Dry Eye

Consistent lubrication is necessary for maintaining the health of ocular surface and for providing clear vision. Dry Eye syndrome (DES) is a condition in which there is insufficient lubrication either due to inadequate tear supply or poor quality of tears. Dry Eye syndrome is a chronic inflammatory condition and must be treated aggressively.

Risk Factors:

✓ Computer/hand held device use.

✓ Old age: Tear production decreases as you get older

✓ Being a woman: condition is more common in woman (2:1), especially when they experience hormonal changes due to menopause, pregnancy and the use of contraceptives.

✓ Diet low in Vit-A

✓ Extended/improper use of contact lenses.


✓ Irritated, red eye

✓ Gritty feeling or feeling of something in the eyes

✓ Excess watering

✓ Scratchy/itchy eyes

✓ Burning eyes

✓ Advance Dry Eye can damage the front surface of the eye and impair vision.

Depending on the severity of the condition, treatment could vary from conservative management with warm compresses and ocular surface lubricants to prescription eye drops and ointments to decrease inflammation. Call 905-766- 3721 to schedule a Dry Eye Consult!

What does 20/20 Eye Care do Different??

✓ At 20/20 Eye Care, we employ state of the art instrumentation to quantify and monitor any improvement overtime in the symptoms.

✓ At 20/20 Eye Care, we listen closely to our patients visual concerns, analyze their daily living activities to assess the demand on their visual system. We understand that not all dry eyes are the same and hence they cannot be treated the same way.

✓ At 20/20 Eye Care, our Comprehensive eye exam includes in depth analysis of the quality and quantity of tears produced by the eyes with special dyes and state of the art instrumentation.

✓ Assessment of eyelid gland, cornea and conjunctiva

✓ Assessment of eyelid structure and blink dynamics.

✓ Analysis of the results, patient education and discussion of treatment and/or lifestyle changes.


Computer Vision Syndrome

Computer vision syndrome (CVS) aka. Digital Eye Strain describes a group of eye related issues that result from prolonged use of computers and hand held devices (tablets, cell phone, e-reader).

Risk Factors:
Viewing digital screens for extended periods, poor lightning , Glare on the digital screen Improper viewing distances, poor seating posture, uncorrected vision problems. Symptoms are directly related to the amount of time spent looking at a digital screen.

✓ CVS affects about 90% of the people who spend three hours or more a day at computer.

✓ CVS affects 90% college students b/w ages 18 and 25.

✓ Headache

✓ Blurred vision

✓ Asthenopia aka. Eyestrain

✓ Neck and shoulder pain

✓ Red, teary eye

✓ Difficulty refocusing the eyes.

✓ Dry eye

Eyestrain is responsible for majority of the symptoms of CVS. A Comprehensive eye exam with emphasis on eye focusing, eye movement, visual requirement and refraction is required.

In some cases, individuals who do not generally wear eye glasses for their daily routine may benefit from eye glasses prescribed for computer use. Patients with eye focusing, movement or coordination issue causing CVS, may benefit from Vision Therapy.

✓ Treating ocular surface dryness with taking frequent Breaks (20-20- 20 Rule) and Blinking often.

✓ Using Anti-Glare Screen on computers.

✓ Using Anti-Reflective coating on your lenses.

✓ Using Blue-Block coating on your lenses. Blue-violet light has been shown to cause maximum retinal cell death. Over time, our eyes are exposed to various sources that emit this blue violet light including sunlight, tablets, TV’s computers and smart phones etc. It is essential to have blue block coating put onto your lenses.

✓ Using anti- UV coating: UV light causes damage to the eye, particularly the cornea and the lens. It can augment the growth of cataracts, pinguecula and ptrygium etc. Anti UV coating is essential to screen out the harmful effects of UV rays.

✓ Lightning: proper lightning is required when doing near work to avoid glare. Replace the light bulbs in the desk lamp s with bulbs of lower wattage.
