The Optometry clinic in PolyU is a teaching facility for Optometry students who receive their clinical training in the last two years of their undergraduate program in the School of Optometry. The service of the clinic is open to the public and it has been serving the society for over 35 years. Apart from teaching, the clinic also supports clinical research and acts as an important clinical resource of eye care in Hong Kong.
Many people may have an impression that an optometrist is the one who refracts your eyes in an optical shop. In fact, the scope of work of optometrists is far more than that. The School of Optometry in The Hong Kong Polytechnic University trains optometrists to carry out comprehensive eye examination which includes the evaluation of:
Vision is the ability of the eye to resolve details of objects at different distances. Refractive errors refer to short-sightedness, far sightedness, astigmatism and presbyopia.
Visual functions include binocular vision or coordination between the two eyes; color vision; eye movement; pupil reflexes and visual field screening, etc. The results of these tests are highly useful to the final judgment on the management of an individual’s ocular conditions.
Finally, the optometrist is also capable of detecting ocular problems such as dry eye, cataract, glaucoma and retinal problems, etc. through a detailed assessment on the ocular health of the patient.
Upon completion of all the examinations, an optometrist will discuss the findings and provide recommendations for the patient to tackle his/her visual and ocular problems.Care for the Environment
In Optometry practice, it is common to capture the photo of the eye as clinical record. This helps to monitor the changes and progress of some ocular conditions. Such photos are also an important teaching material for Optometry education.
In the past, 135mm camera system was used to take photos of the external (cornea/lens) and internal (retina) regions of the eye. As a result, huge amount of negatives/slides/print-outs had to be kept by the clinic (approximately 12,000 print-outs were produced in a year). Moreover, it usually took a few days to develop the negatives and photos. This consumed a lot of physical space, manpower, chemicals and at the same time produced a lot of chemical wastes.
By Year 2000, digital camera system replaced the traditional film-based camera in which all photos could be saved in electronic format. At the early stage of such development, hard copy print-out of the digital photo was still unavoidable as the capture station was a standalone device and therefore sharing of electronic document was not feasible.
Thanks to the latest information technology, the Optometry Clinic in PolyU is now applying DICOM (Digital Imaging and Communications in Medicine) technology to store and retrieve digital ocular images. After taking the picture of the eye, the capture station will send the images to the DICOM gateway and the images are saved in the DICOM server. The optometrist will then go back to the examination room and retrieve and display the photo on the monitor for explanation to the patient as well as teaching the Optometry students. After using this electronic platform, the Optometry Clinic reduces hard copy printing of clinical photos by 80% in volume. In 2014 for example, nearly 10,000 print-outs were saved.
To further protect the environment, the Optometry Clinic also started two new green measures in 2015:
Frankly speaking, there is no full-stop to environmental protection; the clinic is now planning for 100% paperless operation in the coming years. In addition to the electronic medical records, the Optometry Clinic is now exploring other patient communications channels such as SMS/email reminder, Near Field Communication (NFC) receipt/report/payment, etc.
By applying the cutting edge information technology, the Optometry Clinic will continue to strike for a better ‘green’ practice and we hope that the Optometry students can be trained to be an eye care professional with environmental protection sense.

On 12 March 2015, the Environmental Protection Department (EPD) announced the approval of PolyU’s application for subsidy from the Pilot Green Transport Fund. The subsidy will be used for the trial operation of one electric light bus within a period of 24 months.
With the aim of improving roadside air quality, reducing carbon emissions and combating global climate change, the Government has set up a $300 million Pilot Green Transport Fund to support the trial of green and innovative technologies applicable to the public transport sector and goods vehicles since 2011.
You can find more information about the Fund from EPD’s website at http://goo.gl/7w3HMS.
With the coordination among Campus Sustainability Committee, Facilities Management Office and Health, Safety and Environment Office, new signage has rolled out on PolyU campus to introduce energy saving escalators and eco-block.Signage of Energy Saving Escalators
The energy saving escalators will run at normal speed if passenger is detected and at crawling speed or stop if no passenger is detected for a specific period of time. Pay attention to these green installations when you visit Phase 8 (Block Z) and Jockey Club Innovation Tower.Signage of Eco-Block
Eco-block, an environmentally friendly construction material, has been widely used on PolyU Campus. Introduction of eco-block does not only reduce the disposal of waste, but also conserves natural resources, such as river sand, and helps to remove air pollutants on campus. You can find the signage to learn more about the eco-block at i) footpath behind Core A and next to Jogging Track; ii) footpath along Yuk Choi Road opposite to MN Wing; and iii) vehicular access behind Core Q.
As one of the oldest trees on campus, the Khaya senegalensis in front of the library has guarded the district for over 40 years.
Khaya senegalensis is an evergreen tree. Flowering shortly occurs before or early in the rainy season and the fruit apparently remains on the tree throughout the dry season. In addition to being an ornamental, we can use its wood as construction material; the leaves as animal feed; and bark, resin and leaves as medicine.

Being one of six individual halls in the Student Halls of Residence (Homantin), Green Hall has been endeavoring to promote environmental culture. A reusable items collection campaign co-organized with the Chinese Mainland Student Association (CMSA) was held during the mass check-out period in May 2015 to collect the unwanted items such as books and cooking utensils. The collected items will either be distributed or sold to new hall residents at the beginning of the next academic year.
To promote green practices in orientation camp and encourage students to play smart, Health, Safety and Environment Office in collaboration with Student Affairs Office have prepared the “Green O’ Camp Information Kit” for all O’ Camp student organizers. It provides easy-to-follow tips in areas on organizing green O’ camps, such as clothing, food and venue management. The full information kit can be found at http://www.polyu.edu.hk/greencampus/en/green-tips/green-info-kit.html.
In addition, a collection house has been planned to place at the podium level outside Communal Building to collect surplus O' Camp souvenirs in late August until early October this year.
Moreover, PolyU supports the “Green! O Camp Project” organized by Friends of the Earth (HK). This year, the project theme is “Green Bottle O Camp”. All O’Camp organizers and participants are encouraged to bring their own reusable water bottles to reduce the waste generation from disposable plastic bottles. You can find more information about the campaign from the dedicated website at http://www.foe.org.hk/GOC/eng/index.html.
To echo the initiatives of green O’ Camp and foster the campus-wide culture of sustainability, The Green Society, a green student organization under PolyU Students' Union, has been actively adding the green elements to their own O’ Camp and involved in the “Green! O Camp Project” organized by the Friends of the Earth (HK). To follow their status updates, you are most welcome to like The Green Society’s Facebook page at https://www.facebook.com/PolyUGreenSociety.
PolyU has pledged to maintain an average indoor temperature between 24to 26°C during the months from June to September 2015 in supporting the Energy Saving Charter on Indoor Temperature 2015 advocated by the HKSAR Government with an aim of reducing electricity consumption for air-conditioning.
In Hong Kong, 90% of electricity is consumed by buildings which contribute 60% of greenhouse gas emission and air-conditioning accounts for a majority of building energy consumption. Energy conservation has long been a commitment and being a key indicator in the context of PolyU campus sustainability. Thus, keeping the indoor air-conditioning temperature within an efficient range could assist in reducing greenhouse gas emissions and promote energy conservation on campus.
More details of the Charter can be found from the dedicated website at http://www.energysaving.gov.hk/indoortemperature/2015/en/.

To promote the culture of cherishing our food and have a green Mid-Autumn Festival, Campus Sustainability Committee and Health, Safety and Environment Office will organize a green mooncake soap workshop in Mid-Autumn Festival this year. This workshop will let participants make soap with food waste (such as rice chaffs and coffee ground), and then re-shape them into mooncake. Participants will have a chance to take home their hand-made mooncake soaps.
To enhance the public awareness about energy saving and wise use of air-conditioning, Green Sense will once again launched the “Hong Kong No Air Con Night” this year on 25 September. Since the launch of the first “Hong Kong No Air Con Night” in 2010, the campaign had encouraged over 315,000 households to join the event accumulated from 2010 to 2014.
The proposed “No Air Con Night” at homes is a large-scale activity for motivating the whole society to participate in energy saving. All household units and university hall students are invited to switch off their air-conditioners for at least one night on 25 September 2015, suggested from 7pm to 7am the next day. All household units and university hall students are also encouraged to stop using the air con at night afterwards.Details
Over the years, various world-wide environmental and sustainability-related days have been established to raise public awareness on different environmental, social and ecological issues:
The International Day for the Preservation of the Ozone Layer, proclaimed by the United Nations General Assembly in 1994, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer. Please visit the United Nations website for more information at http://www.un.org/en/events/ozoneday/index.shtml.
The Clean Up the World Weekend is held on the 3rd weekend in September each year, focusing on public attention on global community concerns for the environment and how each individual can make a positive contribution to a cleaner and healthier world. In 2015, Clean Up the World Weekend will be held from 18 to 20 September 2015. Please visit the Clean Up the World website for more information at http://www.cleanuptheworld.org/en/Activities/clean-up-the-world-weekend.html.

On 19 May 2015, PolyU received good class certificates of Indoor Air Quality (IAQ) Certification Scheme 2014, which has been organized by the Environmental Protection Department (EPD) since 2003 to promote and commend good IAQ management practice. This year, PolyU also received a special award as one of the ten organizations with the highest participation rates in terms of floor area.
Over the years, PolyU endeavors to provide a pleasant indoor air environment for all staff and students. Certified buildings with good class certificates are listed below.
You can find more information about the scheme from the dedicated website at http://www.iaq.gov.hk/index_eng.asp.
On 17 June 2015, PolyU received the Certificate of Gold Award for the School Sector in Yan Oi Tong Plastic Recycling Partnership Scheme 2014/15, marking our second consecutive year as the award recipient, to recognize our efforts on supporting and promoting plastic recycling.
Over the years, PolyU has set up a wide variety of recycling bins on campus to facilitate source separation and recycling. You are encouraged to separate the recyclables and put them into recycling bins to reduce the amount of waste sent to landfill. However, the best option is still to avoid generating waste.
The collected plastics on campus are handled by Yan Oi Tong EcoPark Plastic Resources Recycling Centre (YOTPRRC), which is funded by the Environment and Conservation Fund (ECF). ECF was set up under the Environment and Conservation Fund Ordinance (Cap. 450) in 1994 to support educational, research, and other projects and activities in relation to environmental and conservation matters. The locations of recycling bins on PolyU campus can be obtained from Facilities Management Office’s website at http://www.polyu.edu.hk/fmo/eMap/recycle_bin_locator.html.
The Hong Kong first energy saving blueprint was unveiled by Environment Bureau with the goal of cutting the amount of energy for every unit of wealth created by 40% by 2025 and reducing the electricity consumption in Government buildings by 5% by 2020. As close to 90% of Hong Kong's electricity is consumed in buildings, green building development becomes one of priority tasks in the plan. It is proposed all new public housings and Government buildings have to reach at least BEAM Plus Gold rating and encourages private building to adopt the same benchmark. The Government will drive the energy saving in both public and private sectors through a combination of educational, social, economic and regulatory means. You can find the full blueprint from Environment Bureau’s website at http://www.enb.gov.hk/sites/default/files/pdf/EnergySavingPlanEn.pdf.
The Environmental Protection Department released the 2012 greenhouse gas (GHG) inventory for Hong Kong. GHG mainly contributes to global warming because it absorbs infrared radiation and trap heat in atmosphere.
According to the latest inventory, there was a slight increase of GHG emissions from 2011 to 2012 by 0.7% or 300 kilotonnes CO2-e. Electricity generation was the major emission source, accounting for 68.2% of total city emissions. The per capita GHG emission was around 6 tonnes CO2-e, equivalent to removing about 260 units of trees in one year Note. It reminds us to take steps forward to reduce the greenhouse gas emissions in our daily life.
Details of the greenhouse gas inventory in Hong Kong can be found from Environmental Protection Department’s website at http://www.epd.gov.hk/epd/english/climate_change/resources.html.
Note: Based on the Environmental Protection Department’s guideline, the removal factor of one tree per year is 23 kilograms CO2-e. The figure is applicable to all trees commonly found in Hong Kong which are able to reach at least 5 metres in height.
Proclaimed by the United Nations, every 5th of June is the World Environment Day (WED), a day to remind us of the environmental issues we are facing. “Seven Billion Dreams. One Planet. Consume with Care” was the theme this year. Evidence shows that people are consuming far more natural resources than what our Earth can sustainably provide. “Consume with care” means living within planetary boundaries to ensure a healthy future where our dreams can be realized. To learn more about the World Environment Day, please visit the dedicated website at http://www.unep.org/wed/.
To echo with the World Environment Day, Hong Kong Green Council has launched “Hong Kong Green Day 2015” on the same day. A series of activities were organized with the theme of “Go Green, Act Green”. PolyU is one of the supporting organizations for this meaningful event. You can find more information from the website at http://www.greenday.hk or Facebook page at https://www.facebook.com/greenday.hk.
Sustainable seafood refers to the seafood that is either wild caught or farmed in a manner that meets the demands of today while not damaging a fishery’s ability to provide the same function to future generations Note. According to the World Wide Fund for Nature (WWF)’s consumer survey revealed in late 2014, a primary challenge for consumers is to locate and purchase sustainable seafood.
To encourage the public to adopt sustainable seafood in their meals, WWF-Hong Kong has launched the “Sustainable Seafood Week” during the period from 27 June to 5 July 2015. Over 100 restaurants used sustainable seafood to prepare Ocean Friendly Menus. In addition, a series of activities were organized, such as Sustainable Seafood Photo Competition and Panda Flash Mob. You can find more about the “Sustainable Seafood Week” from WWF’s website at http://goo.gl/Rp3x3R.
Also, WWF-Hong Kong published Sustainable Seafood Guide with the aim of helping individuals and businesses choose sustainable seafood and avoid unsustainable seafood products. The Guide covers seafood species that can easily be found in local wet markets, supermarkets and frozen food shops. You can find the full guideline from WWF’s website at http://goo.gl/0lhNS0.
Note: The definition of sustainable seafood was provided by WWF-Hong Kong at http://goo.gl/Rp3x3R.
