                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 Do All of These Options Mean!?

Posted by Courtney DeFord on Mon, Feb 15, 2016 @ 15:02 PM

Do you ever go to your local eye care provider and when ordering your new glasses, you have no idea what anything is that they're asking you to order? Well I can tell you from personal experience that before I was educated about what all of the different options were, I would always just order the cheapest thing possible. I didn't think that the other upgrades were really worth paying the extra money for.

In some cases, I was right, it was not worth it for me, but there are others that think the same way that I always did, when in fact, they would really benefit from some of the options that are available to them.

Blue Light and What it Does to You

Posted by Courtney DeFord on Tue, Feb 02, 2016 @ 15:02 PM


                Ever wonder why you’re always feeling tired? Or after working in an office all day, your eyes are killing you? This is because your body is feeling the effects of blue light, causing you to have eye strain.

                Light is made up from various wavelengths that are all under different “categories” on the electromagnetic spectrum. Blue light is a part of the only spectrum that humans are sensitive to: Visible Light. Other colors on this spectrum are violet, indigo, green, yellow, orange, and red.

                According to www.bluelightexposed.com, it has been suggested by studies that prolonged exposure to blue light could cause long-term damage to one’s eyes. In addition to causing things like retinal damage or macular degeneration, blue light also has an effect on our sleep cycles, but we will get to that later.

                Sources of blue light are the sun, digital screens, electronic screens, LED lights, and fluorescent lights. When you’re outside, the blue light wavelengths from the sun meet with the air particles, causing the blue light to disperse, which is what makes the sky look blue.

                Naturally, our eyes weren’t built for protecting themselves against the blue light that is given off by the sun. It would only make sense that they are also not able to protect themselves against devices such as the smart phone and the blue light that is given off from other similar devices.

                An increasing problem that people are having is how blue light effects their sleeping pattern, throwing the body’s circadian rhythm or “time clock” out of whack. Studies have shown that blue light slows the production of the hormone melatonin, which is produced by our bodies to help aid in sleeping. Melatonin helps to ease the mind and invites you to fall asleep. This would mean that those nights that you lay in bed and scroll through your social media before going to sleep is actually hindering your ability to get a sound night’s rest.

                In closing, although blue light can elevate your mood and awareness, having long-term, repeated exposure can harm your eyes. Take some time away from the electronic devices that you use every day and focus on the natural light that surrounds you or speak with your eyecare provider about getting special lenses that help to block out the harmful blue light being emitted from your electronics.

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

Posted by Kaitlyn Miller on Mon, Aug 25, 2014 @ 16:08 PM

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.

Maximize UV Eye Protection

Posted by Kaitlyn Miller on Fri, Jun 06, 2014 @ 08:06 AM


Can eyes get sunburned?

While everyone knows that skin requires protection from UV radiation, many people wonder – can eyes get sunburned? According to the American Optometric Association, the eyes can get sunburned (photokeratitis) just like skin, and can affect vision and harm the eyes. These UV-A and UV-B rays can have serious long- and short-term effects and can lead to an increased risk of skin cancer.

                                                 UV eye protection Eye protection from UV radiation block backside UV reflection

People with eye sunburn experience symptoms including a gritty feeling in the eyes, dry and red eyes, excessive tearing and intense sensitivity to light. Although this condition is rarely permanent, long-term exposure to the sun without proper eye protection can be harmful. Sunburned eyes are not the only concern — the Skin Cancer Foundation warns against cancer on the eyelid, a condition that accounts for 5 to 10 percent of all skin cancers.

There’s more to sunglasses than looking cool !

Sun is usually associated with pleasure and well being. But a good protection is mandatory to enjoy only the best part of the sun. 

You are probably aware that UV radiation damages the skin… and therefore you protect yourself with a quality sun screen. But did you know that sun exposure can also damage your eyes?

Less than 10% of wearers worldwide are aware of sunrays dangers on the eyes… But UV rays are very harmful to the eyes. They are invisible but can generate short term or long term damages. 

On the short term:  UV rays can cause discomfort and reversible diseases like blurred images, inflammations, photokeratitis.

Eyes that are unprotected from UV Rays - Danger to Visual Health |  Eyes protected with Sunwear Lenses - Optimal Protection

On a longest term, UV rays can generate:

- Premature Age-Related Macular Degeneration (AMD):  this is the leading (preventable) cause of severe and irreversible loss of vision.  

- Cataracts : this is the number 1 cause of blindness, accounting for 16 million people worldwide; over 3 million of these are probably caused by excessive UV rays exposure.(1)

- UV rays can also damage the skin causing sunburns, sunspots, premature appearance of wrinkles. In the worst cases, it can also lead to cancers (melanoma & carcinoma).

Warning!  80% of a person’s lifetime UV exposure is received before the age of 18 (1).  So it is critical to protect childrens’ eyes with quality sun glasses.

50% E-SPF

Each year 3 million people go blind from prolonged UV exposure. 

Think about protecting your eyes with quality sunglasses to preserve your sight.

All sun lenses do not offer the same UV protection.

The Sun, UV Radiation and Your Eyes

Posted by Kaitlyn Miller on Tue, Jun 03, 2014 @ 10:06 AM

Woman Sunglasses Hat OPTKeep an Eye on Ultraviolet Safety:

Eye medical doctors caution us that too much exposure to UV light raises the risks of eye diseases, including cataract, growths on the eye, and cancer. Strong exposure to snow reflection can also quickly cause painful damage called snow blindness.

Growths on the eye, such as pterygium, can show up in our teens or twenties, especially in surfers, skiers, fishermen, farmers, or anyone who spends long hours under the mid-day sun or in the UV-intense conditions found near rivers, oceans, and mountains.

Diseases like cataract and eye cancers can take many years to develop, but each time we're out in the sun without protection we could be adding damage that adds to our risks for these serious disorders. Babies and kids need to wear hats and sunglasses for this very reason. People of all ages should take precautions whenever they are outdoors.

Follow these tips to protect your eyes from the sun all year long:

    • Sun damage to eyes can occur anytime during the year, not just in the summertime, so be sure to wear UV-blocking sunglasses and broad-brimmed hats whenever you're outside.
    • Don't be fooled by clouds: the sun's rays can pass through haze and thin clouds.
    • Never look directly at the sun. Looking directly at the sun at any time, including during an eclipse, can lead to solar retinopathy, which is damage to the eye's retina from solar radiation.
    • Don't forget the kids and older family members: everyone is at risk, including children and senior citizens. Protect their eyes with hats and sunglasses.

UV Light: Good in Moderation for a Good Night's Sleep

As we sleep, our eyes enjoy continuous lubrication. During sleep the eyes also clear out irritants such as dust, allergens or smoke that may have accumulated during the day. Some research suggests that light-sensitive cells in the eye are important to our ability to regulate wake-sleep cycles. This may be more critical as we age, when more people have problems with insomnia. While it's important that we protect our eyes from overexposure to UV light, our eyes also need minimal exposure to natural light every day to help maintain normal sleep-wake cycles.

Time Outdoors May Prevent Nearsightedness in Kids

Research shows that children who spend more time outside exposed to daylight may reduce their risk of developing nearsightedness. So not only is exercise great for eye health, but now it seem that getting that exercise while outside may be additionally beneficial. Taking your children outside to play may not only help lower their risk for nearsightedness, but will also teach them good habits for a lifetime of eye health".

Eschenbach's New Telescope Mounting Adapter with Adhesive Eliminates Need for Drilling

Posted by Kaitlyn Miller on Mon, May 19, 2014 @ 16:05 PM

Eschenbach's new Telescope Mounting adapter #1627-03 allows select monocular telescopes to be mounted to eye wear without drilling into the lens. The Adapter is threaded on the inside and will accommodate any of Eshenbach’s Galilean monocular telescopes- #1621, #1622, or #1623. It features a strong adhesive ring that affixes to the lens surface and it includes thin foam layer between the adapter and the adhesive ring to allow it to make a secure seal.

The Telescope Mounting adapter is suitable for single vision spectacle lenses with a front Plano base curve of up to =+12.00 diopters. The mounting process is fairly straight forward: mark the front of the lens where you want the telescope mounted, copy the mark on the back of the lens, thoroughly clean the front side of the lens, screw the telescope into the Adapter, remove the protective paper over the adhesive ring on the Adapter and then affix the Adapter with the telescope onto the outside of the lens. Find out more at www.eschenbach.com.
