There are a couple of views many adhere to tenaciously with respect to spectacle wear, while some on the other hand seek clarifications to these myths. But what are these blurry sets of thesis, and how true are they?
Are refractive errors communicable? The answer is No; they aren’t. Myopia, hyperopia, and astigmatism cannot be transmitted physically from person to person, as they are not diseases; neither do they have disease vectors. They are simply lapses in the way light rays bend to reach the eye for us to perceive images clearly. Such errors can be compensated for with appropriate corrective lenses.
No one is too young to have a refractive error. As such, no one is too young to wear glasses (corrective or protective), provided one has a visual system which is either less optimally functional or in need of ocular protective/preventive aid.
Sunglasses aren’t just dark shades as some perceive, especially sunglasses with UV blocking agents. This set of sunglasses serve a whole lot of preventive functions to the eye, blocking off harmful Ultraviolet rays which cause cataracts and retinal degenerations that could lead to severe visual impairment or even total vision loss. Any pair of sunglasses void of this protective element should NEVER be worn, as such could cause more harm to the eye than good.
Spectacle wear doesn’t make one’s eye sink inwards or bulge out in any way really. Diverging lenses minify images while looking through them; and converging lenses on the other hand magnify images. So, what on-viewers see really (which makes them make this assumption) is a function of the lens’ optical property, not a change in the configuration of the eyes.
From about 40 years and above, a condition called Presbyopia sets in. This is observed as a difficulty in reading near prints with one’s distant spectacle correction in place, due to a gradual loss of elasticity of the crystalline lens in the eye. This is compensated for with the use of lens ‘‘Adds’’; and with increase in age, the ‘‘Adds’’ increase. Likewise, in high myopia, the length of the eyeball keeps increasing, requiring higher corrective lens powers. So, basically, it is the structures in the eyes that are changing. Lenses don’t cause any of these changes or deterioration in vision in any wise.
Can regular eye exercises keep one from needing glasses? No! They can’t. While eye exercises can help improve the functionality of the eye muscles, vision relies on the shape of the eyes and the health of the eye tissues, none of which can be appreciably altered with eye exercises.
Reading in dim illumination cannot worsen one’s vision. One will only end up straining one’s eyes and at some point could even attain dark adaptation. However, after such dark adaptation over a long period of time, one must not expose oneself immediately to a very bright light source, as it could bring about bleaching of the retina. The use of sunglasses, Polaroid lenses or adaptive lenses with such protective functions is recommended after such dark adaptation.
When one wears a wrong prescription, one could have headaches, dizziness, blurred vision or even double vision (diplopia). But these presentations would eventually fade out on discontinuation of such wrong prescriptions and the administration of the correct/appropriate spectacle prescriptions. So, wrong prescriptions do not damage the eyes as is widely thought. They bring about discomforts, which of course can be eliminated with the proper corrections in place.
Days are gone when eye wears had stereotypic presentations, lacking variety. In our present day, different brands and classes of frames and lenses exist to suit diverse persons, physiques, styles, occasions and purposes; and as such, you can find glasses that add class and sophistication to your look. You always can.

When you think about your favourite sights, what images do you see? The sunset from your porch, the radiant smiles of your children and grand children, the glimmer in your partner’s eyes as you dance together. Now, consider what it would be like if those crystal clear images were suddenly blurry, covered in a haze that dulls your world. Such is life with cataracts, a degenerative eye disease that clouds vision and may eventually lead to blindness.
Here are some recommendations for delaying and even preventing cataracts.
* Taste the rainbow. maintain a balanced diet, rich in antioxidants and vitamin C and E. consider incorporating these eye healthy foods and take multivitamins to ensure that you are always getting adequate nutrients, even if your diet gets a little off track.
* Maintain a healthy weight, diabetes and obesity can lead to cataracts. Reduce your risk by exercising regularly and eating healthy portions.
* Moderate your vices. Smoking and excessive alcohol can also contribute to the cause of cataracts. Limit your alcohol consumption and nix the cigarettes.
* Protect your eyes from the sun. Shield your eyes from harmful ultraviolet rays by wearing sunglasses with UV protection and wide brim hats.
Get an eye examination every year. A comprehensive eye examination will not only help detect early signs of cataracts but will also check for age related macular degeneration, glaucoma and other vision problems. Schedule your appointment today with HAVEN OPTICALS LTD.

Hurray, the yuletide is here again! It’s the season of celebration for families and friends marked with several memorable activities the world over. As always, preparations have begun in earnest for most people with the usual decorations that colour our streets, offices and houses making them look glamorous for the season. In the usual fashion, this yuletide would be laden with displays of Christmas trees, lights and its attendant decorations; gifts and presents, foods and drinks, fireworks, outings and activities to make the season worthwhile.
As we bask in the euphoria of the celebration of the yuletide, it is pertinent we remind ourselves of the safety of our eyes and indeed our health. Studies have shown that a significant amount of eye injuries happen during the festivities hence, the need to be cautious as we celebrate in this yuletide.
Here are a few tips for safe eyes during this yuletide:
Safe eyes are a possibility this yuletide if you can apply these simple but important tips during this yuletide celebration. However, if any eye injury or casualty is recorded, please seek prompt medical attention and visit your eye doctor.
Wishing you a happy yuletide celebration!

According to John F. Kennedy, “Children are the world’s most valuable resource and its best hope for the future.” Sadly, many children who perform poorly at school are wrongly labeled as learning disabled when indeed it is attributable to poor eye sight. These children are however not aware of how poor their vision is since that has been how they know the world to be. Children with undetected vision difficulties may have been programmed to fail educationally, athletically, socially and emotionally. Therefore, failure to identify and treat a vision problem early in school age children can lead to poor grades, low self-image and a negative school experience.
Oftentimes parents erroneously associate eye examination with eyeglasses or blindness thereby denying their children the benefit of a timely and professional eye examination. From my experience, many children that present to the hospital for eye related problems are mostly those identified by their observant teachers who notice certain abnormal visual habits displayed by these children in school. Quite sadly, they may have developed conditions like crossed eye, amblyopia among others which may not readily respond to routine treatment because of late presentation to the eye doctor.
Parents and guardians should watch out for certain abnormal appearances and visual habits that are red flags of poor vision in children. Below is a list of some of them:
APPEARANCE: On observing the child’s eyes and you notice that lids are crusted, red-rimmed, or swollen; styes (‘’boil”) occur frequently, eyes water or appear bloodshot, eyes are crossed or turned
BEHAVIOR: when a child holds work too close or too far, asks for special seating, seats very close to the television set, thrusts head forward to see distant objects, holds body tense when reading or looking at distant objects, frowns or squints when reading, attempts to brush away a blur, rubs eyes frequently, blinks continually when reading, tilts head or covers one eye.
COMPLAINTS: when a child complains of itchy eyes or sensitivity to light, images appear blurred or doubled, letters and lines run together, words seem to jump and frequent headaches.
PERFORMANCE IN ACADEMICS: when a child exhibits slowness in learning to read, short attention span, poor achievement demonstrated by reduced quality or quantity of work and slow rate of learning.
PHYSICAL ACTIVITY: when a child performs poorly at games, exhibits poor eye-muscle coordination, stumbles or trips over small objects
All these are strong indicators for a child to see an eye doctor. Early detection is key to ensuring good vision, healthy development and better learning experiences for children. A careful observation of children would not only encourage early discovery of those with visual needs, but would ensure they present early to their eye doctor which would increase the chances of improved vision of the children. However, pre-school eye screening and regular eye examination remain the best strategies for eliminating avoidable blindness in children and will guarantee them a visionary future.
