Tint Matters

Sunglasses

The tint of your sunglasses may seem like just a fashion preference, but did you know the tint you choose can also cater to your visual needs? The lens tint color you choose can determine how much visible light reaches your eyes.  Some tint colors improve contrast and color, while other tints may reduce both.  Quality prescription sun wear also protects your eyes from 99-100% of harmful ultraviolet radiation (UV-A and UV-B).

Generally, a gray or smoke lens tint is the most popular.  This shade reduces glare and does not distort colors. Gray is considered a general-purpose tint, and it best used when true color perception is most important. However, depending on your visual needs, other lens tints can offer benefits that are more specific.

Brown or amber tints provide contrast and minimize eyestrain.  These colors are ideal for high-glare sports like boating, skiing and snowboarding. For everyday use, brown or amber tints are excellent for driving.

For improved contrast in low-light conditions, a green tint is a good choice. This shade also reduces eyestrain in bright light, making it a popular multipurpose tint for daily wear.

Yellow and orange tints also provide excellent contrast in low-light conditions and are great to wear on overcast days. Additionally, this tint improves depth perception, making it an excellent choice for specialty lenses for sports like shooting.

You can enhance your lens tints by choosing polarized lenses. Polarization reduces reflected glare and protects your eyes from UV light, making it ideal for bright, sunny days. Check out Oakley’s guide to lens tints below before purchasing your next pair of sunglasses.

Why is my contact lens prescription a different strength than my glasses prescription?

shutterstock_226192324

Many contact wearers notice that the numbers on their contact lens prescription are different from the numbers on their glasses prescriptions. While some patients may think this is a mistake, there is a very simple explanation: distance.

The distance at which a corrective lens sits from the eye causes a notable difference in the strength of the prescription. This can easily be demonstrated by taking one’s glasses and extending them further away from the surface of the eye. If you have a nearsighted prescription, you will notice the power of the lens becomes weaker as you move it further away, and a farsighted prescription becomes stronger as you move it further away. Because of this, it is important that glasses prescriptions be tested at a similar distance to where a frame sits from a patient’s eye. During an eye exam, your doctor uses a phoropter to present multiple lens options at approximately 12 millimeters from the surface of the eyes.

When fitting contact lenses, the prescription must be adjusted, because contacts are placed directly on the eye, which is 12 millimeters closer than eyeglass lenses.  For nearsighted prescriptions, this means that the minus power of the contact will need to be weaker than in a glasses prescription. For farsighted prescriptions, it means the plus power of the contact will need to be stronger than in a glasses prescription. This difference varies depending on the strength of the prescription and only affects prescriptions over four diopters.

How to Have Healthier Eyes in 2015

We promise this resolution is easy!

We promise this resolution is easy!

Now that the New Year is under way, many people are working on their New Year’s resolutions. You may be working on getting fit, getting organized or getting your finances in order, but there is one easy resolution you probably forgot about: taking better care of your eyes. By making a few minor changes, you will be crossing this resolution off your list in no time.

 

  1. Schedule a yearly eye exam

A yearly eye exam is the first step to better eye health and it is essential to catching any early signs of eye disease. Many feel if they are seeing well, an eye exam is not necessary. This is not true, because many eye diseases do not show symptoms until it is too late. In addition, annual eye exams can alert your doctor to changes in your overall health.

  1. Wear your sunglasses

Sunglasses are not just a fashion statement, nor are they just for people who need prescription sunglasses. Your shades help to shield your eyes from UV radiation, which can contribute to cataracts, macular degeneration, and cancers of the eye. They can also protect your eyes from particles in the air.

  1. Follow your contact lenses’ directions

For those who wear contact lenses, you can drastically improve your eye health by simply following the directions for your contact lenses. Most people wear their contact lenses longer than what is recommended by their eye doctor every day. By following your optometrist’s recommendations, you can drastically reduce discomfort and risk of infections from over-wearing your contact lenses. Many contact lens wearers fail to replace their contacts on the schedule prescribed. Wearing your contact lenses past the replacement date makes you much more vulnerable to eye infections and permanent scarring of the cornea. If you’re running low on your contacts, make sure you have a current prescription and order new ones ASAP. 

By following these three simple steps, you will be able to cross this resolution off your list. These minor changes will not only lead to healthier eyes, but a healthier you.

Is online shopping affecting your eyes?

Now that holiday shopping is in full force, online shopping can be good for your wallet but bad for your eyes. Excessive near vision tasks, such as working on a computer, can cause strain on the focusing system of the eyes, causing eye fatigue, blurred vision and headaches. Electronic devices, such as computer monitors, mobile phones and tablets, emit high-frequency UV rays known as blue light. Studies show blue light can irritate the eye, cause damage to the retina, and disrupt sleep cycles.

If you spend time in front of a digital device, your eye doctor can help combat the effects of blue light. Glasses with specially manufactured lens coatings that help block blue light and reduce glare can significantly improve computer vision. With the proper eyewear, you can have healthier, more comfortable eyes. Talk to your eye care professional about how computer glasses can improve and protect your vision.

The truth about over-the-counter reading glasses

reading glasses

Around age forty, many people begin to have trouble seeing to read. Many people are tempted to try over-the-counter reading glasses. While these glasses may work for some people, they have their limitations. Over-the-counter reading glasses provide the exact same prescription in both lenses, which most people do not have. Also, they provide no correction for astigmatism, which is very common. Prescription reading glasses from your eye doctor are able to correct your prescription precisely. They can also give you multiple focal distances all in one pair. Therefore, you would be able to focus on your computer monitor and focus to read a book all with one pair of glasses. Over-the-counter reading glasses, on the other hand can only focus at one point, causing you to have to carry multiple pairs of glasses.

For proper reading glasses that fit your exact prescription, visit your eye doctor or schedule an appointment online.

Safety glasses and tool time: Prevent power tool eye injuries

safety glasses prevent power tool eye injury

Although warnings are often written all over power tools, it can never be stated too often how important it is to wear safety glasses while using them. It is all too common to see injuries in the eye doctor’s office from power tool accidents. We often find metallic foreign bodies in the cornea as a result of cutting or grinding metal without safety glasses. If pieces of metal or wood penetrate the eye, the eye can be lost. If they are just embedded in the cornea, they can be removed at the eye doctor’s office. However, they most often scar and can permanently affect vision.

Don’t worry, astigmatism is not a disease!

Astigmatism Diagram

Many times people hear that they have astigmatism and think it’s some sort of eye disease. This is not the case. Astigmatism is an optical or refractive disorder, similar to near sightedness and far sightedness. Astigmatism occurs when the cornea or lens of the eye has two different curvatures, similar to a football rather than a baseball. Having two different curvatures causes it to have two different powers, and it bends light through the eye differently. This causes a distortion that can be corrected by wearing glasses or contact lenses with two different curvatures that counteract the curvatures of the eye.

Customization: Clubs and glasses

By Dr. Christopher Jordan

customized eye glasses

Soon my teenager will be custom fitted for golf clubs. His game is coming along nicely and off-the-shelf clubs now limit his performance. The clubs will be fitted for his height, lie angle, swing speed and flex. The weight of his driver will be fitted to the nearest five-gram increment. And there will be custom degrees of loft to maximize distance. Even the golf ball will be selected for blend of distance, feel and workability. All of this will be done to maximize performance.

Certainly off-the-shelf glasses, like golf clubs, can be serviceable. However, serviceable is far from maximum performance. Consider online glasses, for example. While Rx and PD are considered, A dimension, B dimension, ED, face form, geometric center, lens material, lens craftsmanship, pantoscopic tilt, and well-fit frames are left wanting.

Consider distance through near progressives at a typical desktop computer work station. These will likely require head tilting, head turning, and will generally have focusing issues and digital eye strain (see previous blogs on blue light). A computer progressive with blue blocking glare free yields the better performance.

Soon my son will be on to better golf shots and better scores through custom fit technology. And I will inherit his off-the-shelf clubs. But not for long! This cost-to-benefit analysis is a no-brainer. Our patients testify the same when they customize their glasses. Visit your eye care professional soon to inquire.

Are Trivex lenses for you?

Photo of Trivex lenses
Trivex®  is a relatively new lens material that’s been available to the optical industry for a few years now. It’s an excellent choice because it’s clearer than a polycarbonate lens. It allows the eyes to see with more definition and less optical aberrations. Trivex®  is also a harder material and is incredibly light. This strength provides more structural integrity for the glasses, especially for thinner or nonexistent frames, and more impact resistance for eye safety. The lightweight nature allows for more comfort.
If you have questions about Trivex® or other lens options, call or visit your nearest Rinkov Eyecare Centers location.

7 Tips for First-Time Bifocal Lens Wearers

Bifocal Lenses

Is it time for you to start wearing bifocal lenses? We understand they can take some getting used to, so we’ve compiled a list of tips that will help ease your transition to bifocal lenses:

  1. Understand what situations you want to use your glasses for and express this during your eye exam. There are many different types of bifocal lenses and knowing what you will use them for allows us to prescribe the best lens for you.
  2. Choosing the right frame can make all the difference. You want to make sure your frame allows enough room for you to comfortably look through the different focal points of the lens.
  3. Be sure your frames stay properly adjusted. If the lenses become misaligned with your eyes, your vision will vary greatly.
  4. Always point your nose toward what you want to focus on. Looking out of the side of your lens will often cause distortion.
  5. Keep your lenses clean and scratch free. Imperfections in the lens can cause significant blur.
  6. Realize that using a bifocal will be different than a single vision lens. Your eyes and brain will need time to adapt.
  7. Stick with your new glasses. Switching between different prescriptions can cause your eyes to have a much harder time adapting.

If you have any questions about your bifocal lenses, call or visit your nearest Rinkov Eyecare Centers location, and our eye doctors or opticians will be more than happy to help!
