Common eye conditions

The following information gives a brief overview of some of the common eye conditions people can suffer from.  If you suffer from any eye problems, or, for early detection of any of the below conditions – visit Vision Care Centre – Langley, or call to book an eye exam today to have a professional consultation with one our Optometrists who will be happy to explain any eye condition in detail.


 

Myopia (Near-sightedness)

Myopia is a very common eye condition.  Objects in the distance appear more blurred, while closer objects are clearer.  This is because either the power of the eye is too strong, or that the eye itself is too long.  Either way, the image of the object you see is formed before it reaches the retina and so is blurred.  Myopia is easily corrected with <a href="http://www.bcvisioncare best task manager software.com/eye-wear.html”>glasses or contact lenses.

Hyperopia (Far-sightedness)

Hyperopia is another very common eye condition.  Objects in the distance appear generally clearer, while closer objects are blurred.  This is because either the eye is not powerful enough, or the eye itself is too short.  Either way, the image of the object you see is formed after it reaches the retina and so is blurred.  Hyperopic people can increase the power of their eyes by accommodating and making the image clear, although this becomes more difficult as you get older or if you do a lot of concentrated work.  Hyperopia is easily corrected with glasses or contact lenses.

Astigmatism

Astigmatism is an eye condition that can occur in conjunction with myopia, hyperopia, or on its own.  Astigmatism occurs when the front of the eye (cornea) is not perfectly spherical (often described as ‘football shaped’).  It causes the image of the object you see to be focused at two different points and so is blurred.  Astigmatism is easily corrected using glassesor contact lenses.

Presbyopia

Presbyopia is caused when the eye gradually loses its ability to see objects up close.  It happens to everybody from around the age of 40 and gradually continues from then on.  The main reason for it occurring is that the lens in the eye becomes less flexible and harder to change shape, and so makes close objects look blurred.  As the changes happen so gradually, the effects are often not noticed immediately.  But over time, headaches may occur and reading may become more difficult – unless you hold a book further from you.   Presbyopia is easily corrected using reading, progressive, or bifocal glasses. Contact lenses are now also available.

Amblyopia / Lazy Eye

Amblyopia is when 1 eye has poorer vision than the other perhaps due to anisometropia (assymetrical prescription), uncorrected prescription, or strabismus (eye turn) causing the connection between the eye and the brain to deteriorate project management tools.  To prevent permanent vision loss it is imperative to give vision correction, vision therapy, patch treatment, or surgery before the age of 7/8 years of age as it is difficult to retrieve vision after this age even with glasses.

Strabismus

Strabismus usually starts in early childhood.  This misalignment of the eye(s) either in/out/up/down should be treated to prevent amblyopia (lazy eye).  Treatment includes glasses, contact lenses, prisms, vision therapy or surgery.

Dry eye

Dry eye is a condition where either the eye does not produce enough tears, or the tears do not lubricate the eyes sufficiently. This makes the eyes feel uncomfortable, gritty, burning, and sometimes makes the white of the eyes appear very red.  Dry eye can affect anyone at any time, although it is more common as we get older and as a side effect from medication.  Confusingly one common symptom is the eyes watering excessively, especially in windy weather.  Often, symptoms can be relieved by treating the glands in the eyelids and by using artificial tears to lubricate the eyes better, although long term dry eye may need further investigation to rule out any general health problems.

Styes

A stye is an infection on the edge of the eyelid that appears slightly red, swollen and feels tender.  Vision is not affected.  Usually styes heal on their own, however a hot compress can help, and if recurring then antibiotic ointment can be used.

Cataracts

Cataract is a term used to describe the gradual aging and cloudiness of the lens in the eye software task management.  When we are born the lens is perfectly clear and supple, but as we age the lens becomes more opaque and less flexible.  This has the effect of us needing more light in order to see as we get older, and objects generally appearing a little hazier or sensation of a film over the eyes. Sometimes the lens can become so opaque that it affects the vision, and causes problems such as glare (especially at night). Initially the vision can be improved by new eyeglasses but eventually a short surgical procedure will be required to replace the opaque natural lens with a clear artificial lens. There is evidence that suggests wearing UV protection outdoors; and a diet rich in vitamin A,C, E & selenium; avoidance of smoke, alcohol & pollution have preventative benefits.

Diabetes

Diabetes is caused when the body is unable to properly regulate the amount of glucose in the blood.  Symptoms can be very mild and so can be very difficult to spot.  Long term poor control of diabetes can affect the eyes by causing retinal blood vessels to leak.  The blood vessels become more prone to bleeding, causing risk to the sight of the eye.  Generally speaking, the earlier any diabetic retinopathy is noticed in the eyes the better the outcome after any treatment.  People with diabetes are also more prone to cataract and macular changes causing a reduction in vision.  Because of this, diabetic patients are advised to have regular eye exams.  At Vision Care these are covered with a BC care card yearly.

Glaucoma

Glaucoma is the name given to a group of diseases which cause progressive gradual degeneration of the optic nerve and eventually blindness.  Glaucoma is caused by a number of factors which can include high internal pressure of the eye, poor blood flow to the eye, over 35 years of age, and genetic factors.  Glaucoma affects the peripheral vision, and often goes unnoticed by the patient.  Very rarely, glaucoma can affect people very suddenly making them feel sick and causing pain to the eyes – in these cases immediate urgent assessment is advised.  If left untreated, vision loss cannot be restored only halted.  As there are usually no early warning signs, regular eye exams are crucial especially for over 35 year olds and people with a family history of glaucoma.

Macular Degeneration

Macular degeneration (or ARMD) affects the area of the retina (macula) that deals with sharp central vision.  It generally affects people over the age of 75, and causes deterioration in central vision. There are two main types; dry and wet. Dry macular degeneration is far more common, progresses slowly and affects the vision more mildly.  Wet macular degeneration is less common, but has far more drastic changes sometimes causing total loss of central vision in extreme cases.  Prevention is key as treatment is limited depending on the type.  Much research has been put into UV protection, nutrition, and dietary supplements such as Vitalux and PreserVision which contains vitamins A, C, E, zinc, lutein, zeaxanthin, & omega-3 to help delay ARMD.  These can be purchased at Vision Care Centre.

Floaters

Inside your eye, there is a watery jelly-like fluid called the vitreous.  Tiny specks in the vitreous swirl around as you move your eyes which are more noticeable on bright days or when looking at light coloured objects, e.g. a page of a book.  Most people notice floaters in their vision at some point in their lives.  Myopic people often notice them more, and they are more common with age.  Most of the time, these floaters are perfectly normal.  But if you suddenly notice a large increase in floaters, or notice any flashes of light, or even a shadow across your vision, you should book an eye exam as soon as possible because this may indicate a more serious problem such as a retinal detachment.

Caring for your Eyes

With conditions such as cataracts and macular degeneration on the rise, it is important to take precautions to help prevent damage.  During your eye examination your Optometrist will go through advice & precautions, and explain to you how diet & supplements can help preserve your eyesight for life.

  1. Have your eyes examined regularly.  Our eye exams are extremely thorough and can pick up eye conditions and other health problems.
  2. Eat plenty of fruit and vegetables.  Broccoli, spinach, sweetcorn, orange and yellow peppers, kiwi fruits, oranges and mangoes are all great sources of the substances lutein and zeaxanthin, which may help protect against some eye conditions.  If your busy lifestyle means your diet isn’t always as healthy as you’d like it to be, ask about eye-health supplements next time you’re in.
  3. Protect your eyes from the sun & indoor tanning beds.  Over-exposure to Ultraviolet (UV) rays can cause a number of problems, including cataracts, age-related macular degeneration, pingueculae, pterygium and certain lid cancers.  Nowadays there is an increase in UV penetration in our atmosphere even on a cloudy day. Often people forget that UV protection is just as important in water and snow environments.  In these environments, always wear sunglasses or UV Blocking eyewear which provide 100% UVA & UVB protection.
  4. Stop smoking. Smokers are up to three times more likely to develop cataracts than non-smokers – another good reason to quit.
  5. Take short, frequent breaks from the computer to prevent eyestrain and tiredness.  Even if you don’t get up, an ‘eye break’ – when you look away from the screen and focus on objects at varying distances will help.
  6. If you play a lot of sport, buy protective sports goggles to shield your eyes.  This is especially important if you’re keen on racquet sports; squash is the main cause of serious eye injuries.  We carry Rx and non-Rx sportswear at Vision Care.
  7. Eye injuries at home are common.  Always wear safety goggles to avoid injuries caused by flying wood chips or metal shards.  If your job requires you to wear protective eyewear enquire about the OVP (Occupation Vision Plan) Program which we participate in.  We work with the BCAO and certain Employers to provide their workers with low cost or no-charge safety glasses.  Talk to your employer to see if you qualify.
  8. If you get dust or grit in your eye, don’t rub it.  Pull the upper eyelid down over the lower lid and blink frequently to help the lower lashes and tears sweep and wash away the foreign object.  If you have difficulty, come in to see us or your local emergency department if we are closed.
  9. If you wear contact lenses, regular aftercare check-ups are vital to ensure your lenses remain comfortable and your eyes stay healthy.  At Vision Care unlimited aftercare is built into the price of the contact lenses..
  10. If you notice any changes in your vision, pain in or around your eyes or if you keep getting headaches, book an appointment to see an Optometrist at Vision Care.
