Computer vision syndrome is a complex of eye and vision problems related to near work performed on computers. It is characterized by visual symptoms like eyestrain, headache, blurred vision, and dry eyes that result from prolonged computer use. The pathophysiology involves extraocular mechanisms affecting muscles, accommodative mechanisms straining focus, and ocular surface mechanisms drying out eyes. Risk factors include aging, poor ergonomics, lighting, and underlying eye diseases. Treatment focuses on lubricating eyes, improving ergonomics, taking breaks, and managing underlying conditions. Prevention emphasizes modifying lighting and workstation setup, proper eye care, and short breaks to reduce visual demands of computer use.
This document discusses low vision, including its most common causes such as macular degeneration and diseases like diabetic retinopathy and glaucoma. It describes optical and non-optical devices that can help patients with low vision by improving their ability to see at distances, read print, and reduce issues like glare. The goal of low vision rehabilitation is to maintain and improve vision care for these patients and educate others, as disability does not mean an inability to live life, and devices can facilitate daily living.
A cataract is a clouding of the eye's natural lens that causes blurry or dim vision. Cataracts develop when the lens proteins become damaged over time due to aging, eye injuries, medical conditions, or other risk factors. Common symptoms include blurred vision, glare from lights, and frequent prescription changes. Cataract surgery removes the cloudy lens and replaces it with an artificial lens, restoring clear vision. Recovery requires following precautions like using eye drops as directed and avoiding irritants or strenuous activity.
This document discusses visual display units (VDUs) and their possible health effects. It describes the technologies behind cathode ray tube (CRT) monitors, liquid crystal display (LCD) monitors, and light emitting diode (LED) monitors. It also discusses asthenopia, or digital eye strain, which affects 40% of VDU users due to convergence and accommodation difficulties. Risk factors include ocular issues, personal factors like fatigue, and workstation factors like lighting, glare, and screen design. Proper lighting levels and positioning can help reduce glare and eye strain when working with visual display units.
An artificial retina called the Argus II has been approved by the FDA to help restore vision. It consists of an implanted microelectrode array on the retina and external components including a small video camera mounted on glasses. The camera captures images and wirelessly transmits them to the implant, which stimulates surviving retinal cells. While it provides a basic form of artificial vision, the technology is still limited and very expensive, though it offers hope to many suffering from blindness.
1) The document discusses how vision is important for winter sports and activities, as 85% of awareness comes from vision. It notes challenges with wearing glasses or contacts during winter sports.
2) It provides tips for those considering LASIK surgery for winter, including researching the procedure online, talking to those who had it, and consulting a qualified surgeon to determine candidacy.
3) LASIK has helped many reduce dependence on glasses and contacts, but it is important to thoroughly research the procedure and choose the best surgeon, as it is a medical procedure and not for everyone.
An eye gaze system uses eye tracking technology to measure where a person looks using sensors and cameras. It analyzes eye movements and point of gaze using image processing algorithms. Eye gaze systems have various uses in entertainment, aviation, and safety applications. They can be used to interact with video games, detect pilot fatigue, and diagnose medical conditions with high accuracy rates. However, eye gaze systems also have disadvantages like high costs, issues with some users' eyes, and potential for unintended eye movements.

A viewfinder is what photographers look through to compose and focus pictures. Optical viewfinders display around 90-95% of the image but LCD screens have advantages like convenience in bright light. Despite LCD benefits, pro photographers prefer viewfinders for steady shots without glare or drained batteries. A lens gathers and focuses light, with different types for purposes like wide angles, telephotos, and macros. An image sensor detects and conveys image information by converting light waves into electronic signals. Common sensor types are CCD, CMOS, and LiveMOS. The aperture is the opening at the rear of the lens that controls how much light reaches the image sensor.
Learn about the advances in LASIK technology that have make LASIK a reality for patients who were at one time not candidates for the procedure. Covered within this presentation are the topics of: Having a LASIK Consultation, Personalized Wavefront Technology, Femtosecond Lasers, Excimer Lasers, and many other advances in LASIK.

This document discusses frame and lens selection based on occupation and age. Key factors in frame selection include comfort, appearance, safety, and suitability for the person's occupation and lifestyle. Different occupations require consideration of visual needs, hazards, and working conditions. Frame material, size, and lens material should be chosen accordingly. For example, plastic frames and polycarbonate lenses are recommended for drivers and industrial or sports workers due to safety concerns. Progressive or multifocal lenses may be suitable for various occupations requiring vision at multiple distances.
Advanced Course In Photography Basic Principles Of PhotographyDaniel Wachtel
This document provides an overview of an advanced photography course, including definitions of key photography principles and terms. It discusses the basic principles of both film and digital photography. It also summarizes the key components and functions of cameras, such as lenses, shutters, and apertures, and how they affect the tonal quality of photographs. The document categorizes different types of cameras based on film size and focusing systems.
This document discusses contact lenses, including their history, advantages over eyeglasses, ideal properties, and materials. Contact lenses are small medical devices that are placed directly on the cornea to correct refractive errors. Some key advantages over eyeglasses are a wider field of view, avoidance of prismatic effects and reflections, and better cosmetic appearance. The ideal contact lens material would provide sufficient oxygen to the cornea, be optically transparent, dimensionally stable, and biocompatible while requiring minimal care. Modern materials include plastics that are easy to manufacture and polish.
This document discusses guidelines for standardized intraoral photography in orthodontic practice:
- Intraoral photographs should be taken at the beginning and end of orthodontic treatment to completely document patient records. They are useful for presentation and documentation.
- Photographs taken during treatment allow orthodontists to double-check for errors in band placement or archwire construction.
- Standardized techniques are needed to make intraoral photography as quick and simple as standardized x-ray procedures. Guidelines for camera choice, lighting, and patient positioning are provided to achieve standardized, diagnostic-quality photographs.
LASIK is a surgical procedure that uses an excimer laser to permanently correct refractive errors like myopia, astigmatism, and hyperopia. The laser reshapes the cornea to improve vision without glasses or contacts. Counselors play an important role in educating patients about LASIK by explaining the benefits and risks, managing expectations, and identifying suitable candidates. Extensive testing and evaluations are done before LASIK to ensure patient safety. The procedure itself is usually quick and painless, and postoperative care involves avoiding dust/dirt and limiting activities for a few weeks to allow healing. Follow-up visits one month and one year later help ensure good outcomes.
Wavefront guided laser surgery - Zyoptic HD ® 2017Bijan Farpour
This document discusses wavefront-guided LASIK surgery. It begins by explaining how the eye works and the different types of refractive errors. It then describes LASIK surgery and how wavefront technology is used to create a detailed map of the eye's optics to customize corneal reshaping. The benefits of wavefront-guided LASIK are reducing quality of vision complaints. Risks include over or undercorrection and potential side effects like glare or dry eyes. Candidates are evaluated on a case-by-case basis regarding their suitability for the procedure.
1) There are a variety of low vision devices that provide magnification to help those with low vision see better for both near and distant tasks. These include spectacle-mounted reading lenses, hand magnifiers, stand magnifiers, and electronic devices like closed-circuit televisions.
2) Low vision devices work by using relative distance magnification, relative size magnification, or angular magnification to enlarge images on the retina. The amount of magnification provided depends on factors like the lens power and working distance.
3) Telescopes are used for distance vision and provide angular magnification to enlarge distant objects. Types include hand-held, bioptic, and telemicroscope models. Proper fitting is important to maximize remaining vision.

Everything a General Practitioner needs to know about Laser Vision Correctionpresmedaustralia
This document summarizes an ophthalmic education event on refractive surgery. It defines refractive surgery as procedures that alter how the eye focuses light to improve vision and reduce dependence on glasses or contacts. The most common refractive surgeries are LASIK, PRK, and lens-based procedures like cataract surgery. LASIK involves creating a corneal flap with a laser and then sculpting the exposed corneal tissue with an excimer laser to correct vision. Risks include over/undercorrection, dry eyes, halos, and infections. The document reviews the LASIK procedure step-by-step and presents clinical cases and the provider's 2013 results, which showed over 96% of LASIK patients achieving good unaided distance vision.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

1. For Photographers, LASIK Can Be
a Real Eye-Opener
Presented by
The American Refractive Surgery Council
with
Dr. Eric Donnenfeld
2. The Hassle of Glasses & Contacts
• By eliminating the hassle
of glasses or contacts,
LASIK makes it easier and
more comfortable to
handle cameras
– Especially the small digital
cameras that are
increasingly popular among
professionals as well as
enthusiastic amateurs
3. Removing Barriers to Great Photos
• Photography is all about eyesight – and it’s also about
removing obstacles between the photographer and what
he sees
• LASIK can be a boon to photographers because it removes
barriers and makes the act of taking pictures much easier
• Many photographers need vision correction, and for
decades, many have relied on eyeglasses or contacts
– But contact lens wearers can be hampered by dust, sand, water or
other harsh environmental conditions that photographers often
encounter
– Glare can be a problem for contact lens wearers as well
4. Viewfinder Issues
• Eyeglasses need to be managed, and can prevent a photographer
from seeing the full image in the viewfinder
• Only the most expensive professional cameras offer full “eye relief”
– the ability to see the full viewfinder image while the eye is a few
inches away from the viewfinder, as would be the case for a
photographer wearing eyeglasses
– Some cameras also offer viewfinders with adjustable diopters that
photographers can set to match their vision correction.
• But less expensive cameras – including compact and Micro Four-
Thirds models increasingly favored by professionals as well as
amateurs – often have small viewfinders that offer little eye relief
– Many of these cameras offer electronic displays that can be hard to read
in bright light – a disadvantage for contact lens wearers and a challenge
for everyone who needs vision correction
5. Simplifying Photography Equipment
• Finally, there’s the simple fact that
photographers need to manage lots
of equipment – cameras, lenses,
batteries – and removing eyeglasses
or contact lens apparatus from the
mix can make their lives in the field
much easier
6. LASIK & Photography
• Dr. Donnenfeld advises that LASIK is surgery, and needs to be taken
seriously:
– Not every person is a good candidate, and there can be risks and side effects
– Choosing a good surgeon – an experienced one who is not necessarily the least
expensive – is important
– Resources available on the Internet, including the American Refractive Surgery Council’s
website, can help photographers explore LASIK and learn what questions to ask when
they consult with a surgeon
• Photographers who turn out to be good candidates for LASIK and who
undergo the procedure will need to go through an adjustment period
– In particular, night vision may be affected until the eye fully heals
– But once healing is complete, the improvement in vision and the added convenience can
make photography a much more pleasurable experience
