                Ever wonder about what your baby is seeing?  Is their vision as good as a baby as it is when they grow up? Trying to figure out what someone else is seeing is difficult, but then to throw in the fact that they cannot even tell you what they are seeing just adds to the equation. This is why taking care of your child’s eyes is something that a parent needs to be pro-active about and not re-active!

                When in the womb, a baby’s eye structure begins forming early on during the pregnancy, at only seven weeks! Around week ten, the eyelids form and will stay shut through week twenty-eight. During this time, the eyebrows and eyelashes form and the child is able to see light through their eyelids. Once the eyelids and eyes are fully formed, the baby will be able to see light outside of the womb.

                Immediately after birth, a baby can only see about a foot in front of their face, but by three months they will be able to recognize familiar faces and follow objects in a 180 degree range! After about six months, the baby should be able to focus, see color, and have depth perception. This is when the parent should look into getting the baby their first eye exam. The doctor will be able to check to make sure that the baby is developing normally and whether they are near or far sighted, cross-eyed, or if they have a lazy eye.

                These days, most parents will take their babies into the doctor without any symptoms for check-ups, shots, etc., yet 24% of parents wait to take their child to the eye doctor until they see any symptoms. It is recommended that children have a minimum of three eye appointments by age six, think of all that can be missed by not having an eye appointment for SIX years!? Having vision issues can be a cause for children not to develop as quickly as other children and can also contribute to behavioral issues. In fact, 60% of students that were identified as “problem learners” have an undetected vision problem.

                The statistics surrounding visual health can be quite surprising, but it creates an awareness that we need to make sure that we are taking care of our eyes on a regular basis instead of waiting until there are symptoms of a problem. At Hi-Tech Optical, we truly care about your vision and the vision of your loved ones. We urge people to be pro-active and bring children in for a yearly eye exam with our Doctor, we have a large variety of frames for the whole family to choose from!

What are the Benefits of Copper, Orange, Amber/Yellow and Brown/Bronze Tints

benefits lens tints

Written by: Michael Eldridge August 21, 2014

Copper, orange, yellow/amber and brown/bronze lens tints make your environment appear brighter and are commonly used in low-light conditions. These lens tints block blue light and enhance contrast and depth perception making them helpful for overcast, hazy and foggy conditions.

Blue light, with its shorter wavelength, scatters easier than other colors and makes focusing more difficult. Removing blue light therefore improves sharpness and depth perception and reduces fatigue. Note: These lens tints do cause some degree of color distortion, though brown/bronze lenses do so considerably less than do yellow/amber or orange lenses.

Common users of copper, orange, yellow/amber and brown/bronze lens tints include baseball players, golfers, hunters and cyclists, as well as, those playing indoor sports and water sports. Individuals spending a considerable amount of time in front of a computer screen also find yellow/amber tints helpful because they reduce eye fatigue and strain by blocking blue light.

The specific lens tint – copper, orange, yellow/amber or brown/bronze – depends on individual preference and situation.

Recent studies are showing new uses for lens tints that block blue light, and the potential applications would have significant impact for many individuals. Consider the following:

  • Sleep problems – Studies show that excessive light, especially blue light given off by computer screens, televisions and ambient light in most homes, suppresses melatonin. Melatonin, our natural sleep hormone, helps us get to sleep. For those struggling falling asleep, wearing lenses that block blue light for an hour before bed may prevent melatonin suppression, thereby allowing individuals to fall asleep more quickly and easily.

  • Bipolar disorder– Preliminary research shows that blocking blue light may help stabilize mood for individuals suffering from some forms of bipolar disorder. According to Dr. Jim Phelps, this “dark therapy” works basically in the opposite way as light therapy for depression.

  • Macular degeneration – Excessive blue light from sunlight may be one cause of age-related macular degeneration. This eye-disorder exists at the leading cause of blindness in the elderly.

    Based on this research, consider wearing copper, orange, yellow/amber or brown/bronze lens tints if you struggle falling asleep, have been diagnosed with bipolar disorder, or want to prevent age-related macular degeneration.

    While copper lenses block blue light better than the other lenses mentioned, they may be too dark for many to wear inside. Yellow/amber, orange and brown/bronze lenses still block enough blue light without the dimming effect to still produce some of the same benefits mentioned above.

    More research is needed, but exposure to blue light clearly has significant impact. In addition to the potential effects mentioned above, blue light may also increase cancer risk as well as have possible connections to diabetes and obesity.

    Because of its harmful potential, in addition to wearing lens tints that block blue light, consider also replacing night lights with dim, red lights to reduce exposure to blue light when trying to sleep, avoiding television and computer screens an hour or two before bed, and getting more natural light during the day to help regulate the body’s natural rhythms.

    Finding ways to regulate exposure to blue light may not only help you sleep better, preserve eyesight and stabilize mood, it may also go a long way in benefiting overall wellness and longevity. Take time today to assess your situation to determine if blue light may be having a significant impact on your health.

Sunglasses Help Protect Your Eyes

Posted by Cristie Wineland on Mon, Jul 02, 2012 @ 11:07 AM

Do you make an effort to wear sunglasses when you’re outdoors or driving? Some people own multiple pairs of sunglasses depending on styles and protection. Everyone should own at least one pair. Even if your one pair is not the sturdiest of material, something is better than nothing at all. Eye protection from the sun’s damaging rays is greatly important. Sunglasses help filter light as well as protect your eyes from harmful Ultraviolet rays.

Be a smart shopper when it comes time to purchase a pair of sunglasses. Choose a pair that is comfortable, close-fitting, doesn’t distort colors, reduces glare and protects against 99-100% of UV rays. Avoid sunglasses that say “cosmetic” or do not have labels.

***Be Sure to Read Labels***
Look for labels that read: Block 99-100% of UV-A and UV-B rays.

These two types of UV rays can cause eye problems. Let’s refresh your memory on what UV-A and UV-B rays are. UV-A has a long wavelength and they penetrate your skin more deeply. Watch out because UV-A rays can go through windows, lightweight clothing, and even your car windshield. UV-A hurts your central vision; part of the retina at the back of the eye. UV-B has a short wavelength and they are responsible for tanning your skin, but they also cause sunburn. UV-B rays are the main culprit when it comes to skin cancer. These rays also go through windows, and it doesn't matter if it's cloudy. UV-B is mostly absorbed by the front part of the eye and may cause more damage than UV-A. 

If you already own a pair of sunglasses and are concerned about if they are UV protected you can take them to a local eyewear shop and have them tested. For example Hi-Tech Optical has a machine called a UV MeterSunglasses that measures the UV light-rays passing through a lens. The machine reads back a number of how much protection your lenses have. Most optical shops will not charge for this service so if you come across one that does, check somewhere else.

Another way to protect your eyes is to wear sunglasses that have coatings on the lenses. A UV Protective coating can easily be added to your lenses although most lenses already have it on them. An Anti-Reflective coating helps to reduce glare, reflections and halos around lights. Or you can purchase specific lenses such as: Photochromic or Polarized lenses to protect your eyes from harmful UV rays. Photochromic lenses adjust their level of darkness based on the amount of UV light hitting them. You may know this type of lens as the trademark name Transitions™.  Polarized lenses are the best choice for protection and seeing clearly because the lenses take in light and filters it so it diminishes glare when you are looking at something.

 Now you know a little more about why sunglasses are important and why you should wear them. If you are curious on pricing for items such as: coatings, lenses, or even just frame styles give your local optical shop a call today. We would be happy to answer any questions you have about eyewear protection.
