Comprehensive eye examination vs. Standard eye examination vs. Prescri

Are the words on your computer starting to blur by mid-afternoon? Maybe even MRT signs have started looking fuzzier than before?

It may be time for an eye check-up. However, not all eye checks cover the same tests or assess the same aspects of your vision and eye health.

The simple rule is that the right eye examination option is based on what you need:

• A basic prescription check generally provides a quick estimate of your lens power

• A standard eye examination assesses your vision and refines your spectacle prescription, conducted by qualified opticians or optometrists at W Optics to help you find suitable lenses for your visual needs and lifestyle.

• A comprehensive eye examination goes further by including additional eye health screening, depending on the selected package, conducted by OOB-registered optometrists at designated W Optics Myopia Centres.

At W Optics, we offer standard and comprehensive eye examinations to suit different needs. Understanding what each involves can help you choose the appropriate service.

1. Prescription Checks: A Quick Check of Your Existing Prescription

A prescription check is a basic assessment that may involve measuring your approximate refractive error using an autorefractor or checking the prescription of your existing spectacles. 

It provides a preliminary indication of your refractive error but does not replace a full eye examination to assess your vision and determine an appropriate spectacle prescription.

What does a prescription check involve?

• Objective refraction (autorefraction)
  An autorefractor uses automated measurements to estimate how light focuses through your eyes and identify possible refractive errors.
• Eye chart test
  Reading letters or symbols on an eye chart helps assess visual acuity at a particular distance (Unassisted or assisted with existing spectacle)
• Checking of existing spectacle prescriptions
  An optical instrument called a lensmeter can measure the prescription of your current glasses.

A basic check may take around five to ten minutes, depending on the provider and exact tests performed. 

A prescription check may be useful when you need a quick indication of your existing spectacle power. However, it is not a substitute for a full eye examination. If you need a more precise prescription or are experiencing blurred vision, a full eye examination may be more appropriate.

At W Optics, a standard eye examination is the minimum examination provided when customers purchase new prescription spectacles, helping ensure their prescription is assessed and refined rather than relying solely on an automated reading.

2. Standard Eye Examination: For Everyday Vision and Spectacle Needs

A standard eye examination at W Optics assesses your vision and helps determine the spectacle prescription needed for clear, comfortable sight. It includes both objective and subjective refraction, alongside an assessment of your visual function and lifestyle needs.

This service is available at all W Optics stores and provides an accessible option for adults and children aged five and above who need a new spectacle prescription or a routine review of their vision.

What does a standard eye examination include?

• Case history and lifestyle assessment
  An eyecare professional discusses your visual symptoms, daily activities and lifestyle, including your screen use and reading habits. This information helps guide the examination and subsequent recommendations.
  

• Objective refraction (autorefraction)
  An autorefractor estimates your refractive error, providing an initial measurement of your spectacle power.
  

• Subjective refraction
  The optician or optometrist refines the prescription by comparing different lens powers and asking which options provide clearer vision. This helps determine the appropriate correction for your needs.
  

• Vision function tests
  These tests assess aspects of how your eyes focus and work together. Depending on the findings, they may help identify visual issues that contribute to discomfort or difficulties with near tasks.
  

• Prescription assessment and vision management
  Based on the examination findings and your visual needs, you’ll be recommended suitable spectacle lenses, such as single-vision or progressive lenses.
  
  Additional tests may be recommended by the attending optometrist when necessary.

Pricing and duration:

At W Optics, a standard eye examination costs S$15 and is suitable for individuals aged five and above. It typically takes around 20–30 minutes, depending on your needs and the assessment required.

The service is available at all W Optics stores islandwide.

Who should get a standard eye examination?

A standard eye examination may be suitable for:

• Individuals experiencing blurred or fluctuating vision

• Students and office workers who spend long hours on digital screens

• First-time spectacle wearers

• Existing spectacle users who need their prescriptions reviewed

• Children and adults who want to monitor their vision through a routine eye examination every 12 months

Regular examinations can help identify changes in vision and determine whether an updated spectacle prescription is needed. If you experience persistent symptoms or have concerns about your eye health, the attending optometrist or optician may recommend further assessment.

3. Comprehensive Eye Examination: A Broader Assessment of Vision and Eye Health

A comprehensive eye examination assesses vision alongside selected aspects of eye health. In addition to determining your spectacle prescription, it includes tests to screen for potential eye conditions, with the specific assessments depending on the selected package and clinical needs.

Some eye conditions, including glaucoma and certain retinal disorders, may develop without noticeable symptoms in their early stages. Appropriate eye health screening can help identify signs that warrant further assessment, although no single examination can detect or rule out every eye condition.

At W Optics, comprehensive eye examinations are available exclusively at designated Myopia Centres and are conducted by OOB-registered optometrists.

What does a comprehensive eye examination include?

The tests offered depend on your age, selected package and individual needs.

• Visual acuity and refraction
  These tests assess how clearly you see and help determine your refractive prescription for conditions such as myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism.
  

• Binocular vision and eye coordination
  These assessments examine how your eyes work together, including aspects of eye alignment and focusing. The specific tests performed depend on the package and clinical requirements.
  

• Glaucoma screening (tonometry)
  Tonometry measures intraocular pressure, which is one factor considered when assessing glaucoma risk. Eye pressure alone cannot confirm or rule out glaucoma, and further examination may be required.
  

• Cataract assessment (slit-lamp biomicroscopy)
  Slit-lamp biomicroscopy allows the practitioner to examine structures at the front of the eye, including the natural lens, for signs of clouding associated with cataracts.
  

• Retinal screening (fundus photography)
  Fundus photography captures images of the back of the eye, including the retina and optic nerve. It can help identify signs of retinal conditions such as diabetic retinopathy and age-related macular degeneration (AMD).
  

• Corneal assessment
  Specialised assessments, such as corneal topography, map the shape and curvature of the cornea. This can help identify irregularities associated with conditions such as keratoconus when clinically indicated.
  

• Ocular surface and tear film assessment
  Tests such as tear break-up time (TBUT) and slit-lamp examination may be used to assess the tear film and ocular surface in people with symptoms suggestive of dry eye or other surface conditions.
  

• Myopia control assessment (for children and teens)
  For younger patients, assessments may include axial length measurement, binocular vision tests and evaluation of myopia progression. These findings can help an optometrist determine whether myopia management options, such as specialised spectacle lenses, contact lenses, Ortho-K or low-dose atropine, may be appropriate.

• Additional specialised tests (OCT and visual field tests)
  Depending on the findings of the initial examination, an optometrist may recommend further investigations such as optical coherence tomography (OCT) or visual field testing.
  
  These specialised tests provide additional information about retinal structures and peripheral vision respectively. They are not included in W Optics’ eye examination packages and are available at an additional cost when recommended.

Who should consider a comprehensive eye examination?

A comprehensive eye examination may be worth considering for:

• Routine comprehensive eye examinations every 12 months for adults and every 6 months for children.
• Adults aged 40 and above, as the risk of certain age-related eye conditions increases with age
• Individuals with a family history of eye disease, including glaucoma or retinal conditions
• People with health conditions such as diabetes or hypertension that may affect eye health
• Children whose myopia is progressing and who may benefit from closer monitoring
• Anyone whose symptoms, history or risk factors indicate that a broader assessment of eye health may be appropriate

Our team at W Optics can advise on the appropriate examination and follow-up frequency based on your age, medical history, symptoms and examination findings.
