Eye blog: plain-English guides to eye health

Each eye speciality at ReNew Vision has its own set of guides, written to answer the questions patients and families commonly ask: what a condition is, which tests are needed, what a treatment involves and when to see an eye doctor. Every speciality page lists its own guides, and new guides appear there as they are written.

How are the guides written?

• In plain English, with the local words people use, such as motibindu for cataract and chashma for spectacles.
• Honest about what is done here. If a treatment is not done at ReNew Vision, the guide says so and explains the referral.
• Careful with medicines. The guides do not name medicines or doses. Eye drops and tablets should only be used as your eye doctor advises.
• No prices and no promises. Costs depend on your eyes and the treatment chosen, and they are explained at the consultation.

Cataract

The cataract section covers the early signs of cataract, the types of cataract surgery, choosing a lens, the lens-power test, what to expect on the day of surgery and care after surgery. Every cataract guide is listed on the cataract surgery page.

Spectacles and the Vision Correction Centre

The vision correction section covers spectacle lenses and frames, reading glasses after 40, progressive and bifocal lenses, children's spectacles, contact lenses, sunglasses and the care of spectacles in Goa's humid weather. See the spectacles and Vision Correction Centre page.

Eye check-ups

The check-up section covers how often to have your eyes checked, what happens during an eye check-up, eye fitness certificates and colour vision tests. See the eye check-up page.

Eye emergencies

The emergency section gives first aid for eye injuries, chemical splashes, something stuck in the eye and sudden loss of vision, listed on the 24-hour emergency eye care page.

• Firecracker eye injury: what to do first, and when to come in (for Narkasur and Diwali)

Other specialities

Guides on red eye and eye flu, dry eye and screen strain, LASIK suitability, diabetic eye disease and the retina, glaucoma, children's eyes and squint, watering eyes, styes and chalazia, and optic nerve problems sit under their own speciality pages. All the specialities are listed on the eye specialities page.

Seasonal eye care in Goa

Some eye problems follow Goa's calendar. Eye flu (conjunctivitis) spreads in the monsoon. Spectacles and contact lenses need extra care in humid weather. Narkasur and Diwali bring firecracker injuries. Strong sun and sea glare make sunglasses with UV protection worth wearing for much of the year.

When is a guide not enough?

A guide cannot examine your eyes. If you have symptoms, book a complete eye check-up during OPD hours (Monday to Saturday, 4 pm to 7 pm). For an eye injury, a chemical in the eye or sudden loss of vision, do not read on: call 072489 88039 and come in. Emergency eye care is available 24 hours, every day.

Questions patients ask

Can the eye blog replace a visit to the eye doctor?

No. The guides are general information to help you understand eye problems and prepare your questions. Only an eye examination can show what is happening in your eyes, and your eye doctor advises you after examining them.

Who are the eye blog guides for?

Patients and families in Vasco, Mormugao, the rest of Goa and nearby areas such as Karwar, Belagavi and Sindhudurg, and anyone in India looking for clear, careful eye health information.

Can I ask a question about my own eyes?

Call or WhatsApp ReNew Vision Eye Hospital on 072489 88039 to book a check-up. Questions about your own eyes can only be answered properly by the eye doctor, after an examination.

What should I do if my eye problem is urgent?

Do not wait to read more. For an eye injury, a chemical in the eye or sudden loss of vision, call 072489 88039 and come in. Emergency eye care is available 24 hours, every day.
