lenses to make them more scratch resistant. Many lenses already come with this option, but sometimes it’s an optional addition. Anti-scratch coatings are particularly helpful for children’s glasses.

Remove Your Glasses Carefully

Handle your glasses by the temples (arms) and not the rims. This way, your fingers avoid the frame and lens area altogether, reducing the chance of inadvertently scratching them. Additionally, holding them by the temples with both hands ensures a better grip, so you’ll be less likely to drop them.

Set Them Down Properly

Never put glasses down with the lenses facing downward, unless it’s into a lens case. If you need to put them down and don’t have a case, rest them with the temples open and upside down — glasses tend to be more stable in this position.

Avoid placing them in a place where they’ll be easily knocked over or splashed on, like near a sink. Setting them down in the same place consistently will also reduce your risk of losing them.

Use the Right Lens Cleaner

It’s all too common for people to wipe their glasses with their clothing or other abrasive material. Doing so can scratch the lenses, especially if they’re dry.

Always clean your lenses with a soft microfiber cloth and specialized lens cleaning solution, items your optometrist’s office can provide.

When to Visit Your Optometrist

Unfortunately, it’s impossible to completely prevent your lenses from ever becoming scratched over their lifetime. Once they are scratched, there is little that can be done to repair the lenses. Most of the time the lenses need to be replaced.

At James Tracey Eye Care, we offer a wide array of frames and lenses, so you’re sure to find a pair to suit your eyes and needs.

Frequently Asked Questions with James Sinoway O.D.

Q: Can you request lenses made from glass? Is glass still used for lenses?

  • A: Yes. Opticians still sometimes use glass for lenses. However, glass is not used very often because they aren’t as safe. If these glass lenses breaks, they can shatters into many pieces and can injure the eye. Glass lenses are much heavier than plastic lenses, so they can make your eyeglasses less comfortable to wear.

Q: Can a coating be added to eyeglasses to protect them from further scratches?

  • A: A protective coating can’t be added to a lens after it’s scratched. The coating is applied when the lens is manufactured and can’t be put on later.

Why You Should Trust Your Optical Over Online Stores

We won’t argue with you – online shopping can be very easy and convenient. Without budging from the sofa, you can browse a variety of eyeglasses and click to buy. But plenty of risks lurk in every purchase you make from an online optical! Let’s compare the dangers and disadvantages of choosing new frames from a website versus the benefits of buying eyeglasses from our reliable optical in Midtown and Midland Park.

Cons of Buying Eyeglasses Online

  • The whole shopping experience is impersonal. No caring optician or eye care staff will listen to your visual requirements and lifestyle preferences to recommend the best, most reliable eyeglasses options.
  • You can’t ask an optician for a first-hand opinion of how you look
  • There’s no eye doctor to check that the fit of your frames is optimal; you’re on your own, left guessing about the right bridge span or pupillary distance.
  • Many optical stores have special deals with eyeglasses manufacturers, which enables you to receive rebates and discounts that are only available locally. Often, this makes your final cost less expensive.
  • Not all optical websites accept vision insurance.
  • Many studies show that over 50% of eyeglasses bought online were crafted with the wrong prescription or fit.

Pros of Purchasing Eyeglasses from Our Optical in Midtown and Midland Park

In our friendly local office, we strive to fulfill each customer’s vision needs, eye health requirements and sense of style. Even if your frames become your most favorite fashion accessory, they still need to give you sharp and comfortable vision. Our optical staff will assess your vision in your new eyeglasses, as well as how they fit on your face. Our goal is not simply to make a sale – it is to ensure that your new eyewear flatters your appearance and maximizes your clear and healthy eyesight.
