Dry eye can have more than one cause
Symptoms may relate to reduced tear production, faster tear evaporation, eyelid or oil-gland problems, environment, screen habits, contact-lens wear, medicines or general health. Assessment helps identify which factors are most relevant.
What the assessment may cover
The optometrist reviews symptoms, timing, screen and workplace exposure, medicines, general health, contact-lens wear, eyelids, tear film, eye surface and prescription. Further testing or referral depends on the findings.
Treatment is matched to the cause
Advice may include environmental and screen changes, blinking and break routines, eyelid care, lubricants or other management pathways. Product choice and frequency should be based on symptoms, examination findings and professional advice.
When not to wait
Pain, marked redness, light sensitivity, injury, sudden vision change, flashes, a curtain-like shadow or a red painful eye in a contact-lens wearer needs prompt or urgent assessment rather than routine self-treatment.
Preparing for an appointment
Bring current eye drops, glasses, contact lenses and solutions, plus a list of medicines and when symptoms are worst. Avoid concealing symptoms with a new product immediately before the examination unless it is needed for comfort or safety.
