Curing Nearsightedness with Corrective Lens. The Good and the Bad

“From now on, he needs to wear corrective lens.” Period. That’s all the optometrist told my mom during my eye examination.

If you are diagnosed with nearsightedness, this will be the first thing your optometrist will recommend.

They will prescribe you a set of glasses and sent you off.

What he forgot to mention is that if you keep wearing it, you will be wearing it forever.

He also forgot to say that, it will get worse year after year.

It always sadden me to see children with glasses. As their eyes are still developing, wearing corrective lenses inhibit their eyes from growing properly.

It makes their eyes grow weak and strengthen their addiction towards eyeglasses.

How Corrective Lens Work?

Corrective lenses are just pieces of glass and they correct your eyesight artificially. In a myopic eye , the light usually lands in front of the retina.

Minus lens (also known as negative lens) which is concave (thinner in the middle, thicker at the edges) in shape is usually prescribed to nearsighted people.

Nearsightedness Corrected With Minus Lens

Clear vision is achieved when concave shape help to bend the rays of light outwards and the light converge further and reach the retina instead of in front of the retina.

By now the intelligent you would have realized that they do not fix our eye problems. They can only fix your eyesight temporarily by refracting light differently into your eyes.


Glasses And Contacts Do Not Correct The Problem

"The use of compensatory lenses (glasses and contacts) to treat or neutralize the symptoms does not correct the problem. The current education and training of eye care practitioners discourages preventive and remedial treatment."

Gottlieb, Journal of Optometry and Visual Development, 1982

Even though we gain instant clarity, nothing about our eyes has changed. The eye muscles are still weak and our eyeballs are still elongated. And the more you wear it, the worse your eyes will become. Read on for studies on the detrimental nature of corrective lens.

“Single-vision minus lenses for full-time use produce accommodative insufficiency associated with additional symptoms until the patient gets used to the lens. This is usually accompanied by a further increase in myopia and the cycle begins anew.”

M.H. Birnbaum, Review of Optometry, 1973

Many times our corrective lens are over prescribed. Remember the sudden headache and giddiness when you first wear your glasses? Those are the signs but your optometrist would tell you that you will get use to it.

"There are frequently ignored patterns of addiction to minus lenses. The typical prescription tends to overpower and fatigue the visual system and what is often a transitory condition becomes a lifelong situation which is likely to deteriorate with time."

S. Gallop, Journal of Behavioral Optometry ,1994

Little wonders on why we always feel tired when we put on the lenses constantly. As if that is not bad enough, there’s another problem with minus lens. They increase near point stress.




Minus Lenses Increase Near Point Stress

"Minus lenses are the most common approach, yet the least likely to prevent further myopic progression. Unfortunately, they increase the near point stress that is associated with progression."

B. May, Optometric Extension Program Foundation, 1983

As you have learn from the article on nearsightedness, near point stress is one of the greatest culprit of myopia.

We ought to do everything we can to keep them contained. Corrective lens are static while our eyes are not.

Minus lenses are made to accommodate 20 feet visual. Which means that you are only supposed to use it for seeing distant objects.

Anything below 20 feet start causing near point stress.

As myopes, our close visual acuity is actually perfect.

Using glasses for close up work creates a additional near point stress. It’s like using a hammer to hit a fly. Your eyes become fatigued easily.

In addition, our eye movement is limited within the frame of the glasses.

Further limiting the usage our eye muscles therefore weakening them. In the end, our eyes got adapted to the space provided and weaken the extrinsic ocular muscles.


Regain Your Eye Muscles Back

Winning

In order to reverse the damage, we must start removing those corrective lens now. Use them only on times where it is absolutely necessary.

Times where you have to handle dangerous machinery, shooting, driving, checking out your dating partner... you get the idea.

In addition, like all muscles, we have to do some rehabilitation work to regain our strength.

There is where eye exercises come to the rescue!

Eye exercises are a set of activities that aim to strengthen your eye muscles and increase their flexibility.

These in turn helps you to increase eyesight and slows down eye deterioration.


Pros: Instant effect, can be cheap, look smart(?)
Cons: Inconvenient, uncomfortable, can be expensive, myopia progression

Now we will move on to one of the less common ways to improve myopia. The Orthokeratology approach.
