Health Tip – How often should you see the Eye Doctor?

Our schedules are so busy and so many things are going on that I bet it has been ages since you’ve seen the eye doctor.

The exceptions, of course, are those who have serious eye changes. But I bet, even the majority of you have waited too long to set up an appointment with your Optometrist.

The eyes are very complex organ system and can be the first signs that a serious medical issue is happening. If you’ve experience a loss of vision, change in vision, double vision, eye pain, serious eye redness, and a host of other eye related symptoms. It is probably time that you bite the bullet and schedule an appointment with your eye doctor.

Diseases such as glaucoma, diabetes, Multiple sclerosis, retinal detachment, and several other diseases can be seen as changes in the eye.

Factors that Determine how often you should see an Eye Doctor

1.)     Symptoms that alarm you or your family

2.)     Age – the older you get, the more often you need to be seen

3.)     Eye Health – If you are often getting infections, vision changes, or a change to your prescription – you should be seen more often.

4.)     Family history – If your family has a history of some of the more serious eye medical issues or diabetes – you should be seen more often.

When should Children see the Eye Doctor?

Children should have some sort of eye exam early in their lives. This will often be done by your primary care physician. They may be looking at a wall evaluation piece with shapes and such. If obvious vision changes are noted – then a referral to an eye doctor may be in order.

Beginning at age 3 – children should be checked every one to two years by their pediatricians.

If younger, school aged children start to develop eye changes – they need to be seen quickly. Development  and educational advancement is lost quickly when a child is unable to see the board quickly.

I first went to the Eye doctor in 1st grade and got my first pair of glasses. I had complained about not seeing things on the board. It happened x 3 weeks in and it took me another 3 months to catch up with the rest of the students.

Adolescents

They should be seen every two years unless they wear glasses or contacts or if an Eye Doctor specifically wants to see them sooner.

Many eye injuries occur at this age. Even if the symptoms improve – it may, in some cases, be helpful to visit the eye doctor after serious eye injuries.

Adults – Ages 20 to 40

If you wear eyeglass or contact lenses – you need to be seen yearly.

If normal vision continues with an adult who doesn’t wear corrective lenses – they can usually wait two to three years in-between visits.

If a change occurs to the vision, an appointment should be made quickly following the change.

If you have normal vision but have diabetes – you should be checked yearly.  This may also be the case for other medical issues.

Adults – Over the age of 40

At age 40 – most adults should have a eye screening. Things such as cataracts, glaucoma, macular degeneration and many other eye conditions should be evaluated. Age causes several eye changes and/or damage.

If you have no corrective lenses and a normal Age 40 check. You can be seen every two years.

If there are problems or you wear corrective lenses – you still must be checked yearly.

Another age check should be done around age 60-65.  From that point – depending on what is already been happening for the last several decades, specialized or specific guidelines will be given.

It is safe to say that yearly checks are recommended for some.

Overall

Eye examinations are vital and important to maintaining a good eye health and really a good overall health. Losing your eyesight when it could have been preventable is a devastating problem. Simple eye examinations can really be beneficial.

Don’t lose sight of the need to be checked for something, even if you are healthy. A slight modification early can really prevent a serious problem down the road.

Learn More about Night Blindness

Imagine driving a car down a busy interstate or inside a tunnel, when suddenly the lights and your vision go from bad to horrible. It becomes almost impossible to correct changes to the steering wheel, see the lines, and avoid any and all oncoming traffic.  Night blindness is close enough to that, when it goes from dusk to dark and your vision suddenly goes from good to horrible.

Night Blindness when described in the medical community becomes the important and authoritative word of Nyctalopia.   Night blindness can be its own condition, relatively little, or a symptom of another condition.  It may be something that starts from birth or something that you acquire over time.  In reality, it is the inability for your eyes to adapt to the light change when going from some light to little or almost no light.

Let’s look at some of the possible causes of Night Blindness.

1.)     Congenital 

–          This means that it’s a condition from birth
–          X-linked night blindness affects the Rod cells in the eye

2.)    Eye injury

3.)    Malnutrition

–          The cause for this is often a lack of vitamin A.
–          There are other nutrition related causes.

4.)    Retinitis Pigmentosa

–          This is a disorder that affects one of the two types of cells
–          In this case – the rod cells are affected
–          They lose their ability to respond to light.

5.)    Myopia

–          This is nearsightedness and when this becomes worse
–          The eye is spending so much effort to become better or focus
–          It then loses the ability to see or differentiate light.

 6.)    Glaucoma Medications

–          These types of medication often constrict the pupil
–          A constricted pupil allows less light to enter
–          This affects the overall ability to see lights

7.)     Cataracts

–          This is a condition where clouding occurs on the lens of the eye
–          This also affect the ability for light to enter into the eye.
–          They can be potentially blinding if not treated.

Diagnosis

Diagnosis of night blindness can be simple and complicated at the same time. You will be asked several questions to ensure that some other issue isn’t present. Of course, if it is Glaucoma medications or Myopia, treatment may be simpler than you think.

You must consider a few things in your mind. Try to understand when you are affected by night blindness?  Is it somethimes or all the time?  Are there other vision changes that you are experiencing. Any family history of Diabetes?

Eye Exam

You will probably need a full eye exam. They will check vision, pupillary changes with light, a light that is shined in your eye to look at the vessels of the eye and overall lens. They will probably check your ability to see colors as well.

Treatment

Unfortunately, not all night blindness can be treated. If it is a symptom of a condition and that condition can be treated, then that’s a good thing. Things like Vitamin A deficiency, Myopia, and certain medications can be altered.  But Retinitis pigmentosa and Birth defects can not be treated and avoidance of driving in the dark is recommended.
