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.

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.

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!

What’s all this I hear about blue light?

Blue light UV-C

Blue light is in the UV-C spectrum.

Blue light (UV-C) is any light with a wavelength between 380-500nm. Today we are exposed to more of this type of light than ever before due to our use of cell phones, tablets, computers, television screens and energy efficient LED light bulbs. Prolonged exposure to this light has been shown to cause change to the macula of the eye which may lead to possible macular degeneration. It has also been shown to suppress the secretion of melatonin in the body which can cause effects on a person’s circadian rhythms and may lead to an increased risk of depression.

gunnar computer glassesThere are currently lenses available that can help to block or reduce the amount of blue light transmission to the eye. These lens and coatings should be considered for anyone who is at risk of excessive exposure to blue light. This will have a soothing, less stress, less fatiguing effect on the eyes.

Reduce childhood nearsightedness by 50%

Reduce childhood nearsightedness

A new study that took place over a two year period of time shows promise for reducing the progression of myopia (nearsightedness) in kids by up to 50%. The technique used involves the fitting of a multifocal contact lens instead of the more traditional single vision lenses. Apparently with traditional contact lenses, the peripheral retinal receives a relative defocused image and sends a signal to the eye not to get longer (axial length). Multifocal contacts helps prevent this. Multifocal contacts, available in popular brands and materials, are well-tolerated by children. Visit your nearest Rinkov Eyecare Centers eye doctor for a consultation and details.

Warning: Beware of costume contact lenses

halloween contact lenses

It’s Halloween and many people are tempted to accentuate their costumes with cosmetic contact lenses. With a quick online search, a person can find many websites offering cosmetic contact lenses for sale, and many of them claim that no prescription is needed. This is untrue and unsafe. All contact lenses, whether vision correcting or cosmetic, are labeled as medical devices by the FDA and therefore require a doctor’s prescription. A prescription is required to ensure that the contact lens fits your eye correctly. An improperly fitting contact lens can cause injury and scarring of the cornea, which can result in permanently reduced vision or even blindness. Having “cool” contact lenses to go along with your costume is not worth the risk to your eyes and vision.

If you have any questions or think your contacts have scratched or scarred your eye, please call your closest Rinkov Eyecare Center immediately for attention.

BB guns and airsoft guns: A common cause of blindness

BB gun

Unfortunately there is a very common cause of blindness in children that could be easily prevented. Children report to emergency rooms quite frequently with BB gun injuries to their eyes. A BB will very easily destroy the eye and cause permanent blindness in that eye. This can be prevented  by parental supervision and by wearing protective shooting glasses made from impact-resistant polycarbonate lenses. Another common injury seen in resent times is eye injuries from airsoft guns. People are under the false impression that because airsoft pellets are made of plastic, they are safer. This is not true. The plastic projectile is travelling at such high velocity, that it can easily destroy an eye. Whether playing with a BB gun or an airsoft gun, a person should never point the gun at another person or animal. The shooter should select his or her target carefully, to avoid the projectile from ricocheting back at the shooter or toward others.

The proper way to instill eye drops

How to properly use eye drops

Instilling eye drops can be challenging for some people. Remember that it’s your eyes’ natural defense mechanism that causes you to blink when something is coming towards them.  Knowing a proper technique can allow for easier and safer insertion.

Step 1: Wash your hands.

Step 2: While looking up, pull down your lower eye lid using your non-dominant hand.

Step 3: Using your dominant hand, hold the eye drop bottle approximately half an inch away from your eye and squeeze the bottle to dispense one drop. Be careful not to allow the tip of the bottle to touch any part of your eye or eyelid, as this can cause a bacterial contamination.

Step 4: Release your lower lid and blink your eyes as needed.  Refrain from rubbing your eyes or wiping them with a tissue; this may cause less than optimal absorption of the eye drop.
