Signs Your Child Needs Glasses

When your child is of a very young age, it can be difficult to tell if they are having difficulty with their vision or are simply developing strange habits. It can be especially difficult to tell if your child is having vision difficulty if they have yet to learn how to speak. Because of this, we have gathered some common vision impairment signs.

  1.     Getting too close to objects. This is usually a more common concern for parents. If your child is sitting too close to the T.V. or holding objects close up to their face in order to see, they could be near sighted.
  2.     Are constantly squinting or closing an eye. These are other common signs of vision impairment. If your child is doing this, it can be because they are trying to reduce blurred vision or they are trying to cover the poorer vision. These are signs of amblyopia, strabismus or cataract.
  3.     Tilt their head to see. When children constantly tilt their heads when looking at object, it could be to help reduce double vision. If this is the case, they could have an eye muscle imbalance, also known as strabismus.
  4.     Are constantly rubbing eyes. This can be a sign of tiredness or eye fatigue. If this is constantly occurring, it could be a sign of allergic conjunctivitis.
  5.     Teary eyes. This is common for children whose eyelids don’t completely close when they’re asleep. This can cause dry eyes and vision impairment.

If any of these signs are common or visible in your child, schedule an eye exam to help correct their vision and help them see more clearly!


Different Types of Lenses

When you first go to purchase glasses, chances are you don’t really think about the multiple varieties of lenses that are out there nor their technical terms. There are many technical terms for glasses that correct different eye conditions, as well as the ones used for different situations.

Single Vision Lenses:

These are the most common lenses used. They are used to correct nearsightedness, farsightedness and astigmatism.

Bifocal and Trifocal:

These lenses have multiple focal points for close-up and far away vision. Lenses like these usually have a line splitting the focal points.

Progressive Lenses:

Just like the bifocal and trifocal lenses, progressive lenses have multiple focal points (intermediate, close and far away points). Unlike bifocals, however, these do not have outlines that determine the focal points, which makes the transition more natural.

Anti-Reflective (AR):

These lenses are designed to cancel out the reflection off the lens surface. This helps to eliminate eye strain when looking at screens and help with night vision.

Scratch Resistant:

These lenses are exactly that, scratch resistant. This helps decrease the amounts of scratches that may affect the eyes.


These lenses can be made thinner and flatter than regular lenses in order to use a larger portion of the surface because they have various curvatures.

High-Index Plastic:

These types of lenses are usually made for those who need strong prescription. However, these are lighter and thinner than the old school lenses, which were very thick.


These are special lenses for those who work in industries that require eye protection. They are lightweight, thin and impact-resistant.


For those who play sports, these are the lenses you should be using. Just like the trivex lenses, these are also impact-resistant and can also be used to protect eyes in tough work.


These lenses are known as the transition lenses that transition from clear to dark. They can be made as either glass or plastic. They help reduce eyestrains while transitioning from indoor lighting to outside light.

Choices for Contact Lenses

Italian Architect, Mathematician and Inventor Leonardo daVinci (1452-1519) produced the first known sketches that suggested the optics of the human eye could be altered by placing the cornea directly in contact with water. More than 350 years later those ideas were researched and studied to examine how the production of corrective lenses could conform to the front surface of the eye. In 2016, contact lenses are a common choice for people who would like clear vision without the bother of glasses to tote around all day. Since the inception of contact lenses to the vision field, they have come a long way. Let’s examine the types of contact lenses available and what might be right for you.

According to the American Academy of Ophthalmology there are two general types of contact lenses: hard and soft.

  • Hard Lenses – The hard lenses most commonly used today are rigid, gas-permeable lenses (RGP for short). They are made of plastics and other materials such as silicone or fluoropolymers. Hard lenses hold their shape, yet allow the free flow of oxygen through the lenses to the cornea. RGP lenses may be the best choice when the cornea has enough astigmatism (is shaped like an egg instead of an orange); a soft lens will not provide sharp vision. They may also be preferable when a person has allergies or tends to form protein deposits on his or her contacts.
  • Soft Lenses – Soft lenses are the choice of most contact lens wearers. These lenses are comfortable and come in many versions.

In addition there are sub-types of contact lenses that can be chosen based upon your lifestyle of preference for care. For example there are daily wear lenses, which are removed nightly and are replaced on an individualized schedule, and then there are extended wear lenses, which are worn overnight but are removed at least weekly for thorough cleaning and disinfection. Disposable-wear lenses are more expensive, but convenient. They are removed nightly and replaced on a daily, weekly, biweekly, or monthly basis. Talk to your eye doctor about the style that would be right for your life.


Contact Lens Care

If you are one of the millions of Americans who wear contact lenses, then you know the overwhelming feeling of figuring out the hundreds of products displayed in the lens care aisle in the supermarket or drugstore.  To avoid eye infections, you know that you need to care for your lenses properly.  Following a careful and clean regime with your contacts is extremely important for the health of your eyes.  Let’s review some guidelines for the safe handling of contact lenses.

  1. Always wash your hands with soap and water before putting in or taking out your contacts.  Dry your hands on a clean, lint-free towel.
  2. Avoid wetting lenses with tap water or saliva from your mouth.  Saliva is not a sterile environment.
  3. The FDA recommends that you rub the lens in the palm of your hand with a few drops of solution, even if you are using a “no-rub” product.
  4. Following the recommendations of your eye doctor, use a solution to remove loosened debris.
  5. Place the lenses in a care case and fill with fresh solution.  Do not top off with old solution.
  6. Do not touch the tip of your solution bottle to any surface to avoid contamination.
  7. Do not transfer solution to travel size cases to avoid contamination as well.
  8. If you use hair spray, use it before you put in your contacts. It’s also a good idea to keep your fingernails short and smooth to avoid damaging your lenses or scratching the eye.
  9. Put on make up after you put in contacts so you don’t get any on your lenses. Take out contact lenses before you remove makeup for the same reason.
  10. Clean you contact case with either sterile cleaning solution or hot tap water.
  11. Follow the regimen that your eye doctor set out for your specific type of contact lenses.  Do not change the regimen without approval to avoid getting infections.


Polarized Lenses Provide Great Benefits

Polarized lenses not only provide various visual benefits they also contribute to overall eye health and general safety.

Blinding glare can be hazardous while driving year round. Polarized lenses block glare, including dashboard & snow glare, and can greatly improve driver reaction time. Everyone is at risk of vision damage from harmful UV rays. Exposure to UV light can cause photokeratitis (welder’s flash), lead to cataracts and invoke premature macular degeneration. Polarized sun wear provides protection from both UVA & UVB rays.  Additionally, polarized lenses provide comfort, greater clarity, and truer color perception.

Photochromic “transition” Lenses

Photochromic, or “transition”, lenses darken when exposed to sunlight or ultraviolet (UV) light. Once the light source is removed (for example by walking indoors), the lenses will gradually return to their clear state. Indoors and at night, these lenses carry no tint making them as clear as ordinary lenses.

“Transition” lenses are available in gray and brown. Gray lenses transmit color evenly for true color recognition; brown improves contrast and depth perception. These lenses can also be made in almost any prescription and lens material.

Additionally, photochromic lenses block 100% of UV rays. This provides protection for everyone, especially children given that they receive 3 times the annual UV exposure as adults.
