Back To Learning With Trivex


As kids go “back to learning” this Fall, many aspects of their lives have changed – including the school schedule and learning structure. More than ever, parents are looking for the best supplies, resources and tools for a successful school year. This includes finding eyewear that meets the specific needs of kids’ eyes, including durability, optical quality and protection – from impact, from harsh cleaners and chemicals and from UV and harmful blue light.

Trivex® lenses are an ideal choice for kids. Trivex is a urethane-based pre-polymer originally developed for the military as “transparent armor,” PPG Industries refined the technology for the optical industry in 2002 and named it Trivex, due to its three main performance properties: superior optics, ultra-lightweight and extreme strength.

The lens’s superior clarity is a product of its Abbe value. Trivex material has an Abbe value of 43-45, compared to polycarbonate at 29-31 and high index at 32-41. Trivex’s light weight is due to the material’s specific gravity. Trivex was engineered to be the lightest material, with a specific gravity of 1.11g/cm3. Lastly, lenses made with Trivex material can pass some of the optical industry’s highest standards for impact resistance,  and able to withstand the demands of kids’ active lifestyles.

COMMENTARY: WHY FACE MASKS CAN CAUSE DRY EYES AND WHAT YOU CAN DO TO PREVENT IT - By Lyndon Jones, University of Waterloo Special to Global News 
"[...] Face masks significantly reduce the spread of air outwards from the mouth and nose. However, exhaled air still needs to disperse; when a mask sits loosely against the face the likely route is upwards. This forces a stream of air over the surface of the eye, creating conditions that accelerate the evaporation of the tear film, like a steady breeze blowing over damp skin.

People who wear glasses are well aware of this, shown by the annoying lens fogging that often occurs when breathing under a mask.

When masks are worn for extended periods, this repeated evaporation may lead to dry spots on the ocular surface. Similar effects have been reported with continuous positive airway pressure (CPAP) masks that are used to treat sleep apnea. Eye dryness may also result when face masks are taped to seal the top edge, if that interferes with the eyelids’ natural movement, preventing full blinks. Incomplete blinking can cause the tear film to become less stable.

The OAC and OOA partnered on an advertising campaign that brings a little humour at a time we could all use some while informing the public that Opticians are OPEN and ready to help with their visual needs.

The advertising campaign includes a full page ad in the Horizon Toronto delivered to over 100,000 households in the Toronto area and 186 – 5 second spots on the largest wrap-around screen in Canada, located in Dundas Square in Toronto.

We will also be sharing the campaign through our social media channels – FEEL FREE TO SHARE on your business or personal pages!

What is cortical/cerebral visual impairment (CVI)?
Cortical visual impairment (CVI) is a decreased visual response due to a neurological problem affecting the visual part of the brain. Typically, a child with CVI has a normal eye exam or has an eye condition that cannot account for the abnormal visual behavior. Children with CVI display characteristic behaviors. It is one of the most frequent causes of visual impairment in children from developed countries.

How does vision work in CVI?
The eye structure in CVI is usually normal. The eye takes a normal picture of the object and sends the message to the brain. The message is not properly processed or integrated because of the abnormal brain function.

Damage to the posterior visual pathways results in characteristics visual behaviors depending upon which of the visual centers or association areas is involved. Damage to the optic tracts and radiations can result in abnormalities of the visual field (blind spots). Continue Reading...
